6-2. Maintenance

The OBD system determines that a 
problem exists somewhere in the emis-
sion 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.



When the battery is disconnected 
or discharged

Readiness codes that are set during ordi-
nary 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.

The error code in the OBD system will 
not be cleared unless the vehicle is 
driven 40 or more times.

Contact your Lexus dealer to prepare 
the vehicle for re-testing.

Emission inspection and 
maintenance (I/M) pro-
grams

Some states have vehicle emission 
inspection programs which include 
OBD (On Board Diagnostics) 
checks. The OBD system monitors 
the operation of the emission con-
trol system.

If the malfunction indicator lamp 
comes on

Your vehicle may not pass the 
I/M test in the following situa-
tions:

When the malfunction indicator 
lamp still remains on after sev-
eral driving trips

If your vehicle does not pass the 
I/M test
