The anti-lock brake system (ABS) module receives wheel speed readings from each wheel speed sensor and processes this information to determine if an ABS event is necessary. The wheel speed sensor electrically senses each tooth of the wheel speed sensor indicators as it passes through the wheel speed sensor magnetic field.

The active wheel speed sensor generates a signal that is sent to the anti-lock brake system (ABS) module. The wheel speed sensor circuitry connects to the ABS module through 2 wires and a connector at each wheel speed sensor. When the ignition is turned to the RUN position, the ABS module carries out a self-test by sending a reference voltage to all of the wheel speed sensors through their circuitry to determine if they are functional.

The ABS module continuously monitors and compares the rotational speed of each wheel and when it detects an impending wheel lock, modulates brake pressure to the appropriate brake caliper. This is accomplished by triggering the hydraulic control unit (HCU) to open and close the appropriate solenoid valves. Once the affected wheel returns to normal speed, the ABS module returns the solenoid valves to their normal position, and normal (base) braking resumes.

The HCU has additional internal solenoid valves incorporated to enable control modulation of the wheel brake pressures.

The ABS module is self-monitoring. When the ignition switch is turned to the RUN position, the ABS module will do a preliminary electrical check, and at above 15 km/h (9 mph) the pump motor is turned on for approximately one-half second. Also, during all phases of operation the ABS module, with the vehicle in motion, checks for correct operation of the wheel speed sensors. Any malfunction of the ABS will cause the ABS to shut off. Normal power assisted braking, however, remains.

The traction control system controls wheelspin by modulating engine torque and applying, then releasing the rear brake to restore traction when driving on slippery or loose surfaces.

The traction control system can be disabled by pressing the traction control switch and is indicated by an indicator lamp in the traction control switch. The traction control will reset and return to normal traction assist when the ignition switch is cycled or when the traction control switch is pressed and released a second time.

ABS Module Configuration

The ABS module must be configured when a new ABS module is installed. For additional information, refer to MODULE CONFIGURATION .

Inspection and Verification

  1. Verify the customer concern.
  2. Verify the stoplamps operate correctly by pressing and releasing the brake pedal with the ignition switch in the ON position. If the stoplamps do not operate correctly, refer to «EXTERIOR LIGHTING»(/ford/five-hundred/i-2004-2007/remont/exterior-lights/#exterior-lighting-system) . If the stoplamps operate correctly, proceed to the next step.
  3. Visually inspect for obvious signs of mechanical or electrical damage.

The wheel speed sensor and sensor ring generates a square wave signal to the anti-lock brake system (ABS) module that is proportional to the wheel speed. The ABS module compares the wheel speed inputs from all the wheel speed sensors to determine an impending wheel lockup. Incorrect tire size can set these DTCs as well.

Engine torque modulation is achieved by regulating fuel and spark to the cylinders. The traction control system operates using the anti-lock brake system (ABS) module to interact with the powertrain control module (PCM) to reduce engine torque if the wheels loses traction and begins to spin during acceleration.

The instrument cluster sends a voltage reference signal to the traction control switch through circuit 1412 (WH/PK). When the traction control switch is pressed, the signal is grounded through circuit 1205 (BK). The instrument cluster then sends a traction control disable command over the controller area network (CAN).
