1. Turn the ignition off to the lock position.
2. Disconnect the Shift Lever Assembly harness connector.
  NOTE:
  Check connectors - Clean/repair as necessary.
3. Using a 12-volt test light, connect one end to the (Z911) Ground circuit and the other to the (K321) BTSI Control circuit in the Shifter connector.
4. Turn the Ignition on, engine not running.
5. With the scan tool under WIN, select Actuators and actuate the BTSI.
  Does the test light illuminate brightly while the actuator is cycling the (K321) BTSI Control circuit on and off?
  
  Yes
  - Replace the Shift Lever Assembly in accordance with the Service Information.
  - Perform the BODY VERIFICATION TEST. Refer to BODY VERIFICATION TEST for 1500, 2500 & 3500, or BODY VERIFICATION TEST for 3500 CAB & CHASSIS, 4500 & 5500 .
  No
  - With the scan tool, stop the actuation.
  - Go To 3.
