Diagnostic Test

  1. 1) DTC IS ACTIVE 

    Ignition on, engine not running.

    With the Scan Tool, select Clear Stored DTCs in the Memory Seat Module.

    Move the Steering Column Telescope Switch to the Forward and Rearward positions several times, holding the switch in position for at least 2 seconds each time.

    With the Scan Tool, select View DTCs in the Memory Seat Module.

    Does the DTC reset and/or remain active? 

    Yes 

    1. Go to  2).

    No 

    1. Go to  6).
  2. 2) CHECK DTC WITH HARNESS DISCONNECTED 

    Turn the ignition off.

    Disconnect the Steering Column Telescope Motor connector.

    Turn the ignition on.

    Move the Steering Column Telescope Switch to the Forward and Rearward positions several times.

    With the Scan Tool, select Clear Stored DTCs in the Memory Seat Module.

    Move the Steering Column Telescope Switch to the Forward and Rearward positions several times, holding the switch in position for at least 2 seconds each time.

    With the Scan Tool, select View DTCs in the Memory Seat Module.

    Does the DTC reset and/or remain active? 

    Yes 

    1. Go to  4).

    No 

    1. Go to  3).
  3. 3) STEERING COLUMN TELESCOPE MOTOR 

    View repair.

    Repair 

    1. Inspect the wiring between the Steering Column Telescope Motor and the harness connector (on the motor side) for a short to ground or to any other circuit. If any problems are found, repair as necessary. If no problems are found, replace the Steering Column Telescope Motor in accordance with the Service Information.

    Turn the ignition off.

    Disconnect the Memory Seat Module (MSM) C1 connector.

    Measure the resistance between ground and the (P152) Telescope Steering Forward/Rearward Position Sense circuit at the Steering Column Telescope Motor connector (harness side).

    Is the resistance below 5.0 ohms? 

    Yes 

    1. Repair the (P152) Telescope Steering Forward/Rearward Position Sense circuit for a short to ground.

    No 

    1. Go to  5).
  5. 5) MEMORY SEAT MODULE (MSM) 

    Inspect the wiring between the Memory Seat Module harness connector and the Steering Column Telescope Motor harness connector for a short to ground or to any other circuit. If any problems are found, repair as necessary. If no problems are found, view repair.

    Repair 

    1. Replace the Memory Seat Module (MSM) in accordance with the Service Information.
  6. 6) INTERMITTENT STEERING COLUMN TELESCOPE POSITION SENSOR CIRCUIT LOW DTC 

    The conditions necessary to set this DTC are not present at this time.

    While monitoring the scan tool data relative to this circuit, wiggle test the component and connectors and move the switch to each position.

    Look for the data to change other than as expected or for the DTC to reset during the wiggle test.

    Were any problems found? 

    Yes 

    1. Repair as necessary.

    No 

    1. Test complete.
