Emission inspection and maintenance (I/M)
programs
Some states have vehicle emission inspection programs which
include OBD (On Board Diagnostics) checks. The OBD system
monitors the operation of the emission control system.
If the malfunction indicator lamp comes on
The OBD system determines that a problem exists somewhere in the
emission control system. Your vehicle may not pass the I/M test and
may need to be repaired. Contact your Toyota dealer to service the
vehicle.
Your vehicle may not pass the I/M test in the following situations:
● When the battery is disconnected or discharged
Readiness codes that are set during ordinary driving are erased.
Also, depending on your driving habits, the readiness codes may
not be completely set.
● When the fuel tank cap is loose
The malfunction indicator lamp illuminates, indicating a temporary
malfunction, and your vehicle may not pass the I/M test.
When the malfunction indicator lamp remains on after several
driving trips
An OBD system error code will not be cleared unless the vehicle is
driven 40 or more times.
If your vehicle does not pass the I/M test
Contact your Toyota dealer to prepare the vehicle for re-testing.
