- IPMA
- IPC concern
- TR input concern
- A1 CARRY OUT A NETWORK TEST
- Ignition ON.
- Using a diagnostic scan tool, carry out a network test.
Do all modules pass the network test?
Yes GO to A2 No DIAGNOSE any communication concerns. REFER to: ETHERNET MODULE COMMUNICATIONS NETWORK . - A2 CHECK THE IPMA (IMAGE PROCESSING MODULE A) DIAGNOSTIC TROUBLE CODES (DTCS)
- Using the diagnostic scan tool, carry out the IPMA self-test.
Are any parking aid Diagnostic Trouble Codes (DTCs) recorded?
Yes REFER to the appropiate DTC Chart. No GO to A3 - A3 CHECK FOR DIAGNOSTIC TROUBLE CODES (DTCS) FROM THE IPC (INSTRUMENT PANEL CLUSTER) SELF-TEST
- Using the diagnostic scan tool, carry out the IPC self-test.
Are any IPC Diagnostic Trouble Codes (DTCs) recorded?
Yes REFER to: Instrumentation, Message Center and Warning Chimes . No GO to A4 - A4 VERIFY THE PARKING AID IS ENABLED
- Verify the rear parking aid and front parking aid (if equipped) is enabled in the IPC message center.
Is the parking aid system enabled?

- 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
