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. 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, the vehicle is considered not ready for I/M testing.

If the Service engine soon

indicator is on or the bulb does not

work, the vehicle may need to be serviced. Refer to the On board

diagnostics (OBD-II) description in this chapter.

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 is designed to check the emission control system

during normal driving. A complete check may take several days. If the

vehicle is not ready for I/M testing, the following driving cycle consisting

of mixed city and highway driving may be performed:

15 minutes of steady driving on an expressway/highway 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, the above driving cycle will

have to be repeated.

POWER STEERING FLUID

Check the power steering fluid. Refer to scheduled maintenance

information for the service interval schedules.
