Diagnostic Test

CHECK IF THE DTC IS ACTIVE
1. With the scan tool, read Transmission DTCs.
  Is the status Active or is the Starts Since Set counter 2 or less for this DTC?
  
  Yes
  - Go to step 2
  No
  - Go to step 5
CHECK FOR FCM/TIPM CAN BUS DTCS
1. With the scan tool, read FCM/TIPM DTCs.
  Are there any FCM/TIPM CAN BUS DTCs present?
  
  Yes
  - Perform CVT VERIFICATION TEST. See DTC-Based Diagnostics/MODULE, Transmission Control (TCM) - Standard Procedure
  No
  - Go to step 3
CHECK IF THE ECM/PCM WAS REPLACED
Was the ECM/PCM replaced?

Yes
- Check to make sure the right part number was used that correlates with the engine and transmission using the vehicle identification number. It may be necessary to flash the ECM/PCM to the proper configuration or replace the controller. With the scan tool perform a TCM relearn procedure.
- Perform CVT VERIFICATION TEST. See DTC-Based Diagnostics/MODULE, Transmission Control (TCM) - Standard Procedure
No
- Go to step 4
CHECK IF THE TCM WAS REPLACED
Was the TCM replaced?

Yes
- Check to make sure the right part number was used that correlates with engine and transmission using the vehicle identification number. It may be necessary to flash the PCM/TCM to the proper configuration or replace the TCM with the correct configuration. With the scan tool perform a TCM relearn procedure.
- Perform CVT VERIFICATION TEST. See DTC-Based Diagnostics/MODULE, Transmission Control (TCM) - Standard Procedure
No
- Using the schematics as a guide, check the Transmission Control Module (TCM) terminals for corrosion, damage, or terminal push out. Pay particular attention to all power and ground circuits. Check for any Service Bulletins for possible causes that may apply. If no problems are found, replace the TCM in accordance with the Service Information.
- Perform CVT VERIFICATION TEST. See DTC-Based Diagnostics/MODULE, Transmission Control (TCM) - Standard Procedure
CHECK THE WIRING AND CONNECTORS
1. The conditions necessary to set this DTC are not present at this time.
2. Using the schematics as a guide, inspect the wiring and connectors specific to this circuit.
3. Wiggle the wires while checking for shorted and open circuits.
  Were there any problems found?
  
  Yes
  - Repair as necessary.
  - Perform CVT VERIFICATION TEST. See DTC-Based Diagnostics/MODULE, Transmission Control (TCM) - Standard Procedure
  No
  - Test Complete.
