4-2. Maintenance

Maintenance and care
CT200h_U (OM76040U)
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 oper-
ation 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 Lexus dealer to service
the vehicle.
■
Your vehicle may not pass the I/M test in the following situations:
●
When the 12-volt 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 comes on indicating a temporary
malfunction and your vehicle may not pass the I/M test.
■
When the malfunction indicator lamp still remains on after several
driving trips
The error code in the OBD system 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 Lexus dealer to prepare the vehicle for re-testing.
