Inspection Procedure

WARNING: This page is about a different car, the 2006 Nissan Pathfinder. However, it is still accessible from the selected car via links, so may be relevant.

CHECK SELF-DIAGNOSIS RESULT

Check self-diagnosis results.

STEERING ANGLE SENSOR SYSTEM

Self-diagnosis results
ST ANGLE SEN CIRCUIT
ST ANG SEN COM CIR

Is above displayed in self-diagnosis item?

YES: GO TO 2.

NO: Inspection End.

CHECK CONNECTOR
1. Disconnect steering angle sensor connector M47 and ABS actuator and electric unit (control unit) connector E125 and check terminals for deformation, disconnection, looseness, or damage. Repair or replace as necessary.
2. Reconnect connectors and repeat ABS actuator and electric unit (control unit) self-diagnosis.
Is "ST ANGLE SEN CIRCUIT" or "ST ANG SEN COM CIR" displayed?

YES: GO TO 3.

NO: Inspection End.

CHECKING STEERING ANGLE SENSOR POWER AND GROUND

Check voltage between steering angle sensor harness connector M47 and body ground.

STEERING ANGLE SENSOR POWER AND GROUND

Terminals			Measured value (Approx.)
(+)		(-)
Steering angle sensor connector	Terminal	(-)
M47	1	Ground	12V
M47	3	Ground	12V

OK or NG

OK: GO TO 4.

NG: Repair the circuit.

CHECK STEERING ANGLE SENSOR HARNESS

Check CAN communication system. Refer to "CAN COMMUNICATION ".
Disconnect steering angle sensor connector M47 and ABS actuator and electric unit (control unit) connector E125.
Check continuity between ABS actuator and electric unit (control unit) connector E125 and steering angle sensor connector M47.

STEERING ANGLE SENSOR HARNESS

A		B		Continuity
Connector	Terminal	Connector	Terminal	Continuity
ABS actuator and electric unit (control unit): E125	11	Steering angle sensor: M47	4	Yes
ABS actuator and electric unit (control unit): E125	15	Steering angle sensor: M47	5	Yes

OK or NG

OK: GO TO 5.

NG: Repair or replace harness.

CHECK STEERING WHEEL PLAY
Check steering wheel play. Refer to "CHECKING STEERING WHEEL PLAY ".

OK or NG

OK: GO TO 6.

NG: Adjust steering wheel play.

CHECK DATA MONITOR

Connect steering angle sensor and ABS actuator and electric unit (control unit) connectors.
Use "DATA MONITOR" to check if the status of "STR ANGLE SIG" is normal.

DATA MONITOR

Steering condition	Data monitor
Straight-ahead	-3.5 deg to +3.5 deg
Turn wheel to the right by 90°	Approx. - 90deg
Turn wheel to the left by 90°	Approx. + 90deg

OK or NG

OK: Perform ABS actuator and electric unit (control unit) self-diagnosis again.

NG: Replace spiral cable (steering angle sensor) and adjust neutral position of steering angle sensor.

Refer to "ADJUSTMENT OF STEERING ANGLE SENSOR NEUTRAL POSITION ".
