I3 CHECK FOR CORRECT PAM OPERATION
- Disconnect and inspect all the PAM connectors.
- Repair:
  - corrosion (install new connector or terminals - clean module pins)
  - damaged pins - install new terminals/pins
  - pushed-out pins - install new pins as necessary
- Reconnect the PAM connectors. Make sure they seat and latch correctly.
- Operate the system and determine if the concern is still present.
- Is the concern still present?
- Yes : CHECK OASIS for any applicable TSBs. If a TSB exists for this concern, DISCONTINUE this test and FOLLOW TSB instructions. If no TSBs address this concern, INSTALL a new PAM. REFER to PARKING AID - AUDIBLE .
- 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.
