Pinpoint Test O : U0140
- O1 VERIFY THE CUSTOMER CONCERN
- Ignition ON
- Verify that there is an observable symptom present.
Is an observable symptom present?
Yes GO to O2 No The system is operating correctly at this time. The DTC may have been set due to high network traffic or an intermittent fault condition. - O2 CHECK THE COMMUNICATION NETWORK
- Ignition ON.
- Using a diagnostic scan tool, perform the network test REFER to: Communications Network . .
Does the BCM pass the network test?
Yes GO to O3 No Diagnose the no communication with the BCM REFER to: Communications Network . - O3 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
Are any Diagnostic Trouble Codes (DTCs) present?
Yes REFER to: Remote Function Actuator (RFA) Module . No GO to O4 - O4 RECHECK THE PAM (PARKING ASSIST CONTROL MODULE) DIAGNOSTIC TROUBLE CODES (DTCS)
- Ignition OFF.
- Using a diagnostic scan tool, clear the Diagnostic Trouble Codes (DTCs).
- Operate the system and test for normal operation.
- Check the PAM continuous memory Diagnostic Trouble Codes (DTCs).
Is DTC U0140 still present?
Yes GO to O5 No The system is operating correctly at this time. The DTC may have been set due to high network traffic or an intermittent fault condition. - O5 CHECK FOR DTC (DIAGNOSTIC TROUBLE CODE) U0140 IN OTHER MODULES
- Using a diagnostic scan tool, clear all Diagnostic Trouble Codes (DTCs).
- Ignition OFF.
- Wait 10 seconds.
- Ignition ON.
- Wait 10 seconds.
- Using a diagnostic scan tool, retrieve the continuous memory Diagnostic Trouble Codes (DTCs) from all modules.
Is DTC U0140 set in other modules?
Yes Refer to BCM GUIDED ROUTINE TESTING No GO to O6 - O6 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?
Yes CHECK OASIS for any applicable Technical Service Bulletins (TSBs). If a TSB exists for this concern, DISCONTINUE this test and FOLLOW the TSB instructions. If no TSB addresses this concern, INSTALL a new PAM. REFER to: Parking Assist Control Module (PAM) - 4-Door . REFER to: Parking Assist Control Module (PAM) - 5-Door . No The system is operating correctly at this time. Concern may have been caused by a loose or corroded connector. ADDRESS the root cause of any connector or pin issues.
