Pinpoint Test E : B10D9:87

WARNING: This page is about a different car, the 2020 Ford F-150. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may damage the connector.

E1 CHECK FOR DTC (DIAGNOSTIC TROUBLE CODE) C113A:11 OR C113A:15
- Review the results from the BCM self-test.
Is DTC C113A:11 or C113A:15 present?

Yes GO to Pinpoint Test F

No GO to E2

E2 CHECK FOR VOLTAGE TO THE PATS (PASSIVE ANTI-THEFT SYSTEM) TRANSCEIVER

Ignition OFF.

Disconnect: PATS Transceiver C252.

Ignition ON.

Measure:

Positive Lead	Measurement / Action	Negative Lead

Is the voltage greater than 11 volts?

Yes

GO to E5

No	REPAIR the circuit.

E5 CHECK THE LIN (LOCAL INTERCONNECT NETWORK) CIRCUIT FOR A SHORT TO VOLTAGE

Ignition ON.

Disconnect: BCM C2280B.

Measure:

Positive Lead	Measurement / Action	Negative Lead
C252-3	Courtesy of FORD MOTOR COMPANY	Ground

Is any voltage present?

Yes	REPAIR the circuit.

GO to E6

E6 CHECK THE LIN (LOCAL INTERCONNECT NETWORK) CIRCUIT FOR A SHORT TO GROUND

Connect BCM C2280B.

Ignition OFF.

Disconnect: BCM C2280B.

Measure:

Positive Lead	Measurement / Action	Negative Lead
C252-3	Courtesy of FORD MOTOR COMPANY	Ground

Is the resistance greater than 10, 000 ohms?

Yes

GO to E7

No	REPAIR the circuit.

E7 CHECK THE LIN (LOCAL INTERCONNECT NETWORK) CIRCUIT FOR AN OPEN

Measure:

Positive Lead	Measurement / Action	Negative Lead
C252-3	Courtesy of FORD MOTOR COMPANY	C2280B-52

Is the resistance less than 3 ohms?

Yes	INSTALL a new PATS transceiver. REFER to: Passive Anti-Theft System (PATS) Transceiver . CLEAR the Diagnostic Trouble Codes (DTCs) and repeat the BCM self-test. If DTC B10D9:87 is retrieved again, GO to E8

No	REPAIR the circuit.

E8 CHECK FOR CORRECT BCM (BODY CONTROL MODULE) OPERATION

Disconnect and inspect all of the BCM connectors.

Repair:
- corrosion (install new connectors or terminals, clean module pins)
- damaged or bent pins - install new terminals/pins
- pushed-out pins - install new pins as necessary

Reconnect all the BCM connectors and 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, Refer to BCM Guided Routine .

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.
