Pinpoint Test D: B10D9:87

Diagnostic Overview

Diagnostics in this manual assume a certain skill level and knowledge of Ford-specific diagnostic practices. Refer to Diagnostic Methods in Section 100-00 for information about these practices.

Refer to Wiring Diagrams Cell 112 , Passive Anti-Theft System for schematic and connector information.

Normal Operation and Fault Conditions

The BCM supplies voltage to the PATS transceiver. When the ignition changes to RUN or START, the BCM initiates the key interrogation sequence. The BCM starts the interrogation sequence by generating a signal and sending that signal to the transceiver on the transmit (TX) circuit. When the transceiver receives the signal from the BCM , it reads the PATS key and generates a challenge response to the BCM signal. The transceiver sends the challenge response back to the BCM on the receive (RX) circuit.

BCM DTC Fault Trigger Conditions

DTC	Description	Fault Trigger Conditions
B10D9:87	PATS Transponder: Missing Message	Sets when the BCM does not receive a response from the PATS transceiver.

Possible Sources:

Visual Inspection and Diagnostic Pre-checks

Verify the BCM fuse 18 (10A) is OK.

PINPOINT TEST D: B10D9:87

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

Diagnostic Overview

Diagnostics in this manual assume a certain skill level and knowledge of Ford-specific diagnostic practices. Refer to Diagnostic Methods in Section 100-00 for information about these practices.

Refer to Wiring Diagrams Cell 112 , Passive Anti-Theft System for schematic and connector information.

Normal Operation and Fault Conditions

The wakeup control circuit wakes up the PCM prior to engine cranking. The PCM needs to wake up prior to a crank request so that it has time to go through its initialization. The wakeup control circuit also powers the PATS transceiver. The wakeup control circuit is controlled by the BCM . The wakeup control circuit is FET protected.

The BCM activates the wakeup control circuit when:

the driver door is opened,
a remote start request is received (if equipped with factory remote start),
the brake pedal is applied,
a key is inserted into the ignition key cylinder, or
the ignition is in RUN or START.
