You can correct these temporary

malfunctions by filling the fuel tank with

good quality fuel, properly closing the fuel

fill inlet or letting the electrical system dry

out. After three driving cycles without these

or any other temporary malfunctions

present, the service engine soon indicator

should stay off the next time you start the

engine. A driving cycle consists of a cold

engine startup followed by mixed

city/highway driving. No additional vehicle

service is required.

If the service engine soon indicator remains

on, have your vehicle serviced at the first

available opportunity. Although some

malfunctions detected by the OBD-II may

not have symptoms that are apparent,

continued driving with the service engine

soon indicator on can result in increased

emissions, lower fuel economy, reduced

engine and transmission smoothness, and

lead to more costly repairs.

Readiness for

Inspection/Maintenance (I/M)

Testing

Some state/provincial and local

governments may have

Inspection/Maintenance (I/M) programs

to inspect the emission control equipment

on your vehicle. Failure to pass this

inspection could prevent you from getting

a vehicle registration.

If the service engine soon

indicator is on or the bulb does

not work, you may need to have

the vehicle serviced. See On-Board

Diagnostics (OBD-II).

Your vehicle may not pass the I/M test if

the service engine soon indicator is on or

not working properly (bulb is burned out),

or if the OBD-II system has determined

that some of the emission control systems

have not been properly checked. In this

case, your vehicle is not ready for I/M

testing.

If the vehicle’s engine or transmission has

just been serviced, or the battery has

recently run down or been replaced, the

OBD-II system may indicate that the

vehicle is not ready for I/M testing. To

determine if the vehicle is ready for I/M

testing, turn the ignition key to the on

position for 15 seconds without cranking

the engine. If the service engine soon

indicator blinks eight times, it means that

the vehicle is not ready for I/M testing; if

the service engine soon indicator stays on

solid, it means that the vehicle is ready for

I/M testing.

The OBD-II system monitors the emission

control system during normal driving. A

complete check may take several days. If

the vehicle is not ready for I/M testing, you

may need to perform the following driving

cycle consisting of mixed city and highway

driving:

Drive on an expressway or highway for a

steady 15 minutes, followed by 20 minutes

of stop-and-go driving with at least four

30-second idle periods.

Allow the vehicle to sit for at least eight

hours without starting the engine. Then,

start the engine and complete the above

driving cycle. The engine must warm up to

its normal operating temperature. Once

started, do not turn off the engine until the

above driving cycle is complete. If the

vehicle is still not ready for I/M testing, you

will have to repeat the above driving cycle.
