2003 Honda Accord Coupe Owners Manual

To check if they are set, turn the ignition ON (II), but do not start the engine. The Malfunction Indicator Lamp will come on for 20 seconds. If it then goes off, the readiness codes are set. If it blinks 5 times, the readiness codes are not set.

Malfunction Indicator Lamp

Readiness Codes Your car has certain ‘‘readiness codes’’ that are part of the on-board diagnostics for the emissions systems. In some states, part of the emissions testing is to make sure these codes are set. If they are not set, the test cannot be completed.

If your car’s battery has been disconnected or gone dead, these codes are erased. It takes several days of driving under various conditions to set the codes again.

BRAKE SYSTEM INDICATOR

＊

U.S. indicator shown ＊

The Brake System Indicator normally comes on when you turn the ignition switch ON (II). It is a reminder to check the parking brake. It comes on and stays lit if you do not fully release the parking brake.

If it comes on at any other time, it indicates a problem with the car’s brake system. In most cases, the problem is a low fluid level in the brake fluid reservoir. Press lightly on the brake pedal to see if it feels normal. If it does, check the brake fluid level the next time you stop at a service station (see page ). If the fluid level is low, take the car to your dealer and have the brake system inspected for leaks or worn brake pads.

313

However, if the brake pedal does not feel normal, you should take immediate action. Because of the brake system’s dual-circuit design, a problem in one part of the system will still give you braking at two wheels. You will feel the brake pedal go down much farther before the car begins to slow down, and you will have to press harder on the pedal. The distance needed to stop will be much longer.

Brake System Indicator

Slow down by shifting to a lower gear, and pull to the side of the road when it is safe. Because of the longer distance needed to stop, it is hazardous to drive the car. You should have it towed, and repaired as Emergency soon as possible. (See Towing .) 391

on page

If you must drive the car a short distance in this condition, drive slowly and cautiously.

If the ABS indicator comes on with this indicator, have the car inspected by your Honda dealer immediately.

Closing the Moonroof

OnEXandEX-V6models If the electric motor will not close the moonroof, do the following:

1.

2.

Check the fuse for the moonroof motor (see page ). If the fuse is blown, replace it with one of the same or lower rating.

390

Try closing the moonroof. If the new fuse blows immediately or the moonroof motor still does not operate, you can close the moonroof manually.

3.

Get the moonroof wrench out of the tool kit in the trunk.

Checking and Replacing Fuses If something electrical in your car stops working, the first thing you should check for is a blown fuse. Determine from the chart on pages , or the diagram on the 389
fuse box lid, which fuse or fuses control that component. Check those fuses first, but check all the fuses before deciding that a blown fuse is not the cause. Replace any blown fuses and check the component’s operation.

1.

Turn the ignition switch to LOCK (0). Make sure the headlights and all other accessories are off.

2.

Remove the cover from the fuse box.

If you cannot drive the car without fixing the problem, and you do not have a spare fuse, take a fuse of the same rating or a lower rating from one of the other circuits. Make sure you can do without that circuit temporarily (such as the accessory power socket or radio).

If you replace the blown fuse with a spare fuse that has a lower rating, it might blow out again. This does not indicate anything wrong. Replace the fuse with one of the correct rating as soon as you can.

Replacing a f use with one that has a higher rating greatly increases the chances of damaging the electrical system. If you do not have a replace- ment f use with the proper rating f or the circuit, install one with a lower rating.

6.

If the replacement fuse of the same rating blows in a short time, there is probably a serious electrical problem in your car. Leave the blown fuse in that circuit and have your car checked by a qualified mechanic.

Look for a burned wire inside the fuse. If it is burned, replace it with one of the spare fuses of the same rating or lower.

If your car needs to be towed, call a professional towing service or, if you belong to one, an organization that provides roadside assistance. Never tow your car behind another vehicle with just a rope or chain. It is very dangerous.

There are three popular types of professional towing equipment.

−

The operator Flat-bedEquipment loads your car on the back of a truck. This is the best way to transport your Honda.

−

The tow

Wheel-liftEquipment truck uses two pivoting arms that go under the tires (front or rear) and lift them off the ground. The other two This is tires remain on the ground. an acceptable way to tow your Honda.

