How to Prepare Your Vehicle for
Inspection/Maintenance (I/M) Testing
In some localities it may become a legal
requirement to pass an Inspection/Maintenance
(I/M) test of the On-Board Diagnostic (OBD) II
system. 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 testing condition. To
prepare for I/M testing, the law specifies that
additional mixed city and highway driving is
required to complete the check of the OBD II
system.
The driving modes required to reach the ready
condition consist of a minimum of 30 minutes of
city and highway driving as described below:
❑ At least twenty minutes driving in stop and go,
city type traffic with at least four idle periods.
❑ At least ten minutes of driving on an
expressway or highway.
Before completing the above driving modes, the
engine must be warmed up and at operating
temperature. Once started, the vehicle must not be
turned off during these driving modes.
Lights and Bulb Replacement
It is a good idea to check the operation of the
following lights frequently:
❑ headlamps
❑ high-mount brakelamp
❑ tail lamps
❑ brakelamps
❑ hazard flasher
❑ turn signals
❑ license plate lamps
