Nissan Murano: Dtc/circuit Diagnosis / Dlc Branch Line Circuit
Diagnosis Procedure
CHECK CONNECTOR
-
Turn the ignition switch OFF.
-
Disconnect the battery cable from the negative terminal.
-
Check the following terminals and connectors for damage, bend and loose connection (unit side and connector side).
-
Data link connector
-
3CH CAN gateway
Is the inspection result normal?
YES>>
GO TO 2.
NO>>
Repair the terminal and connector.
CHECK HARNESS CONTINUITY (OPEN CIRCUIT)
-
Disconnect the connector of 3CH CAN gateway.
-
Check the continuity between the 3CH CAN gateway harness connector terminals.

The autolight system allows the headlights
to turn on and off automatically. The autolight
system can:
Turn on the headlights, front parking,
tail, license plate and instrument panel
lights automatically when it is dark.
Turn off all the lights (except daylight
running lights) when it is light.
Keep all the lights on for a period of time
after you place the ignition switch in the
OFF position and all doors are closed.
