WARNING: This page is about a different car, the 2004 Infiniti M45. However, it is still accessible from the selected car via links, so may be relevant.

CHECK FUNCTION
With CONSULT-II

With "TILT SEN" on the DATA MONITOR, operate the tilt switch to check that the voltage changes.

OK or NG
1. OK: System is OK.
2. NG: GO TO 2.
CHECK TILT STEERING MECHANISM
Check the operation malfunction caused by steering wheel tilt mechanism deformation or parts are loose.

OK or NG
1. OK: GO TO 3.
2. NG: Repair the malfunctioning parts.
CHECK HARNESS
1. Disconnect BCM connector and tilt sensor connector.
2. Check continuity harness between BCM connector M4 terminals 46 (LG/R), 53 (L/B), 54 (R) and tilt sensor connector M57 terminals 1 (R), 2 (LG/R), 3 (L/B).
  46 (LG/R) - 2 (LG/R): Continuity should exist.
  
  53 (L/B) - 3 (L/B): Continuity should exist.
  
  54 (R) - 1 (R): Continuity should exist.
3. BCM connector M4 terminals 46 (LG/R), 53 (L/B), 54 (R) and body ground.
  46 (LG/R) - Ground: Continuity should not exist.
  
  53 (L/B) - Ground: Continuity should not exist.
  
  54 (R) - Ground: Continuity should not exist.
