WARNING: This page is about a different car, the 2015 Ford C-Max. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
If new modules were installed prior to the DTC being set, the module configuration may be incorrectly set during the PMI or the PMI may not have been carried out.
- B1 VERIFY THE DIAGNOSTIC SCAN TOOL CAN COMMUNICATE WITH THE PCM (POWERTRAIN CONTROL MODULE)
- Connect the diagnostic scan tool.
- Check that a vehicle session can be established using the diagnostic scan tool.
Can a vehicle session be established?
Yes GO to B2 No DIAGNOSE the PCM not communicating with the diagnostic scan tool. REFER to: Communications Network . - B2 CHECK THE BCM (BODY CONTROL MODULE) 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?
Yes GO to B3 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. - B3 RETRIEVE THE RECORDED DIAGNOSTIC TROUBLE CODES (DTCS) FROM THE PCM (POWERTRAIN CONTROL MODULE) KOEO (KEY ON, ENGINE OFF) SELF-TEST
- Using a diagnostic scan tool, perform the PCM KOEO self-test.
Is DTC P0562 or DTC P0563 recorded?
Yes REFER to: ELECTRONIC ENGINE CONTROLS - PLUG-IN HYBRID ELECTRIC VEHICLE (PHEV) . No GO to B4 - B4 CHECK THE GWM (GATEWAY MODULE A) DIAGNOSTIC TROUBLE CODES (DTCS)
- Using a diagnostic scan tool, check the GWM Diagnostic Trouble Codes (DTCs).
Are any Diagnostic Trouble Codes (DTCs) recorded?
Yes REFER to: Communications Network . No GO to B5 - B5 CHECK FOR DTC (DIAGNOSTIC TROUBLE CODE) U0100 SET IN OTHER MODULES
- Ignition ON.
- Using a diagnostic scan tool, retrieve all Diagnostic Trouble Codes (DTCs).
Is DTC U0100 set in any other module?
Yes GO to B6 No GO to B7 - B6 CHECK FOR CORRECT PCM (POWERTRAIN CONTROL MODULE) OPERATION
- Ignition OFF.
- 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
- Reconnect 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?
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. REFER to: POWERTRAIN CONTROL MODULE (PCM) . 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. - B7 CHECK FOR CORRECT BCM (BODY CONTROL MODULE) OPERATION
- Ignition OFF.
- 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
