RETRIEVE THE Diagnostic Trouble Codes (DTCs) FROM THE Parking Aid Module (PAM) SELF-TEST
1. Check the Parking Aid Module (PAM) Diagnostic Trouble Codes (DTCs) from the self-test.
- Are multiple Diagnostic Trouble Codes (DTCs) recorded?
- Yes: GO to 2 on page 2.
- No: GO to 3 on page 2.
CHECK THE CONNECTORS FOR CORRECT LATCHING AND THE BUMPER WIRING HARNESS FOR DAMAGE
1. Inspect the Parking Aid Module (PAM) and sensor connectors for correct latching by pulling on the latched connector.
2. Inspect the bumper wiring harness for opens, shorts or corrosion.
- Are the connectors correctly latched and the bumper wiring harness OK?
- Yes: GO to 3 on page 2.
- No: Correctly LATCH the connectors or REPAIR or INSTALL a new bumper wiring harness.

- Is the resistance greater than 10,000 ohms?
- Yes: INSTALL a new sensor(s) for the sensor(s) in question. REFER to Parking Aid Sensor . CLEAR the Diagnostic Trouble Codes (DTCs). REPEAT the Parking Aid Module (PAM) self-test.
  If the Diagnostic Trouble Code (DTC) returns, GO to 5 on page 3.
- No: REPAIR the circuits in question.
CHECK FOR CORRECT Parking Aid Module (PAM) OPERATION

Disconnect and inspect the Parking Aid Module (PAM) connector.
Repair:
- corrosion (install new connector or terminals - clean module pins)
- damaged or bent pins - install new terminals/pins
- pushed-out pins - install new pins as necessary
Reconnect the Parking Aid Module (PAM) connector. Make sure it seats and latches correctly.
Operate the system and determine if the concern is still present.

Is the concern still present?

Yes: CHECK On-Line Automotive Service Information System (OASIS) for any applicable Technical Service Bulletins (TSBs). If a Technical Service Bulletin (TSB) exists for this concern, DISCONTINUE this test and FOLLOW Technical Service Bulletin (TSB) instructions. If no Technical Service Bulletins (TSBs) address this concern, INSTALL a new Parking Aid Module (PAM). REFER to PARKING AID MODULE (PAM) .
No: The system is operating correctly at this time. The concern may have been caused by module connections. ADDRESS the root cause of any connector or pin issues.
