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 emis-
sion control system.
When 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.
Situations your vehicle may not pass the I/M test
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, depend-
ing 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.
When your vehicle does not pass the I/M test
Contact your Lexus dealer to prepare the vehicle for re-testing.

Do-it-yourself service precautions
If you perform maintenance by yourself, be sure to follow the correct procedure as
given in the section for each part.
WARNING
The engine compartment contains many mechanisms and fluids that may move suddenly,
become hot, or become electrically charged. Observe the following precautions.
■
When working on the engine compartment
●
Keep hands, clothing and tools away from the moving fan and engine drive belt.

Be sure the engine switch is OFF.
With the engine switch in ON, the electric cooling fan may automatically start to run if the
air conditioning is on or the coolant temperature is high.
■
Safety glasses
Wear safety glasses to prevent flying or falling material, fluid spray, etc., from getting in
your eyes.
