Diagnostic Test

CHECK THE VEHICLE CONFIGURATION
NOTE:
The DTC must be active and no BUS communication DTCs present before performing this test. If BUS communication DTCs are present, perform there respective test first. If the DTC is stored, erase the DTC and cycle the ignition. If the DTC resets and changes to active, then proceed.
1. With the scan tool, check the vehicle configuration stored in the Body Control Module (BCM).
2. With the scan tool, check the vehicle configuration stored in the Memory Seat Module-Driver (MSMD).
  Pick the answer that best describes your findings:
  
  BCM has wrong or no vehicle configuration .
  - With the scan tool, program the proper vehicle configuration in the BCM.
  - Perform the POWER SEAT SYSTEM VERIFICATION TEST. Refer to POWER SEAT SYSTEM VERIFICATION TEST .
  MSMD has wrong vehicle configuration but BCM has the correct configuration .
  - Go To 2
  MSMD and BCM have proper calibration and the DTC is active in the HVAC .
  - Check if other modules, such as the Powertrain Control Module (PCM), have the wrong configuration stored in the controller and reprogram or replace as necessary. If all other modules show the proper configuration Go To 2
  - Perform the POWER SEAT SYSTEM VERIFICATION TEST. Refer to POWER SEAT SYSTEM VERIFICATION TEST .
CHECK RELATED HARNESS CONNECTIONS
1. Turn the ignition off.
2. Disconnect all MSMD harness connectors.
3. Disconnect all related in-line harness connections (if equipped).
4. Disconnect the related component harness connectors.
5. 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.
6. Reconnect all MSMD harness connectors. Be certain that all harness connectors are fully seated and the connector locks are fully engaged.
7. Reconnect all in-line harness connectors (if equipped). Be certain that all connectors are fully seated and the connector locks are fully engaged.
8. Reconnect all related component harness connectors. Be certain that all connectors are fully seated and the connector locks are fully engaged.
9. With the scan tool, erase DTCs.
10. Using the recorded Environmental Data, along with the When Monitored and Set Conditions above, operate the vehicle in the conditions that set the DTC.
11. With the scan tool, read MSMD DTCs.
  Did the DTC return?
  
  Yes
  - Replace and program the Memory Seat Module-Driver (MSMD) in accordance with the Service Information. Refer to MODULE, MEMORY, SEAT (MSM), REMOVAL AND INSTALLATION .
  - Perform the POWER SEAT SYSTEM VERIFICATION TEST. Refer to POWER SEAT SYSTEM VERIFICATION TEST .
  No
  - Perform the POWER SEAT SYSTEM VERIFICATION TEST. Refer to POWER SEAT SYSTEM VERIFICATION TEST .
  - Test complete.
