Circuit/System Verification

  1. Ignition ON.
  2. Verify the scan tool Steering Column Direction Switch parameter changes between Inactive, Forward, Rearward, Up, and Down when exercising the S71 Steering Column Tilt and Telescope Switch.
    • If the parameter does not change 

      Refer to Circuit/System Testing - Switch Malfunction.

    • Go to next step: If the parameter changes 
    3. NOTE:

    Operate the steering column switch in each direction for more than 1 s.

    NOTE:

    When performing the following tests, make sure that the steering column is not already in the position the test is attempting to produce.

  3. Verify the steering column directional motors listed below operate while operating the S71 Steering Column Tilt and Telescope Switch in all directions.
    • M65 Steering Column Telescope Motor
    • M68 Steering Column Tilt Motor
    • If the M65 Steering Column Telescope Motor moves for only.5 s FORWARD or REARWARD 
    1. Wait 5 s.
    2. Operate the S71 Steering Column Tilt and Telescope Switch FORWARD and REARWARD.
      • If the M65 Steering Column Telescope Motor moves for only.5 s FORWARD or REARWARD, replace the M65 Steering Column Telescope Motor
    • If the M65 Steering Column Telescope Motor does not operate FORWARD and REARWARD 

      Refer to Circuit/System Testing - Telescope Motor Malfunction

    • If the M68 Steering Column Tilt Motor moves for only.5 s UP and DOWN 
    1. Wait 5 s.
    2. Operate the S71 Steering Column Tilt and Telescope Switch UP and DOWN.
      • If the M68 Steering Column Tilt Motor moves for only.5 s UP or DOWN, replace the M68 Steering Column Tilt Motor.
    • If the M68 Steering Column Tilt Motor does not operate UP and DOWN 

      Refer to Circuit/System Testing - Tilt Motor Malfunction

    • If both the M65 Steering Column Telescope Motor and the M68 Steering Column Tilt Motor do not operate in any direction 

      Refer to Circuit/System Testing - Steering Column Tilt and Telescope Motor Control Circuit Test.

    • Go to next step: If both the M65 Steering Column Telescope Motor and the M68 Steering Column Tilt Motor operate 
  4. All OK.
