- When the 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 Toyota dealer to prepare the vehicle for re-testing.
