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.
