Pinpoint Test C: DTC B10D9:87

WARNING: This page is about a different car, the 2011 Ford Pickup, 2011 Ford F550 Super Duty, 2011 Ford F450 Super Duty, and 2011 Ford Cab & Chassis. 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.
  1. C1 RETRIEVE THE BCM DTCs FROM THE SELF-TEST 
    • Check the recorded results from the BCM  self-test.
    • Is DTC C113A:11 or DTC C113A:15 recorded? 
  2. C2 CHECK FOR VOLTAGE TO THE PATS TRANSCEIVER 
    • Disconnect: PATS  Transceiver C252.
    • Ignition ON.
    • Measure the voltage between the PATS  transceiver C252-1, circuit CE436 (VT/OG), harness side and the PATS  transceiver C252-2, circuit GD184 (BK/GY or BK/YE).

    • Is the voltage greater than 10 volts? 
    • Yes:  GO to  C4.
    • No:  GO to  C3.
  3. C3 CHECK THE PATS TRANSCEIVER VOLTAGE SUPPLY CIRCUIT 
    • Measure the voltage between the PATS  transceiver C252-1, circuit CE436 (VT/OG), harness side and ground.

    • Is the voltage greater than 10 volts? 
    • Yes:  REPAIR circuit GD184 (BK/GY or BK/YE) for an open. CLEAR the DTCs. REPEAT the self-test.
    • No:  VERIFY the BCM  fuse 18 (10A) is OK. If OK, REPAIR circuit CE436 (VT/OG) for an open. If not OK, REFER to the appropriate System Wiring Diagrams article to identify the possible causes of the circuit short. CLEAR the DTCs. REPEAT the self-test.
  4. C4 CHECK THE PATS TRANSCEIVER CIRCUITS FOR A SHORT TO VOLTAGE 
    • Ignition OFF.
    • Disconnect: BCM  C2280B.
    • Ignition ON.
    • Measure the voltage between the PATS  transceiver C252-3, circuit VRT23 (VT/GY), harness side and ground; and between the PATS  transceiver C252-4, circuit VRT24 (YE/OG), harness side and ground.

    • Is any voltage present? 
    • Yes:  REPAIR the circuit in question for a short to voltage. CLEAR the DTCs. REPEAT the self-test.
    • No:  GO to  C5.
  5. C5 CHECK THE PATS TRANSCEIVER CIRCUITS FOR A SHORT TO GROUND 
    • Ignition OFF.
    • Measure the resistance between the PATS  transceiver C252-3, circuit VRT23 (VT/GY), harness side and ground; and between the PATS  transceiver C252-4, circuit VRT24 (YE/OG), harness side and ground.

    • Are the resistances greater than 10,000 ohms? 
    • Yes:  GO to  C6.
    • No:  REPAIR the circuit in question for a short to ground. CLEAR the DTCs. REPEAT the self-test.
  6. C6 CHECK THE PATS TRANSCEIVER CIRCUITS FOR AN OPEN 
    • Measure the resistance between the BCM  , harness side and the PATS  transceiver, harness side as follows:

    • Are the resistances less than 5 ohms? 
    • Yes:  INSTALL a new PATS  transceiver. REFER to PASSIVE ANTI-THEFT SYSTEM (PATS) TRANSCEIVER .. CLEAR the DTCs. REPEAT the self-test. If DTC B10D9:87 is retrieved again, GO to  C7.
    • No:  REPAIR the circuit in question for an open. CLEAR the DTCs. REPEAT the self-test.
  7. C7 CHECK FOR CORRECT BCM OPERATION 
    • Disconnect the BCM  connectors.
    • Check for:
      • corrosion
      • damaged pins
      • pushed-out pins
    • Connect the BCM  connectors and make sure it seats correctly.
    • Operate the system and verify the concern is still present.
    • Is the concern still present? 
    • Yes:  INSTALL a new BCM  . REFER to MULTIFUNCTION ELECTRONIC MODULE . TEST the system for normal operation.
    • No:  The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector.
