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
