Pinpoint Test At: U0140:00

AT1 VERIFY THE CUSTOMER CONCERN
- Ignition ON.
- Verify there is an observable symptom present.
Is an observable symptom present?
- Yes : GO to AT2
- 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.
AT2 CHECK THE COMMUNICATION NETWORK
- Using a diagnostic scan tool, perform the network test.
Does the BCM pass the network test?
- Yes : GO to AT3
- No : REFER to: COMMUNICATIONS NETWORK .
AT3 PERFORM THE BCM (BODY CONTROL MODULE) SELF-TEST
- Using a diagnostic scan tool, perform the BCM self-test.
Are any Diagnostic Trouble Codes (DTCs) recorded?
- Yes : REFER to: BODY CONTROL MODULE (BCM) .
- No : GO to AT4
AT4 PERFORM THE IPC (INSTRUMENT PANEL CLUSTER) SELF-TEST
- Using a diagnostic scan tool, perform the IPC self-test.
Are any Diagnostic Trouble Codes (DTCs) recorded?
- Yes : REFER to DTC CHART: IPC .
- No : GO to AT5
AT5 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 may be incorrectly set during the Programmable Module Installation (PMI), or the Programmable Module Installation (PMI) may not have been carried out.
- Using a diagnostic scan tool, clear the Diagnostic Trouble Codes (DTCs).
- Wait 10 seconds.
- Repeat the IPC self-test.
Is DTC U0140:00 still present?
- Yes : GO to AT6
- 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.
AT6 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, perform the continuous memory self-test.
- Retrieve the Continuous Memory Diagnostic Trouble Codes (CMDTCs) from all modules.
Is DTC U0140:00 set in the ABS , APIM or RCM ?
- Yes : INSTALL a new BCM .
  REFER to: BODY CONTROL MODULE (BCM) .
- No : INSTALL a new IPC .
  REFER to: INSTRUMENT PANEL CLUSTER (IPC) .
