Pinpoint Test H : U0140:87
- H1 VERIFY THE CUSTOMER CONCERN
- Ignition ON.
- Verify that there is an observable symptom present.
Is an observable symptom present?
Yes GO to H2 No Clear the DTC The system is operating normally at this time. The DTC may have been set due to high network traffic or an intermittent fault condition. - H2 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 H4 No DIAGNOSE no communication with the BCM. Refer to: Communications Network . - H3 RETRIEVE THE RECORDED DIAGNOSTIC TROUBLE CODES (DTCS) FROM THE BCM (BODY CONTROL MODULE) CONTROL MODULE SELF-TEST
- Using a diagnostic scan tool, perform the BCM control module self-test.
Are any Diagnostic Trouble Codes (DTCs) present?
Yes REFER to: Body Control Module (BCM) . No GO to H4 - H4 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 the system for normal operation.
- Using a diagnostic scan tool, repeat the PAM self-test.
Is DTC U0140:87 still present?
Yes GO to H5 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. - H5 CHECK FOR BATTERY VOLTAGE OUT OF RANGE DIAGNOSTIC TROUBLE CODES (DTCS)
- Using a diagnostic scan tool, retrieve the Continuous Memory Diagnostic Trouble Codes (DTCs) from all modules.
Is DTC U3003:62 set in the PAM?
Yes GO to Pinpoint Test I No GO to H6 - H6 CHECK FOR DIAGNOSTIC TROUBLE CODE (DTC) U0140:00 OR DIAGNOSTIC TROUBLE CODE (DTC) U0140:87 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 U0140:00 or DTC U0140:87 set in any other module?
Yes GO to H7 No GO to H8 - H7 CHECK FOR CORRECT BCM (BODY CONTROL MODULE) OPERATION
- Ignition OFF.
- Disconnect and inspect all BCM 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 BCM 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 BCM. Refer to: Body Control Module (BCM) . 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. - H8 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

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) - 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.
