Pinpoint Test Ax: U0140:00

AX1 VERIFY THE CUSTOMER CONCERN
- Ignition ON.
- Verify there is an observable symptom present.
Is an observable symptom present?
- Yes : GO to AX2
- 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. CLEAR the DTC .
AX2 CHECK THE COMMUNICATION NETWORK
- Using a diagnostic scan tool, perform a Network Test.
Does the BCM pass the network test?
- Yes : GO to AX3
- No : Refer to: COMMUNICATIONS NETWORK .
AX3 RETRIEVE THE RECORDED DIAGNOSTIC TROUBLE CODES (DTCS) FROM THE BCM (BODY CONTROL MODULE) SELF-TEST
- Using a diagnostic scan tool, perform the BCM module self-test.
Are any Diagnostic Trouble Codes (DTCs) recorded?
- Yes : Refer to: BODY CONTROL MODULE (BCM) .
- No : GO to AX4
AX4 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 AX5
AX5 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 U0140:00 still present?
- Yes : GO to AX6
- 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. CLEAR the DTC .
AX6 CHECK FOR DTC (DIAGNOSTIC TROUBLE CODE) U0140:00 SET IN OTHER MODULES
- Using a diagnostic scan tool, clear all Diagnostic Trouble Codes (DTCs).
- Ignition OFF.
- Ignition ON.
- Wait 10 seconds.
- Using a diagnostic scan tool, retrieve all continuous memory Diagnostic Trouble Codes (DTCs).
Is DTC U0140:00 set in other modules on the network?
- Yes : REFER to THE BCM DOES NOT RESPOND TO THE DIAGNOSTIC SCAN TOOL to DIAGNOSE the CAN circuits.
  Refer to: COMMUNICATIONS NETWORK .
- No : GO to AX7
AX7 CHECK FOR CORRECT IPC (INSTRUMENT PANEL CLUSTER) OPERATION
- Ignition OFF.
- Disconnect and inspect the IPC connector.
- 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 IPC connector. Make sure it seats and latches correctly.
- Operate the system and verify 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 TSB instructions. If no Technical Service Bulletins (TSBs) address this concern, INSTALL a new IPC .
  Refer to: INSTRUMENT PANEL CLUSTER (IPC) .
- No : The system is operating correctly at this time. The concern may have been caused by module connections. ADDRESS the root cause of any connector or pin issues.
