Emissions Inspection And Maintenance (I/M) Programs - Toyota 2002 Corolla Owner's Manual

'02 Corolla U (L/O 0105)
Emissions Inspection and
Maintenance (I/M) programs
Some states have vehicle emission in-
spection programs which include OBD
(On–Board Diagnostics) checks.
The OBD system monitors the operation
of the emission control system. When the
OBD system determines that a problem
exists somewhere in the emission control
system, the malfunction indicator lamp
comes on. In this case, your vehicle may
not pass the I/M test and need to be
repaired. Contact your Toyota dealer to
service the vehicle.
Even if the malfunction indicator lamp
does not come on, your vehicle may not
pass the I/M test as readiness codes
have not been set in the OBD system.
Readiness codes are automatically set
during ordinary driving. However, when the
battery is disconnected or run down, the
codes are erased. Also, depending on
your driving habits, the codes may not be
completely set.
We recommend you to contact your
Toyota dealer to check the OBD system
before taking the vehicle for testing.
