Pinpoint Test D : C2005:77, C2006:77

WARNING: This page is about a different car, the 2016 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.

  1. D1 CHECK FOR OTHER ABS (ANTI-LOCK BRAKE SYSTEM) MODULE DIAGNOSTIC TROUBLE CODES (DTCS)

    • Ignition ON.
    • Using a diagnostic scan tool, carry out the ABS module self-test.

    Is DTC C2005:74 or C2006:74 present? 

    Yes  DIAGNOSE DTC C2005:74 or C2006:74 before diagnosing DTC C2005:77 or C2006:77. GO to Pinpoint Test C 
    No  If DTC C2005:77 or C2006:77 is present, GO to  D2
    For all other ABS module Diagnostic Trouble Codes (DTCs), GO to the DTC Chart: Anti-Lock Brake System (ABS) Module .

  2. D2 CHECK THE ACTUATOR MOTOR CIRCUITS FOR A SHORT TO GROUND

    • Ignition OFF.
    • Disconnect ABS module C135 .
    • Disconnect the suspect parking brake actuator motor electrical connector.
    • For the LH actuator motor, measure:
      Positive Lead Measurement / Action Negative Lead

      		 Ground

    Are the resistances greater than 10, 000 ohms? 

    Yes  GO to  D3
    No  INSPECT the actuator motor jumper harness and connectors for correct routing, damaged connectors, spread terminals, bent or pushed-out pins or any signs of corrosion. INSTALL a new jumper harness as necessary.If the jumper harness is OK, REPAIR the circuit.

  3. D3 CHECK THE ACTUATOR MOTOR CIRCUITS FOR A SHORT TOGETHER

    • For the LH actuator motor, measure:
      Positive Lead Measurement / Action Negative Lead
      C3529-1
      GFD70560Courtesy of FORD MOTOR COMPANY
      		 C3529-2
    • For the RH actuator motor, measure:
      Positive Lead Measurement / Action Negative Lead
      C3551-1
      GFD70560Courtesy of FORD MOTOR COMPANY
      		 C3551-2

    Is the resistance greater than 10, 000 ohms? 

    Yes  GO to  D4
    No  INSPECT the actuator motor jumper harness and connectors for correct routing, damaged connectors, spread terminals, bent or pushed-out pins or any signs of corrosion. INSTALL a new jumper harness as necessary.If the jumper harness is OK, REPAIR the circuit.

  4. D4 CHECK THE ACTUATOR MOTOR CIRCUITS FOR AN OPEN

    • For the LH actuator motor, measure:
      Positive Lead Measurement / Action Negative Lead
      C3529-1
      GFD70560Courtesy of FORD MOTOR COMPANY
      		 C135-12
      C3529-2
      GFD70560Courtesy of FORD MOTOR COMPANY
      		 C135-13
    • For the RH actuator motor, measure:
      Positive Lead Measurement / Action Negative Lead
      C3551-1
      GFD70560Courtesy of FORD MOTOR COMPANY
      		 C135-3
      C3551-2
      GFD70560Courtesy of FORD MOTOR COMPANY
      		 C135-2

    Are the resistances less than 3 ohms? 

    Yes  GO to  D5
    No  INSPECT the actuator motor jumper harness and connectors for correct routing, damaged connectors, spread terminals, bent or pushed-out pins or any signs of corrosion. INSTALL a new jumper harness as necessary.If the jumper harness is OK, REPAIR the circuit.

  5. D5 CHECK THE ACTUATOR MOTOR CIRCUITS FOR A SHORT TO VOLTAGE

    NOTE: Performing this step sets Diagnostic Trouble Codes (DTCs) in the ABS module.

    • Ignition ON.
    • For the LH actuator motor, measure:
      Positive Lead Measurement / Action Negative Lead
      C3529-1
      GFD70561Courtesy of FORD MOTOR COMPANY
      		 Ground
      C3529-2
      GFD70561Courtesy of FORD MOTOR COMPANY
      		 Ground
    • For the RH actuator motor, measure:
      Positive Lead Measurement / Action Negative Lead
      C3551-1
      GFD70561Courtesy of FORD MOTOR COMPANY
      		 Ground
      C3551-2
      GFD70561Courtesy of FORD MOTOR COMPANY
      		 Ground

    Is any voltage present? 

    Yes  GO to  D6
    No  INSPECT the actuator motor jumper harness and connectors for correct routing, damaged connectors, spread terminals, bent or pushed-out pins or any signs of corrosion. INSTALL a new jumper harness as necessary.If the jumper harness is OK, REPAIR the circuit.

  6. D6 INSPECT THE ACTUATOR MOTOR FOR EVIDENCE OF BRAKE FLUID OR WATER LEAKS

    • Ignition OFF.
    • Inspect the actuator motor and brake caliper for evidence of brake fluid leaks or water egress.

    Is there any evidence of brake fluid leaks or water egress? 

    Yes  If evidence of water egress is found, IDENTIFY and REPAIR the root cause.If evidence of a break fluid leak is found, INSTALL a new brake caliper and parking brake actuator motor assembly. Refer to: Brake Caliper .
    No  GO to  D7

  7. D7 INSPECT THE BRAKE CALIPER FOR BRAKE FLUID LEAKS

    • Clean any dirt or residue from the brake caliper.
    • Apply and release the brake pedal.
    • Inspect the brake caliper for signs of brake fluid leaks.

    Are there any signs of brake fluid leaks? 

    Yes  INSTALL a new rear brake caliper and parking brake actuator motor. Refer to: Brake Caliper .
    No  INSTALL a new parking brake actuator motor. Refer to: Parking Brake Actuator Motor .
