How to Prepare Your Vehicle for
Inspection/Maintenance (I/M) Testing
*
[MC32400(ALL)05/96]
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.
