- AZ1 VERIFY THE CUSTOMER CONCERN
- Ignition ON.
- Verify there is an observable symptom present.
Is an observable symptom present?
Yes GO to AZ2 No The system is operating normally at this time. The DTC may have been set due to high network traffic or an intermittent fault condition. - AZ2 CHECK THE COMMUNICATION NETWORK
- Using a diagnostic scan tool, perform a network test.
Does the PAM pass the network test?
Yes GO to AZ3 No REFER to: Communications Network . - AZ3 RETRIEVE THE RECORDED DIAGNOSTIC TROUBLE CODES (DTCS) FROM THE BCM (BODY CONTROL MODULE) SELF-TEST
- Using a diagnostic scan tool, perform the BCM self-test.
Is DTC U0159:00 recorded?
Yes REFER to: Body Control Module (BCM) . No GO to AZ4 - AZ4 RETRIEVE THE RECORDED DIAGNOSTIC TROUBLE CODES (DTCS) FROM THE IPC (INSTRUMENT PANEL CLUSTER) SELF-TEST
- Using a diagnostic scan tool, perform the IPC self-test.
Is DTC U3006:16 or DTC U3006:17 recorded?
Yes REFER to DTC Chart: IPC . No GO to AZ5 - AZ5 RETRIEVE THE RECORDED DIAGNOSTIC TROUBLE CODES (DTCS) FROM THE PAM (PARKING ASSIST CONTROL MODULE) SELF-TEST
- Using a diagnostic scan tool, perform the PAM self-test.
Are any Diagnostic Trouble Codes (DTCs) recorded?
Yes Refer to the appropriate Instrumentation and Warning Systems article for the procedure. No GO to AZ6 - AZ6 RECHECK THE IPC (INSTRUMENT PANEL CLUSTER) DIAGNOSTIC TROUBLE CODES (DTCS)NOTE: If new modules were installed prior to the DTC being set, the module configuration can be incorrectly set during the PMI or the PMI may not have been carried out.
- Using a diagnostic scan tool clear the Diagnostic Trouble Codes (DTCs).
- Wait 10 seconds.
- Using a diagnostic scan tool, perform the IPC self-test.
Is DTC U0159:00 still present?
Yes GO to AZ7 No The system is operating normally at this time. The DTC may have been set due to high network traffic or an intermittent fault condition. - AZ7 CHECK FOR CORRECT PAM (PARKING ASSIST CONTROL MODULE) OPERATION
- Ignition OFF.
- Disconnect and inspect all PAM 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