−

The tow

Sling-typeEquipment truck uses metal cables with hooks on the ends. These hooks go around parts of the frame or suspension and the cables lift that end of the car off the ground. Your car’s suspension and body can be seriously damaged. This method of towing is unacceptable.

If your Honda cannot be transported by flat-bed, it should be towed by wheel-lift equipment with the front wheels off the ground. If due to damage, your car must be towed with the front wheels on the ground, do the following:

ManualTransmission:

Release the parking brake. Shift the transmission to Neutral.

Emergency Towing

AutomaticTransmission:

Release the parking brake. Start the engine. Shift to D, then to N. Turn off the engine.

Improper towing preparation will damage the transmission. Follow the above procedure exactly. If you cannot shif t the transmission or start the engine (automatic transmission), your car must be transported with the f ront wheels of f the ground.

With the front wheels on the ground, it is best to tow the car no farther than 50 miles (80 km), and keep the speed below 35 mph (55 km/h).

If your car is equipped with a front spoiler, remove it before towing so it is not damaged.

Trying to lif t or tow your car by the bumpers will cause serious damage. The bumpers are not designed to support the car’s weight.

Emergency Towing

If you decide to tow your car with all four wheels on the ground, make sure you use a properly-designed and attached tow bar. Prepare the car for towing as described above, and leave the ignition switch in Accessory (I) so the steering wheel does not lock. Make sure the radio and any items plugged into the accessory power socket are turned off so they do not run down the battery.

The steering system can be damaged if the steering wheel is locked. Leave the ignition switch in Accessory (I), and make sure the steering wheel turns f reely bef ore you begin towing.

Identification Numbers

Your car has several identifying numbers located in various places.

The Vehicle Identification Number (VIN) is the 17-digit number your Honda dealer uses to register your car for warranty purposes. It is also necessary for licensing and insuring your car. The easiest place to find the VIN is on a plate fastened to the top of the dashboard. You can see it by looking through the windshield on the driver’s side. It is also on the Certification label attached to the driver’s doorjamb, and is stamped on the engine compartment bulkhead. The VIN is also provided in bar code on the Certification label.

DOT Tire Quality Grading (U.S. Cars)

Treadwear The treadwear grade is a compara- tive rating based on the wear rate of the tire when tested under controlled conditions on a specified government test course. For example, a tire graded 150 would wear one and one- half (1 1/2) times as well on the government course as a tire graded 100. The relative performance of tires depends upon the actual condi- tions of their use, however, and may depart significantly from the norm due to variations in driving habits, service practices and differences in road characteristics and climate.

The tires on your car meet all U.S. Federal Safety Requirements. All tires are also graded for treadwear, traction, and temperature perform- ance according to Department of Transportation (DOT) standards. The following explains these gradings.

Uniform Tire Quality Grading Quality grades can be found where applicable on the tire sidewall between the tread shoulder and the maximum section width. For example:

Treadwear 200
Traction AA Temperature A

All passenger car tires must conform to Federal Safety Requirements in addition to these grades.

400

Technical Information

−

AA, A, B, C

Traction The traction grades, from highest to lowest, are AA, A, B, and C. Those grades represent the tire’s ability to stop on wet pavement as measured under controlled conditions on specified government test surfaces of asphalt and concrete. A tire marked C may have poor traction performance.

Warning: The traction grade assigned to this tire is based on straight-ahead braking traction tests, and does not include acceleration, cornering, hydroplaning, or peak traction characteristics.

Main MenuTable of Contentsst０２／１１／１８　２３：３０：４８　３１ＳＤＰ６００　０４０４　

−

A, B, C

Temperature The temperature grades are A (the highest), B, and C, representing the tire’s resistance to the generation of heat and its ability to dissipate heat when tested under controlled conditions on a specified indoor laboratory test wheel. Sustained high temperature can cause the material of the tire to degenerate and reduce tire life, and excessive temperature can lead to sudden tire failure. The grade C corresponds to a level of performance which all passenger car tires must meet under the Federal Motor Vehicle Safety Standard No. 109. Grades B and A represent higher levels of performance on the laboratory test wheel than the minimum required by law.

