1. With the scan tool, read Transmission Control Module (TCM) DTCs and record on the repair order.
2. Record the Environmental Data.
3. With the scan tool, erase DTCs.
4. Using the recorded Environmental Data, along with the When Monitored and Set Conditions above, operate the vehicle in the conditions that set the DTC.
5. With the scan tool, read TCM DTCs.
  Did the DTC return?
  
  Yes
  - Go To 2
  No
  - Perform the TESTING FOR AN INTERMITTENT CONDITION procedure. Refer to TESTING FOR AN INTERMITTENT CONDITION .
CHECK PADDLE SWITCH CIRCUIT FOR AN OPEN
1. Disconnect the TCM harness connector.
2. Measure the resistance of Paddle Switch circuit between the Key Lock Solenoid harness connector and the TCM harness connector.
  Is the resistance below 3.0 Ohms?
  
  Yes
  - Go To 3
  No
  - Repair Paddle Switch circuit for an open or high resistance.
  - Perform the TCM VERIFICATION TEST. Refer to TRANSMISSION VERIFICATION TEST .
CHECK PADDLE SWITCH CIRCUIT FOR A SHORT TO GROUND
1. Check for continuity between ground and Paddle Switch circuit at the TCM harness connector.
  Is there continuity between ground and Paddle Switch circuit?
  
  Yes
  - Repair Paddle Switch circuit for a short to ground.
  - Perform the TCM VERIFICATION TEST. Refer to TRANSMISSION VERIFICATION TEST .
  No
  - Go To 4
CHECK PADDLE SWITCH CIRCUIT FOR STUCK CONTACT
1. Disconnect the Paddle Switch harness connector at the steering wheel.
  Is there continuity between Paddle Switch circuit and any other circuit?
  
  Yes
  - Replace the Paddle Switch Assembly in accordance with the Service Information.
  - Perform the TCM VERIFICATION TEST. Refer to TRANSMISSION VERIFICATION TEST .
  No
  - Go To 5
CHECK RELATED HARNESS CONNECTIONS
1. Disconnect all TCM harness connectors.
2. Disconnect all related in-line harness connections (if equipped).
3. Disconnect the related component harness connectors.
4. Inspect harness connectors, component connectors, and all male and female terminals for the following conditions: Proper connector installation. Damaged connector locks. Corrosion. Other signs of water intrusion. Weather seal damage (if equipped). Bent terminals. Overheating due to a poor connection (terminal may be discolored due to excessive current draw). Terminals that have been pushed back into the connector cavity. Perform a terminal drag test on each connector terminal to verify proper terminal tension. Repair any conditions that are found.
5. Reconnect all TCM harness connectors. Be certain that all harness connectors are fully seated and the connector locks are fully engaged.
6. Reconnect all in-line harness connectors (if equipped). Be certain that all connectors are fully seated and the connector locks are fully engaged.
7. Reconnect all related component harness connectors. Be certain that all connectors are fully seated and the connector locks are fully engaged.
8. With the scan tool, erase DTCs.
9. Using the recorded Event and Environmental Data, along with the When Monitored and Set Conditions above, operate the vehicle in the conditions that set the DTC.
10. With the scan tool, read TCM DTCs.
  Did the DTC return?
  
  Yes
  - Replace the TCM in accordance with the Service Information. Refer to MODULE, TRANSMISSION CONTROL (TCM), REMOVAL AND INSTALLATION .
  - Perform the TCM VERIFICATION TEST. Refer to TRANSMISSION VERIFICATION TEST .
  No
  - Perform the TCM VERIFICATION TEST. Refer to TRANSMISSION VERIFICATION TEST .
  - Test complete.
