INSPECTION PROCEDURE
HINT:
According to the DATA LIST displayed by the OBD II scan tool or hand-held tester, you can read the value
of the switch, sensor, actuator and so on without parts removal. Reading the DATA LIST as the first step of
troubleshooting is one method to shorten labor time.
(a) Turn the ignition switch off.
(b) Connect the OBD II scan tool or hand-held tester to the DLC3.
(c) Turn the ignition switch to the ON position.
(d) Push the ºONº button of the OBD II scan tool or the hand-held tester.