DOT Tire Quality Grading (U.S. Cars)

Warning: The temperature grade for this tire is established for a tire that is properly inflated and not over- loaded. Excessive speed, underinfla- tion, or excessive loading, either separately or in combination, can cause heat buildup and possible tire failure.

Oxygenated Fuels

Some conventional gasolines are being blended with alcohol or an ether compound. These gasolines are collectively referred to as oxygenated fuels. To meet clean air standards, some areas of the United States and Canada use oxygenated fuels to help reduce emissions.

If you use an oxygenated fuel, be sure it is unleaded and meets the minimum octane rating requirement.

Before using an oxygenated fuel, try to confirm the fuel’s contents. Some states/provinces require this information to be posted on the pump.

402

Technical Information

The following are the U.S. EPA and Canadian CGSB approved percentages of oxygenates:

ETHANOL (ethyl or grain alcohol) You may use gasoline containing up to 10 percent ethanol by volume. Gasoline containing ethanol may be marketed under the name ‘‘Gasohol.’’

(Methyl Tertiary Butyl

MTBE Ether) You may use gasoline containing up to 15 percent MTBE by volume.

(methyl or wood

METHANOL alcohol) Your car was not designed to use fuel that contains methanol. Methanol can corrode metal parts in the fuel system, and also damage plastic and rubber components. This damage would not be covered by your warranties.

If you notice any undesirable operating symptoms, try another service station or switch to another brand of gasoline.

Fuel system damage or performance problems resulting from the use of an oxygenated fuel containing more than the percentages of oxygenates given above are not covered under warranty.

Main MenuTable of Contentsst０２／１１／１８　２３：３１：０２　３１ＳＤＰ６００　０４０６　

Driving in Foreign Countries

If you are planning to take your Honda outside the U.S. or Canada, contact the tourist bureaus in the areas you will be traveling in to find out about the availability of unleaded gasoline with the proper octane rating.

If unleaded gasoline is not available, be aware that using leaded gasoline in your Honda will affect perfor- mance and fuel mileage, and damage its emissions controls. It will no longer comply with U.S. and Canadian emissions regulations, and will be illegal to operate in North America. To bring your car back into compliance will require the replace- ment of several components, such as the oxygen sensors and the three way catalytic converter. These re- placements are not covered under warranty.

Technical Information 403

Emissions Controls

The burning of gasoline in your car’s engine produces several byproducts. Some of these are carbon monoxide (CO), oxides of nitrogen (NOx) and hydrocarbons (HC). Gasoline evaporating from the tank also produces hydrocarbons. Controlling the production of NOx, CO, and HC is important to the environment. Under certain conditions of sunlight and climate, NOx and HC react to form photochemical ‘‘smog.’’ Carbon monoxide does not contribute to smog creation, but it is a poisonous gas.

＊

The Clean Air Act The United States Clean Air Act sets standards for automobile emissions. It also requires that automobile manufacturers explain to owners how their emissions controls work and what to do to maintain them. This section summarizes how the emissions controls work. Scheduled maintenance is on page 274

In Canada, Honda vehicles comply

with the Canadian emission requirements, as specified in an agreement with Environment Canada, at the time they are manufactured.

Crankcase Emissions Control System Your car has a Positive Crankcase Ventilation System. This keeps gasses that build up in the engine’s crankcase from going into the atmosphere. The Positive Crankcase

Technical Information

Ventilation valve routes them from the crankcase back to the intake manifold. They are then drawn into the engine and burned.

Evaporative Emissions Control System As gasoline evaporates in the fuel tank, an evaporative emissions control canister filled with charcoal adsorbs the vapor. It is stored in this canister while the engine is off. After the engine is started and warmed up, the vapor is drawn into the engine and burned during driving.

Onboard Refueling Vapor Recovery The Onboard Refueling Vapor Recovery (ORVR) system captures the fuel vapors during refueling. The vapors are adsorbed in a canister filled with activated carbon. While driving, the fuel vapors are drawn into the engine and burned off.

Exhaust Emissions Controls The exhaust emissions controls include four systems: PGM-FI, Ignition Timing Control, Exhaust Gas Recirculation and Three Way Catalytic Converter. These four systems work together to control the engine’s combustion and minimize the amount of HC, CO, and NOx that comes out the tailpipe. The exhaust emissions control systems are separate from the crankcase and evaporative emissions control systems.

