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.
- 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.
- P2 REVIEW THE DTCs FROM THE ABS MODULE SELF-TEST
- Review the DTCs retrieved and recorded during INSPECTION AND VERIFICATION .
- Is DTC C0022:13, C0022:14 or C0022:1D present?
- 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:ABS MODULE SPECIFICATIONS TABLE
ABS Module Circuit Brake Booster Solenoid C135-17 CCA22 (GY/YE) C1602-3 C135-31 VCA22 (GN/BN) C1602-4 - Are the resistances less than 5 ohms?
- 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.
- Measure the resistance between ground and:
- 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.
- 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.
- While observing the clevis on the brake booster push rod for movement, momentarily connect a fused jumper wire between ABS module C135-17, circuit CCA22 (GY/YE), harness side and the battery positive post.
- Does the brake pedal move?
- 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?
- Yes: GO to P8.
- No: INSTALL a new brake booster. REFER to REMOVAL AND INSTALLATION . CLEAR the DTCs. REPEAT the self-test.
- 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.
