INSPECTION PROCEDURE
1. CHECK CONNECTOR
1. Turn the ignition switch OFF.
2. Disconnect the battery cable from the negative terminal.
3. Check the following terminals and connectors for damage, bend and loose connection (connector side
and harness side).
–Harness connector M61
–Harness connector M62
OK or NG
OK >> GO TO 2.
NG >> Repair the terminal and connector.
2. CHECK HARNESS CONTINUITY (OPEN CIRCUIT)
1. Disconnect the following harness connectors.
–Harness connectors F102 and M72
–Harness connectors M61 and M62
2. Check the continuity between harness connectors.
OK or NG
OK >> GO TO 3.
NG >> Repair the main line between the harness connector M72 and M61.
3. CHECK HARNESS CONTINUITY (OPEN CIRCUIT)
Check the continuity between the harness connector and the data link connector.
OK or NG
OK >>
Present error: Check the following items again.
–Decision of CAN system type.
–Not received CONSULT-II data (SELECT SYSTEM, SELF-DIAG RESULTS, CAN DIAG SUP-
PORT MNTR).
–Procedure for detecting root cause.

Past error: Error was detected in the main line between the TCM and the data link connector.
NG >> Repair the main line between the harness connector M62 and the data link connector.
