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 diagnostics system. If your “Check Engine/Service Engine

Soon” light is on, refer to the description in the Warning lights and

chimes section of the Instrument cluster 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 on-board diagnostics system is reset to a “not ready for I/M test”

condition. To ready the on-board diagnostics 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.
