[SV51457( ALL)06/95]
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 ªnot ready for I/M testingº condition. To
prepare for I/M testing, the law specifies a
ªneed for additional mixed city and highway
driving to complete the checkº of the OBD II
system. As soon as all of the OBD II system
checks are successfully completed, the OBD II
system is set to the ready condition. The amount
of driving required to reach the ready condition
varies with individual driving patterns. To
complete this requirement in the minimum
amount of time, refer to the OBD II Drive Cycle
defined below. If the vehicle owner cannot or
does not want to do the additional driving
required by law, a service center can perform
this drive cycle as it would any other type of
repair work.
