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 city and highway driving is necessary 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:
248
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
