PINPOINT TEST P: DTCs C0022:11, 12, 13, 14, 1D and 49

WARNING: This page is about a different car, the 2010 Mercury Milan, 2010 Lincoln MKZ, and 2010 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: Use the Flex Probe Kit for all test connections to prevent damage to the wiring terminals. Do not use standard multimeter probes.
  1. P1 VERIFY ALL WIRING CONNECTIONS 
    • Disconnect: ABS Module C135.
    • Disconnect: Brake Booster C1602.
    • Using a good light source, inspect each connector terminal for any corrosion.
    • Inspect both connectors for any pushed-out pins.

      Refer to the appropriate SYSTEM WIRING DIAGRAMS article for schematic and connector information.

    • Using a suitable mating terminal, check each female terminal for deformed or enlarged contacts by comparing the mating terminal's fit between each of the following pins:
      • C135-17
      • C135-31
      • C1602-3
      • C1602-4

    • Refer to the appropriate SYSTEM WIRING DIAGRAMS article for schematic and connector information.
    • Is each terminal free of corrosion, pushed-out pins or spread terminals? 
    • Yes:  GO to  P2.
    • No:  REPAIR the affected terminal(s). CLEAR the DTCs. REPEAT the self-test.
  2. P2 REVIEW THE DTCs FROM THE ABS MODULE SELF-TEST 
    • Yes:  GO to  P3.
    • No:  If DTC C0022:11 or C0022:49 were retrieved from the self-test, GO to  P4. If DTC C0022:12 was retrieved from the self-test, GO to  P5.
  3. P3 CHECK THE BRAKE BOOSTER SOLENOID CIRCUITS FOR AN OPEN 
    • Ignition OFF.
    • Measure the resistance between ABS module C135 harness side, and brake booster solenoid C1602 harness side as indicated in the following table below:

    • Are the resistances less than 5 ohms? 
    • Yes:  If DTC C0022:14 or C0022:1D was retrieved from the self-test, GO to  P4. If DTC C0022:13 was retrieved from the self-test, GO to  P6.
    • No:  REPAIR the affected circuit(s). CLEAR the DTCs. REPEAT the self-test.
  4. P4 CHECK THE BRAKE BOOSTER SOLENOID CIRCUITS FOR A SHORT TO GROUND 
    • Measure the resistance between ground and:
      • brake booster solenoid C1602-3, circuit CCA22 (GY/YE), harness side.
      • brake booster solenoid C1602-4, circuit VCA22 (GN/BN), harness side.

    • Are the resistances greater than 10,000 ohms? 
    • Yes:  GO to  P6.
    • No:  REPAIR the affected circuit(s). CLEAR the DTCs. REPEAT the self-test.
  5. P5 CHECK THE BRAKE BOOSTER SOLENOID CIRCUITS FOR A SHORT TO VOLTAGE 
    • Ignition ON.
    • Measure the voltage between ground and:
      • brake booster solenoid C1602-3, circuit CCA22 (GY/YE), harness side.
      • brake booster solenoid C1602-4, circuit VCA22 (GN/BN), harness side.

    • Is any voltage present? 
    • Yes:  REPAIR the affected circuit(s). CLEAR the DTCs. REPEAT the self-test.
    • No:  GO to  P6.
  6. P6 CHECK THE BRAKE BOOSTER SOLENOID FOR CORRECT OPERATION 
    • Ignition OFF.
    • Connect: Brake Booster C1602.
    • Connect: ABS Module C135.
    • Ignition ON.
    • Start then engine.
    • Apply and release the brake pedal.
    • Allow the engine to run for 10 to 15 seconds in order to build vacuum in the brake booster.
    • Ignition OFF.
    • Disconnect: ABS Module C135.
    • Connect a fused jumper wire between ABS module C135-31, circuit VCA22 (GN/BN), harness side and ground.

    • Does the brake pedal move? 
    • Yes:  GO to  P8.
    • No:  GO to  P7.
  7. P7 CHECK THE BRAKE BOOSTER SOLENOID 
    • Disconnect: All fused jumper wires.
    • Measure the resistance between ABS module C135-17, circuit CCA22 (GY/YE), harness side and ABS module C135-31, circuit VCA22 (GN/BN), harness side.

    • Is the resistance between 1 and 3 ohms? 
  8. P8 CHECK FOR CORRECT ABS MODULE OPERATION 
    • Disconnect: All Fused Jumper Wires (if not previously disconnected).
    • Check for:
      • corrosion
      • pushed-out pins
      • spread terminals
    • Connect: ABS Module C135.
    • Make sure the connector seats correctly, then operate the system and verify the concern is still present.
    • Is the concern still present? 
    • Yes:  INSTALL a new ABS module. REFER to Removal and Installation . 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. CLEAR the DTCs. REPEAT the self-test.
