Nissan Murano: Dtc/circuit Diagnosis / Abs Branch Line Circuit
Diagnosis Procedure
CHECK CONNECTOR
-
Turn the ignition switch OFF.
-
Disconnect the battery cable from the negative terminal.
-
Check the terminals and connectors of the ABS actuator and electric unit (control unit) for damage, bend and loose connection (unit side and connector side).
Is the inspection result normal?
YES>>
GO TO 2.
NO>>
Repair the terminal and connector.
CHECK HARNESS FOR OPEN CIRCUIT
-
Disconnect the connector of ABS actuator and electric unit (control unit).
-
Check the resistance between the ABS actuator and electric unit (control unit) harness connector terminals.
