Pinpoint Test A: DTC B11E8:16

WARNING: This page is about a different car, the 2013 Ford Mustang. 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
NOTE: Failure to disconnect the battery when instructed results in false resistance readings. Refer to BATTERY, MOUNTING AND CABLES .
  1. A1 RECHECK THE ABS MODULE DTCs 
    • Ignition ON.
    • Enter the following diagnostic mode on the scan tool: ABS Module Self-Test.
    • Clear the DTCs.
    • Wait 10 seconds.
    • Repeat the ABS module self-test.
    • Is DTC B11E8:16 still present? 
    • Yes  : GO to A2.
    • No  : The system is operating correctly at this time. The DTC may have been set due to a previous low battery voltage condition.
  2. A2 CHECK FOR CHARGING SYSTEM DTCs IN THE PCM 
    • Enter the following diagnostic mode on the scan tool: PCM Self-Test.
    • Carry out the PCM Key ON Engine OFF (KOEO) self-test.
    • Is DTC P0620, P0625, P0626 or P065B set in the PCM? 
  3. A3 CHECK THE BATTERY CONDITION AND STATE OF CHARGE 
    • Check the battery condition and verify the battery is fully charged. Refer to BATTERY, MOUNTING AND CABLES .
    • Is the battery OK and fully charged? 
  4. A4 CHECK THE ABS MODULE VOLTAGE SUPPLY 
    • Ignition OFF.
    • Disconnect: ABS Module C135.
    • Ignition ON.
    • Measure and record the voltage at the battery.
    • Measure the voltage between the ABS module C135 and ground as follows:
      ABS Module Connector-Pin Circuit
      C135-1 SBB08 (VT/RD)
      C135-25 SBB10 (YE/RD)
      C135-30 CBP34 (VT/BN)

    • Are the voltages within 0.2 volt of the recorded battery voltage? 
    • Yes  : GO to A5.
    • No  : VERIFY the fuses are OK. If OK, REPAIR the circuit in question for an open. If not OK, REFER to the OEM WIRING DIAGRAMS to identify the possible causes of the short circuit. CLEAR the DTC. REPEAT the self-test.
  5. A5 CHECK THE ABS MODULE GROUND CIRCUIT 
    • Ignition OFF.
    • Disconnect: Negative Battery Cable.
    • Measure the resistance between the ABS module C135-13, circuit GD120 (BK/GN), harness side and ground; and between the ABS module C135-38, circuit GD120 (BK/GN), harness side and ground.

    • Is the resistance less than 5 ohms? 
    • Yes  : GO to A6.
    • No  : REPAIR circuit GD120 (BK/GN) for open circuit.

      CLEAR the DTCs. REPEAT the self-test.

  6. A6 CHECK THE ABS MODULE GROUND EYELET AT THE CHASSIS 
    • Ignition OFF.
    • Remove the bolt retaining G101, engine compartment, LH side front.
      • Clean the body mating surface and ground eyelets.
      • Install the ground eyelet to the chassis with the retaining bolt.
    • Ignition ON.
    • Enter the following diagnostic mode on the scan tool: ABS Module Self-Test.
    • Is the concern still present? 
    • Yes  : GO to A7.
    • No  : The concern was caused by a loose or corroded connector. CLEAR the DTCs. REPEAT self-test.
  7. A7 CHECK FOR CORRECT ABS MODULE OPERATION 
    • Disconnect the ABS module connector.
    • Check for:
      • corrosion
      • damaged pins
      • pushed-out pins
    • Connect the ABS module connector 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 ABS module. REFER to ANTI-LOCK BRAKE SYSTEM (ABS) 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.
