4266-2. Maintenance
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.
●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.
The error code in the OBD system will not be cleared unless the vehi-
cle is driven 40 or more times.
Contact your Toyota dealer to prepare the vehicle for re-testing.
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
Your vehicle may not pass the I/M test in the following situations:
When the malfunction indicator lamp still remains on after sev-
eral driving trips
If your vehicle does not pass the I/M test

●Make sure that the “READY” indicator is off.
●Keep hands, clothing and tools away from the moving fan and engine
drive belt.
●Be careful not to touch the engine, power control unit, radiator, exhaust

may also be hot.
●Do not leave anything that may burn easily, such as paper and rags, in the
engine compartment.
●Do not smoke, cause sparks or expose an open flame to fuel. Fuel fumes
are flammable.
■When working near the electric cooling fan or radiator grille
Be sure the power switch is off.
With the power switch in ON mode, the electric cooling fan may automati-
cally start to run if the air conditioning is on and/or the coolant temperature
is high. (P. 437)
■Safety glasses
Wear safety glasses to prevent flying or falling material, fluid spray, etc.
from getting in your eyes.
