Pinpoint Test A : DTC (Diagnostic Trouble Code) B10E5:11 Or DTC (Diagnostic Trouble Code) B10E5:15

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.

A1 CHECK FOR BCM (BODY CONTROL MODULE) DIAGNOSTIC TROUBLE CODES (DTCS)

Ignition ON.

Using a diagnostic scan tool, perform BCM self-test.

Is DTC B10E5:11 present?

Yes

GO to A2

No	If DTC B10E5:15 is present, GO to A5 For all other BCM Diagnostic Trouble Codes (DTCs), REFER to the BCM DTC Chart .

A2 CHECK THE PCM (POWERTRAIN CONTROL MODULE) FOR A SHORT TO GROUND
- Ignition OFF.
- Disconnect: PCM C175B .
- Ignition ON.
- Using a diagnostic scan tool, clear BCM Continuous Memory Diagnostic Trouble Codes (CMDTCs).
- Wait 10 seconds.
- Using a diagnostic scan tool, perform BCM self-test.
Is DTC B10E5:11 present?

Yes GO to A3

No GO to A8

A3 CHECK THE SOBDMC (HYBRID POWERTRAIN CONTROL MODULE) / TCM (TRANSMISSION CONTROL MODULE) FOR A SHORT TO GROUND
- Ignition OFF.
- Disconnect: SOBDMC/ TCM C1458A .
- Ignition ON.
- Using a diagnostic scan tool, clear BCM Continuous Memory Diagnostic Trouble Codes (CMDTCs).
- Wait 10 seconds.
- Using a diagnostic scan tool, perform BCM self-test.
Is DTC B10E5:11 present?

Yes GO to A4

No GO to A9

Is the resistance less than 3 ohms?

Yes

GO to A7

No	REPAIR the circuit in question.

A7 CHECK FOR CORRECT BCM (BODY CONTROL MODULE) 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

Reconnect 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?

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) .

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.

A8 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.

A9 CHECK FOR CORRECT SOBDMC (HYBRID POWERTRAIN CONTROL MODULE) / TCM (TRANSMISSION CONTROL MODULE) OPERATION

Ignition OFF.

Disconnect and inspect all SOBDMC/ TCM 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 SOBDMC/ TCM 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 SOBDMC/ TCM. REFER to: Transmission Control Module (TCM) .

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.
