Inspection Procedure
WARNING: This page is about a different car, the 2006 Nissan Xterra. However, it is still accessible from the selected car via links, so may be relevant.
- CHECK SELF-DIAGNOSIS RESULT
Check self-diagnosis results.
SELF-DIAGNOSIS RESULTSelf-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
- Turn ignition switch OFF.
- 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.
- 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
- Turn ignition switch ON.
- Check voltage between steering angle sensor harness connector M47 and body ground.VOLTAGE REFERENCE CHART

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.
STEERING CONDITION DATA MONITOR
| Steering condition | Data monitor |
|---|---|
| Straight-ahead | -3.5 deg to +3.5 deg |
| Turn wheel to the right by 90Ω | Approx. - 90deg |
| Turn wheel to the left by 90Ω | 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 ".
