Check Power Supply And Ground Circuit

WARNING: This page is about a different car, the 2003 Nissan Murano. However, it is still accessible from the selected car via links, so may be relevant.

CHECK FUSE

Check for blown fuses.

FUSES CHART

Unit	Power source	Fuse No.
BCM	Battery	F
	Ignition switch ON or START position	1
	Ignition switch ACC or ON position	6
IPDM E/R	Battery	75
		83
		84
		85
		86

Refer to "WIRING DIAGRAM - AUTO/L - ".

OK or NG

OK : GO TO 2.
NG : If fuse is blown, be sure to eliminate cause of malfunction before installing new fuse. Refer to POWER DISTRIBUTION .

CHECK POWER SUPPLY CIRCUIT

Disconnect BCM connector.
Check voltage between BCM connector and ground.

OK or NG

OK : GO TO 3.
NG : Check harness for open or short between BCM and fuse.

CHECK GROUND CIRCUIT

Check continuity between BCM and ground.

Terminals			Continuity
(+)		(-)
Connector	Terminal (Wire color)	(-)
E118	8 (B)	Ground	Yes

OK or NG

OK : INSPECTION END
NG : Check harness ground circuit.
