INSPECTION PROCEDURE

HINT:
- As it difficult to reproduce the sensor malfunction, even though diagnosis shows no malfunction, replace the sensor just in case.
- Start the inspection from step 1 in case of using the LEXUS hand-held tester and start from step 5 in case of not using the LEXUS hand-held tester.
