Main Line Between VDC/TCS/ABS Control Unit and Data Link ConnectorNKS0054K
INSPECTION PROCEDURE
1. CHECK HARNESS CONTINUITY (OPEN CIRCUIT)
1. Turn the ignition switch OFF.
2. Disconnect the battery cable from the negative terminal.
3. Disconnect the following harness connectors.
–ECM harness connector
–Harness connectors B101 and M73
4. Check the continuity between the Harness connector M73 and the data link connector.
OK or NG
OK >>
Present error: Check the following items again.
–Decision of CAN system type.
–Not received CONSULT-III data [SELF-DIAG RESULTS, CAN DIAG SUPPORT MNTR (“ECU
list” included)].
–Procedure for detecting root cause.

Past error: Error was detected in the main line between the VDC/TCS/ABS control unit and the
data link connector.
NG >> Repair the main line between the harness connector M73 and the data link connector.
