Pinpoint Test D: C2005:77, C2006:77

WARNING: This page is about a different variant/trim than selected.
  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? 

  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
      C3529-1  OHM Ground
      C3529-2  OHM Ground
    • For the RH actuator motor, measure:
      Positive Lead Measurement/Action Negative Lead
      C3551-1  OHM Ground
      C3551-2  OHM 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  OHM C3529-2 
    • For the RH actuator motor, measure:
      Positive Lead Measurement/Action Negative Lead
      C3551-1  OHM 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  OHM C135-12 
      C3529-2  OHM C135-13 
    • For the RH actuator motor, measure:
      Positive Lead Measurement/Action Negative Lead
      C3551-1  OHM C135-3 
      C3551-2  OHM 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  VOLTAGE Ground
      C3529-2  VOLTAGE Ground
    • For the RH actuator motor, measure:
      Positive Lead Measurement/Action Negative Lead
      C3551-1  VOLTAGE Ground
      C3551-2  VOLTAGE 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.
    • Remove the parking brake actuator motor.

      REFER to: PARKING BRAKE ACTUATOR MOTOR .

    • 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?
