Readiness for inspection/maintenance (I/M) testing
In some localities, it may be a legal requirement to pass an I/M test of
the on-board diagnostic (OBD-II) system. If your “Check Engine/Service
Engine Soon” light is on, refer to the description in the Warning Lights
and Chimes section of the Instrumentation chapter. Your vehicle may
not pass the I/M test with the “Check Engine/Service Engine Soon” light
on.
If the vehicle’s powertrain system or its battery has just been serviced,
the OBD-II system is reset to a “not ready for I/M test” condition. To
ready the OBD-II system for I/M testing, a minimum of 30 minutes of city
and highway driving is necessary as described below:
• First, at least 10 minutes of driving on an expressway or highway.
• Next, at least 20 minutes driving in stop-and-go, city-type traffic with
at least four 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.
