Pinpoint Test Ac: U0140:00: U0140:00

AC1 VERIFY THE CUSTOMER CONCERN
- Ignition ON.
- Verify there is an observable symptom present.
Is an observable symptom present?
- Yes : GO to AC2
- 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.
AC2 CHECK THE COMMUNICATION NETWORK
- Using a diagnostic scan tool, perform a network test.
Does the BCM pass the network test?
- Yes : GO to AC3
- No : REFER to: COMMUNICATIONS NETWORK .
AC3 CHECK FOR BCM (BODY CONTROL MODULE) DIAGNOSTIC TROUBLE CODES (DTCS)
- Using a diagnostic scan tool, perform the BCM self-test.
Are any voltage related Diagnostic Trouble Codes (DTCs) present?
- Yes : REFER to: BODY CONTROL MODULE (BCM) .
- No : GO to AC4
AC4 RECHECK THE DDM (DRIVER DOOR MODULE) OR PDM (PASSENGER DOOR MODULE) DIAGNOSTIC TROUBLE CODES (DTCS)
NOTE: If new modules were installed prior to the DTC being set, the module configuration may be incorrectly set during PMI or the PMI may not have been performed.
- Using a diagnostic scan tool, clear the Diagnostic Trouble Codes (DTCs) and repeat the DDM /PDM self-test.
Is DTC U0140:00 still present?
- Yes : GO to AC5
- 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.
AC5 CHECK FOR DTC (DIAGNOSTIC TROUBLE CODE) U0140 SET IN OTHER MODULES
- Using a diagnostic scan tool, clear all Diagnostic Trouble Codes (DTCs).
- Ignition OFF.
- Ignition ON.
- Wait 30 seconds.
- Using a diagnostic scan tool, retrieve the Continuous Memory Diagnostic Trouble Codes (CMDTCs) from all modules.
Is DTC U0140 set in other modules?
- Yes : INSTALL a new BCM .
  REFER to: BODY CONTROL MODULE (BCM) .
- No : INSTALL a new DDM or PDM . For the DDM ,
  REFER to: DRIVER DOOR MODULE (DDM) .
  
  For a PDM ,
  
  REFER to: PASSENGER DOOR MODULE (PDM) .
