PINPOINT TEST C: DTCs C1095 AND C1096

WARNING: This page is about a different car, the 2013 Ford F-550 Super Duty, 2013 Ford F-450 Super Duty, 2013 Ford F-350 Super Duty, and 2013 Ford F-250 Super Duty. 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.

    • 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
    • Connect the ABS module connector and make sure that it seats correctly.
