Pinpoint Test A: DTC (Diagnostic Trouble Code) U0100:00

  1. A1 VERIFY THE DIAGNOSTIC SCAN TOOL CAN COMMUNICATE WITH THE POWERTRAIN CONTROL MODULE (PCM) 
    • Connect the diagnostic scan tool.
    • Check that a vehicle session can be established using the diagnostic scan tool.

    Can a vehicle session be established? 

    1. Yes  : GO to A2 
    2. No  : DIAGNOSE the PCM  not communicating with the diagnostic scan tool.

      REFER to: COMMUNICATIONS NETWORK .

  2. A2 CHECK THE BODY CONTROL MODULE (BCM) FOR DIAGNOSTIC TROUBLE CODES (DTCS) 
    • Ignition ON.
    • Using a diagnostic scan tool, perform the BCM  self-test.
    • Clear the Diagnostic Trouble Codes (DTCs).
    • Ignition OFF.
    • Ignition ON.
    • Wait 10 seconds.
    • Repeat the BCM  self-test.

    Is DTC U0100:00 retrieved again? 

    1. Yes  : GO to A3 
    2. 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.
  3. A3 RETRIEVE THE RECORDED DIAGNOSTIC TROUBLE CODES (DTCS) FROM THE POWERTRAIN CONTROL MODULE (PCM) KEY ON ENGINE OFF (KOEO) SELF-TEST 
    • Using a diagnostic scan tool, perform the PCM KOEO  self-test.

    Is DTC P0562 or DTC P0563 recorded? 

    1. Yes  : For vehicles equipped with 2.0L Duratec engine,

      REFER to: ELECTRONIC ENGINE CONTROLS .

      For vehicles equipped with 2.0L EcoBoost, REFER to: ELECTRONIC ENGINE CONTROLS .

    2. No  : GO to A4 
  4. A4 CHECK FOR DTC (DIAGNOSTIC TROUBLE CODE) U0100:00 SET IN OTHER MODULES 
    • Ignition ON.
    • Using a diagnostic scan tool, retrieve all Continuous Memory Diagnostic Trouble Codes (CMDTCs).

    Is DTC U0100:00 set in any other module? 

    1. Yes  : GO to A5 
    2. No  : GO to  A6
  5. A5 CHECK FOR CORRECT POWERTRAIN CONTROL MODULE (PCM) OPERATION 
    • Disconnect and inspect all PCM  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
    • Connect the PCM  connectors. Make sure they seat and latch correctly.
    • Operate the system and determine if the concern is still present.

    Is the concern still present? 

    1. 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 PCM  . For the 2.0L Duratec engine,

      REFER to: POWERTRAIN CONTROL MODULE (PCM) .

      For the 2.0L EcoBoost engine, REFER to: POWERTRAIN CONTROL MODULE (PCM) .

    2. 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.
  6. A6 CHECK FOR CORRECT BODY CONTROL MODULE (BCM) OPERATION 
    • Disconnect and inspect all BCM  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
    • Connect the BCM  connectors. Make sure they seat and latch correctly.
    • Operate the system and determine if the concern is still present.

    Is the concern still present? 

    1. 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 BCM  .

      REFER to: BODY CONTROL MODULE (BCM) .

    2. 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.