PGM-FISystem The PGM-FI System uses sequential multiport fuel injection. It has three subsystems: Air Intake, Engine Control, and Fuel Control. The Engine Control Module (ECM) or the Powertrain Control Module (PCM) uses various sensors to determine how much air is going into the engine. It then controls how much fuel to inject under all operat-

ing conditions.

IgnitionTimingControlSystem This system constantly adjusts the ignition timing, reducing the amount of HC, CO, and NOx produced.

ExhaustGasRecirculation(EGR) System The Exhaust Gas Recirculation (EGR) system takes some of the exhaust gas and routes it back into the intake manifold. Adding exhaust gas to the air/fuel mixture reduces the amount of NOx produced when the fuel is burned.

ThreeWayCatalyticConverter The three way catalytic converter is in the exhaust system. Through chemical reactions, it converts HC, CO, and NOx in the engine’s exhaust to carbon dioxide (CO ), nitrogen (N), and water vapor.

Emissions Controls

Replacement Parts The emissions control systems are designed and certified to work to- gether in reducing emissions to levels that comply with the Clean Air Act. To make sure the emissions remain low, you should use only new genuine Honda replacement parts or their equivalent for repairs. Using lower quality parts may increase the emissions from your car.

The emissions control systems are covered by warranties separate from the rest of your car. Read your warranty manual for more informa- tion.

Three Way Catalytic Converter

The three way catalytic converter contains precious metals that serve as catalysts, promoting chemical reactions to convert the exhaust gasses without affecting the metals. The catalytic converter is referred to as a three-way catalyst, since it acts on HC, CO, and NOx. A replacement unit must be an original Honda part or its equivalent.

The three way catalytic converter must operate at a high temperature for the chemical reactions to take place. It can set on fire any com- bustible materials that come near it. Park your car away from high grass, dry leaves, or other flammables.

Technical Information

THREE WAY CATALYTIC CONVERTERS 6-cylinder models Keep the engine tuned-up.

Have your car diagnosed and repaired if it is misfiring, back- firing, stalling, or otherwise not running properly.

THREE WAY CATALYTIC CONVERTER 4-cylinder models A defective three way catalytic converter contributes to air pollution, and can impair your engine’s per- formance. Follow these guidelines to protect your car’s three way catalytic converter.

Always use unleaded gasoline. Even a small amount of leaded gasoline can contaminate the catalyst metals, making the three way catalytic converter ineffective.

Testing of Readiness Codes If you take your car for a state emissions test shortly after the battery has been disconnected or gone dead, it may not pass the test. This is because of certain ‘‘readiness codes’’ that must be set in the on- board diagnostics for the emissions systems. These codes are erased when the battery is disconnected, and set again only after several days of driving under a variety of conditions.

If the testing facility determines that the readiness codes are not set, you will be requested to return at a later date to complete the test. If you must get the car re-tested within the next two or three days, you can condition the car for re-testing by doing the following.

Make sure the gas tank is nearly, but not completely, full (around 3/4).

Make sure the car has been parked with the engine off for 8
hours or more.

Make sure the ambient temperature is between 20° and 95°F.

State Emissions Testing

Without touching the accelerator pedal, start the engine and let it idle for 20 seconds.

Keep the car in Park (automatic transmission) or Neutral (manual transmission). Increase the engine speed to 2,000 rpm and hold it there until the temperature gauge rises to at least 1/4 of the scale (approximately 3 minutes).

State Emissions Testing

Select a nearby lightly traveled major highway where you can maintain a speed of 50 to 60 mph (80 to 97 km/h) for at least 20
minutes. Drive on the highway in D (A/T) or 5th/6th (M/T). Do not use the cruise control. When traffic allows, drive for 90 seconds without moving the accelerator pedal. (Vehicle speed may vary slightly; this is okay.) If you cannot do this for a continuous 90
seconds because of traffic conditions, drive for at least 30
seconds, then repeat it two more times (for a total of 90 seconds).

Then drive in city/suburban traffic for at least 10 minutes. When traffic conditions allow, let the car coast for several seconds without using the accelerator pedal or the brake pedal.

If the testing facility determines the readiness codes are still not set, see your Honda dealer.
