Diagnostic Test

VERIFY THE DTC IS ACTIVE
1. Turn the Ignition ON.
2. With the scan tool, record and erase the DTCs.
3. Cycle the ignition switch from off to on.
4. With the scan tool, read the DTCs.
  Is the DTC active at this time?
  
  Yes
  - Go To 2
  No
  - Go To 3
CHECK IF Antilock Brake System (ABS) DTCS ARE PRESENT
1. With the scan tool, read the ABS DTCs.
  Are there any ABS DTCs present?
  
  Yes
  - Perform the appropriate diagnostic procedure. Refer to DIAGNOSTIC CODE INDEX .
  No
  
  NOTE:
  If this Electronic Control Unit (ECU) is being replaced with a new unit, a diagnostic scan tool MUST be used to align the PROXI configuration data into the new ECU. Follow the routine outlined in the diagnostic scan tool for PROXI Configuration Alignment under Body Control Module (BCM) Miscellaneous Functions menu.
  - Using the schematics as a guide, check the Transmission Control Module (TCM) terminals and connectors for corrosion, damage or pushed out terminals. Pay particular attention to the power and ground circuits. If no problems are found, replace the TCM and perform programming and PROXI Configuration Alignment procedures. Refer to MODULE, TRANSMISSION CONTROL, REMOVAL .
  - Perform the TRANSMISSION VERIFICATION TEST. Refer to STANDARD PROCEDURE .
INTERMITTENT WIRING AND CONNECTORS
1. Using the wiring diagram/schematic as a guide, inspect the wiring harness and connectors.
2. Wiggle test the wiring harness and connectors while monitoring the scan tool data relative to this circuit.
3. Look for the data to change or for the DTC to reset during the wiggle test.
4. While monitoring the scan tool data relative to this circuit, move the selector switch to each position several times.
5. Look for the data to change other than as expected or for the DTC to reset.
  Were any problems found?
  
  Yes
  - Repair as necessary.
  - Perform the TRANSMISSION VERIFICATION TEST. Refer to STANDARD PROCEDURE .
  No
  - Test complete, the condition or conditions that originally set this DTC are not present at this time.
