Telescopic Motor Circuit Inspection

  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

    1. OK: GO TO 2.
    2. NG: Repair the malfunctioning part and check again.
  2. CHECK FUNCTION 

    With CONSULT-II 

    Check operation with "TELESCO MOTOR" in ACTIVE TEST.

    Without CONSULT-II 

    GO TO 3.

    OK or NG

    1. OK: Steering telescopic motor circuit is OK.
    2. 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 (L/R), 44 (L/W) and tilt motor and telescopic motor connector M27 terminals 3 (L/R), 4 (L/W).

      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 (L/R), 44 (L/W) and ground.

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

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

    OK or NG

    1. OK: GO TO 4.
    2. 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 and tilt motor and telescopic motor connector.
    2. Check voltage between automatic drive positioner control unit connector and ground.
