Check Telescopic Motor Circuit

1. CHECK STEERING WHEEL TELESCOPIC MECHANISM 

   Check following.

   • Operation malfunction caused by steering wheel telescopic mechanism deformation or pinched harness or 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 and check again.

2. CHECK FUNCTION 

   With CONSULT-II 

   Check operation with "TELESCO MOTOR" in ACTIVE TEST.

   Test item	Description
   TELESCO MOTOR	The telescopic motor is activated by receiving the drive signal.

   OK or NG 

   OK: Steering telescopic motor circuit is OK.

   NG: GO TO 3.

3. CHECK TELESCOPIC MOTOR HARNESS CONTINUITY 
   1. Turn ignition switch OFF.
   2. Disconnect automatic drive positioner control unit and tilt motor and telescopic motor connector.
   3. Check continuity between automatic drive positioner control unit connector M50 terminals 36, 44 and tilt motor and telescopic motor connector M27 terminals 3, 4.

      36 (L/R) - 3 (L/R) : Continuity should exist. 

      44 (L/W) - 4 (L/W) : Continuity should exist. 

   4. Check continuity between automatic drive positioner control unit connector M50 terminals 36, 44 and ground.

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

      44 (L/W) - Ground :Continuity should not exist.

   OK or NG 

   OK: GO TO 4.

   NG: Repair or replace harness between automatic drive positioner control unit and tilt motor and telescopic motor.

4. CHECK BCM OUTPUT SIGNAL 

1. Connect the automatic drive positioner control unit connector.
2. Telescopic switch operate, check voltage between automatic drive positioner control unit connector and ground.
