2. With the scan tool, check the vehicle configuration stored in the Memory Seat Module (MSMP).
  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 .
  MSMP has wrong vehicle configuration but BCM has the correct configuration.
  - Go To 2
  MSMP 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 MSMP harness connectors.
3. Disconnect all related in-line harness connections (if equipped).
4. Disconnect the related component harness connectors.

  - 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 MSMP 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.
