Check Tilt Motor Circuit

Check following.

• Operation malfunction caused by steering wheel tilt mechanism deformation or pinched harness and other foreign materials
• Operation malfunction and interference with other parts by poor installation

OK or NG 

OK :

• GO TO 2 (With CONSULT-II).
• GO TO  3 (Without CONSULT-II).

NG : Repair the malfunctioning part.

With CONSULT-II 

Check operation with "TILT MOTOR" in ACTIVE TEST.

OK or NG 

OK : Steering tilt motor circuit is OK.

NG : GO TO 3.

1. Turn ignition switch OFF.
2. Disconnect automatic drive positioner control unit connector and tilt and telescopic motor connector.
3. Check continuity between automatic drive positioner control unit connector M50 terminals 35, 42 and tilt and telescopic motor connector M27 terminals 1, 2.

   35 (R/L) - 1 (R/L) : Continuity should exist. 

   42 (R/B) - 2 (R/B) : Continuity should exist. 

4. Check continuity between automatic drive positioner control unit connector M50 terminals 35, 42 and ground.

   35 (R/L) - Ground : Continuity should not exist. 

   42 (R/B) - Ground : Continuity should not exist.
