  Does this DTC reset and/or remain active?
  
  Yes
  - Go to Step 2.
  No
  - Go to Step 8.
CHECK DTC WITH HARNESS DISCONNECTED
1. Turn the ignition off.
2. Disconnect the Steering Tilt Motor harness connector.
3. Ignition on, engine not running.
4. Move the Steering Column Tilt Switch to the Up and Down positions several times.
5. With the scan tool, select Clear Stored DTCs in the Memory Seat Module.
6. Move the Steering Column Tilt Switch to the Up and Down positions several times, holding the switch in position for at least two seconds each time.
7. With the scan tool, select View DTCs in the Memory Seat Module.
  Does this DTC reset and/or remain active?
  
  Yes
  - Go to Step 3.
  No
  - Thoroughly inspect the wiring and connectors between the Memory Seat Module harness connector and the Steering Tilt Motor for a short to voltage or to any other circuit. If any problems are found, repair as necessary. If no other problems are found, replace the Steering Column Tilt Motor in accordance with the Service Information.
