PINPOINT TEST C: DTCs C1095 AND C1096

WARNING: This page is about a different car, the 2012 Ford Pickup, 2012 Ford F550 Super Duty, 2012 Ford F450 Super Duty, and 2012 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.
NOTE: Failure to disconnect the battery when instructed results in false resistance readings. Refer to BATTERY, MOUNTING AND CABLES .
  1. C1 CHECK FOR ABS MODULE ON-DEMAND DTCs 
    • Ignition ON.
    • Using the scan tool, clear all ABS module DTCs.
    • Ignition OFF.
    • Ignition ON.
    • Enter the following diagnostic mode on the scan tool: Self Test - ABS Module.
    • Retrieve and record all ABS module DTCs.
    • Is DTC C1095 or C1096 present? 
      1. Yes  : GO to C2.
      2. No  : For all other DTCs, REFER to the ABS Module DTC Chart - Three-Channel .

        If no other DTCs are set, the system is operating correctly at this time.

  2. C2 CHECK THE ABS PUMP MOTOR 
    • Listen for the ABS pump motor.
    • Is the ABS pump motor running continuously? 
      1. Yes  : INSTALL a new ABS module. REFER to Anti-Lock Brake System (ABS) Module . TEST the system for normal operation.
      2. No  : GO to C3.
  3. C3 CHECK THE ABS PUMP MOTOR CONTROL OUTPUT COMMAND (ABS_MTR) 
    • Enter the following diagnostic mode on the scan tool: DataLogger - ABS Module.
    • Toggle the ABS_MTR output command ON.
    • Does the HCU pump motor run for approximately 2 seconds? 
      1. Yes  : TOGGLE the ABS_MTR output command OFF. GO to C4.
      2. No  : TOGGLE the ABS_MTR output command OFF. GO to  C5.
  4. C4 CHECK FOR RETURNING ABS MODULE DTCs 
    • Using the scan tool, clear all ABS module DTCs.
    • Cycle the ignition switch and test drive the vehicle above 32 km/h (20 mph).
    • Enter the following diagnostic mode on the scan tool: Self Test - ABS Module.
    • Are any DTCs present? 
      1. Yes  : If DTC C1096 is present, GO to  C7.

        If DTC C1095 is present, INSTALL a new HCU. REFER to Hydraulic Control Unit (HCU) . CLEAR the DTCs. REPEAT the self-test.

        If the concern is still present, GO to  C8.

        For all other ABS module DTCs, REFER to the ABS Module DTC Chart - Three-Channel .

      2. No  : The system is operating correctly at this time.
  5. C5 CHECK THE VOLTAGE TO THE ABS MODULE FOR PUMP MOTOR ACTIVATION 
    • Ignition OFF.
    • Disconnect: ABS Module C135.
    • Measure the voltage between ABS module C135-1, circuit SBB96 (VT/RD), harness side and ground.

    • Is the voltage greater than 10 volts? 
      1. Yes  : GO to C6.
      2. No  : VERIFY BJB fuse 96 (50A) is OK. If OK, REPAIR circuit SBB96 (VT/RD). 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.
  6. C6 CHECK GROUND CIRCUITS FOR CONTINUITY 
    • Ignition OFF.
    • Disconnect: Battery Negative Cable.
    • Measure the resistance between the ABS module C135-13, circuit GD163 (BK/GY), harness side and ground; and between the ABS module C135-38, circuit GD163 (BK/GY), harness side and ground.

    • Are the resistances less than 5 ohms? 
      1. Yes  : GO to C7.
      2. No  : REPAIR circuit GD163 (BK/GY). CLEAR the DTCs. REPEAT the self-test.
  7. C7 CHECK THE ABS MODULE GROUND EYELET AT THE CHASSIS 
    • Remove the bolt retaining G135 on the LT frame rail.
      • 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: Self Test - ABS Module.
    • Is DTC C1095 or C1096 retrieved? 
      1. Yes  : INSTALL a new HCU. REFER to Hydraulic Control Unit (HCU) . CLEAR the DTCs. TEST the system for normal operation.

        If the concern is still present, GO to C8.

      2. No  : The concern was caused by a loose or corroded connector. CLEAR the DTCs. REPEAT self-test.
  8. C8 CHECK FOR CORRECT ABS MODULE OPERATION 
    • Disconnect the ABS module connector.
    • Check for:
      • corrosion
      • damaged pins
      • pushed-out pins
