PINPOINT TEST A: U0140:87
NOTE: Most faults are due to connector and/or wiring concerns. Carry out a thorough inspection and verification before proceeding with the pinpoint test.
NOTE: SRS components should only be disconnected or reconnected when instructed to do so within a pinpoint test step. Failure to follow this instruction may result in incorrect diagnosis of the SRS .
NOTE: Always make sure the correct SRS component is being installed. Parts released for other vehicles may not be compatible even if they appear physically similar. Check the part number listed in the Ford parts catalog to make sure the correct component is being installed. If an incorrect SRS component is installed, Diagnostic Trouble Codes (DTCs) may set.
NOTE: The SRS must be fully operational and free of faults before releasing the vehicle to the customer.

A3 CHECK FOR THE CORRECT BECMB (BATTERY ENERGY CONTROL MODULE B)
  • Using the Log Viewer function of the diagnostic scan tool, retrieve and record the BECMB part number.
  • Check the recorded part number against the number listed in the Ford parts catalog.

Does the recorded part number match the number listed in the Ford parts catalog?
Yes GO to A4
No INSTALL the correct BECMB and use As-Built data when carrying out PMI . GO to A6

A4 VERIFY THE BECMB (BATTERY ENERGY CONTROL MODULE B) CONFIGURATION
  • Carry out PMI for the BECMB . Manually enter As-Built data. Refer to the diagnostic scan tool instructions when carrying out PMI .
  • Using a diagnostic scan tool, clear BECMB Diagnostic Trouble Codes (DTCs).
  • Wait 10 seconds.
  • Using a diagnostic scan tool, perform BECMB self-test.

Is DTC U0140:87 retrieved again?
Yes GO to A5
No The system is operating correctly at this time. The DTC was caused by an incorrect BECMB configuration. GO to A6

A5 RETRIEVE THE RECORDED DIAGNOSTIC TROUBLE CODES (DTCS) FROM THE BCM (BODY CONTROL MODULE) SELF-TEST
  • Using a diagnostic scan tool, perform BCM self-test.
  • Check for recorded Diagnostic Trouble Codes (DTCs) from the BCM self-test.

Is DTC U3003:16 or U3003:17 recorded?
Yes DIAGNOSE the BCM Diagnostic Trouble Codes (DTCs).
REFER to: Body Control Module (BCM) (419-10 Multifunction Electronic Modules, Removal and Installation).
No GO to A6

A6 CHECK FOR DTC (DIAGNOSTIC TROUBLE CODE) U0140:00 SET IN OTHER MODULES
  • Ignition ON.
  • Using a diagnostic scan tool, perform self-test for all modules.

Is DTC U0140:00 set in the ABS Module or in the IPC ?
Yes CHECK OASIS for any applicable service articles: TSB , GSB , SSM or FSA . If a service article exists for this concern, DISCONTINUE this test and FOLLOW the service article instructions.
If no service articles address this concern, INSTALL a new BCM. Refer to the appropriate Removal and Installation procedure in Section 419-10.
