  - Perform the APS VERIFICATION TEST. Refer to APS VERIFICATION TEST .
CHECK RELATED HARNESS CONNECTIONS
1. Disconnect all MSMD 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.
  - Check for spread terminals and verify proper terminal tension.
  Repair any conditions that are found.
5. Connect all MSMD harness connectors. Be certain that all harness connectors are fully seated and the connector locks are fully engaged.
