- A1 PERFORM A NETWORK TEST
- Ignition ON
- Using a diagnostic scan tool, perform a network test REFER to: Communications Network .
Do all modules pass the network test?
Yes GO to A2 No Diagnose any communication concerns. Refer to: Communications Network . - A2 CHECK THE PAM (PARKING ASSIST CONTROL MODULE) DIAGNOSTIC TROUBLE CODES (DTCS)
- Using a diagnostic scan tool, perform the PAM self-test.
Are any PAM Diagnostic Trouble Codes (DTCs) recorded?
Yes REFER to the DTC Chart in this article. No GO to A3 - A3 CHECK THE DIAGNOSTIC TROUBLE CODES FROM THE IPC (INSTRUMENT PANEL CLUSTER)
- Using a diagnostic scan-tool, perform the IPC self-test.
Are any IPC Diagnostic Trouble Codes (DTCs) Recorded?
Yes DIAGNOSE any IPC Diagnostic Trouble Codes (DTCs). Refer to: Instrumentation, Message Center And Warning Chimes . No GO to A4 - A4 VERIFY THE PARKING AID IS ENABLED
- Verify the park aid is enabled in the IPC message center.
Is the park aid system enabled?

- Apply the parking brake.
- Ignition ON.
- Select REVERSE.
- Using a diagnostic scan tool, view the IPC Parameter Identifications (PIDs).
- Monitor the IPC transmission gear display PID (GEAR_DISP).
Does the PID match the gearshift selector position?
Yes GO to A6 No DIAGNOSE the TR sensor. Refer to: External Controls - Overview . - A6 CHECK FOR CORRECT PAM (PARKING ASSIST CONTROL MODULE) OPERATION
- Ignition OFF.
- Disconnect and inspect all PAM and related in-line connectors.
- 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 PAM and related in-line connectors. Make sure they seat and latch correctly.
- Operate the system and determine if the concern is still present.
Is the concern still present?
