CHECK FOR AN ACTIVE DTC
1. With the scan tool, read Transmission Control Module (TCM) DTCs and record on the repair order.
2. Record the Event Data and Environmental Data.
3. With the scan tool, erase DTCs.
4. 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.
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 FOR OTHER SENSOR DTCS
1. With the scan tool, read TCM DTCs.
  Are there other sensor or sensor power supply DTCs set?
  
  Yes
  - Check the (F893) 5 Volt Supply A circuit for an open or short to ground. If no problem is found, Go To 5.
  - Perform the TRANSMISSION VERIFICATION TEST. Refer to C635 DDCT TRANSMISSION VERIFICATION TEST .
  No
  - Go To 3
CHECK THE (T4) 5-R POSITION SIGNAL CIRCUIT FOR AN OPEN OR SHORT TO GROUND
1. Turn the ignition off.
2. Disconnect the TCM C2 harness connector.
3. Disconnect the 5-R Position Sensor harness connector.
4. Check the (T4) 5-R Position Signal circuit for an open or short to ground.
  Was an open or short to ground found?
  
  Yes
  - Repair the (T4) 5-R Position Signal circuit for an open or short to ground.
  - Perform the TRANSMISSION VERIFICATION TEST. Refer to C635 DDCT TRANSMISSION VERIFICATION TEST .
  No
  - Go To 4
CHECK THE (T191 AND T192) SENSOR GROUND CIRCUIT FOR AN OPEN
1. Measure the resistance of the (T191 AND T192) Sensor Ground circuit between the 5-R Position Sensor and the TCM C2 harness connector.
  Is the resistance below 3.0 Ohms?
  
  Yes
  - Replace the 5-R Position Sensor.
  - Perform the TRANSMISSION VERIFICATION TEST. Refer to C635 DDCT TRANSMISSION VERIFICATION TEST .
  No
  - Repair the (T191 or T192) Sensor Ground circuit for an open.
  - Perform the TRANSMISSION VERIFICATION TEST. Refer to C635 DDCT TRANSMISSION VERIFICATION TEST .
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, REMOVAL AND INSTALLATION .
  - Perform the TRANSMISSION VERIFICATION TEST. Refer to C635 DDCT TRANSMISSION VERIFICATION TEST .
  No
  - Perform the TRANSMISSION VERIFICATION TEST. Refer to C635 DDCT TRANSMISSION VERIFICATION TEST .
  - Test complete.
