Main Line Between Data Link Connector and TCMUKS005WI
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 M69
–Harness connector E7
OK or NG
OK >> GO TO 2.
NG >> Repair the terminal and connector.
2. CHECK HARNESS CONTINUITY (OPEN CIRCUIT)
1. Disconnect the harness connectors M69 and E7.
2. Check the continuity between the data link connector and the harness connector.
OK or NG
OK >> GO TO 3.
NG >> Repair the main line between the data link connector and the harness connector M69.
3. CHECK HARNESS CONTINUITY (OPEN CIRCUIT)
1. Disconnect the connector of TCM.
2. Check the continuity between the harness connector and the TCM harness 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 data link connector and the TCM.
NG >> Repair the main line between the harness connector E7 and the TCM.
