Main Line Between Data Link Connector and ABS Actuator and Electric Unit
(Control Unit)
NKS0054M
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 M15
–Harness connector E108
OK or NG
OK >> GO TO 2.
NG >> Repair the terminal and connector.
2. CHECK HARNESS CONTINUITY (OPEN CIRCUIT)
1. Disconnect the harness connectors M15 and E108.
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 M15.
3. CHECK HARNESS CONTINUITY (OPEN CIRCUIT)
1. Disconnect the connector of ABS actuator and electric unit (control unit).
2. Check the continuity between the harness connector and the ABS actuator and electric unit (control unit)
harness 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 data link connector and the ABS
actuator and electric unit (control unit).
NG >> Replace the main line between the harness connector E108 and the ABS actuator and electric
unit (control unit).

Data Link Connector Branch Line CircuitNKS0054S
INSPECTION PROCEDURE
1. CHECK CONNECTOR
1. Turn the ignition switch OFF.
2. Disconnect the battery cable from the negative terminal.
3. Check the terminals and connectors of the data link connector for damage, bend and loose connection
(connector side and harness side).
OK or NG
OK >> GO TO 2.
NG >> Repair the terminal and connector.
2. CHECK HARNESS FOR OPEN CIRCUIT
Check the resistance between the data link connector terminals.
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 data link connector branch line circuit.
NG >> Repair the data link connector branch line.
Unified Meter and A/C Amp. Branch Line CircuitNKS0054T
INSPECTION PROCEDURE
1. CHECK CONNECTOR
1. Turn the ignition switch OFF.
2. Disconnect the battery cable from the negative terminal.
3. Check the terminals and connectors of the unified meter and A/C amp. for damage, bend and loose con-
nection (unit side and connector side).
OK or NG
