why does my Ford Explorer ABS light come on and traction control disabled?

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a level surface and the ignition is turned off.
• Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect and Clean Wheel Speed Sensors

• Sub-steps:
  1. Raise the vehicle using a jack and secure it with jack stands.
  2. Remove the wheel on the affected corner.
  3. Locate the ABS wheel speed sensor; it is usually mounted near the axle or brake caliper.
  4. Disconnect the electrical connector from the sensor.
  5. Remove the sensor using a socket or wrench (note torque specifications for reinstallation).
  6. Clean the sensor and the mounting hole with brake cleaner to remove debris.
  7. Reinstall the sensor, ensuring it is properly secured and reattach the electrical connector.

3. Repair or Replace Faulty Components

• Sub-steps:
  1. If error codes indicate a specific sensor failure, replace the faulty ABS wheel speed sensor with a new one.
  2. If the ABS module is faulty, remove it by disconnecting the wiring harness and unscrewing the mounting bolts.
  3. Install the new ABS module and reconnect the wiring harness.
  4. Reconnect the negative battery terminal and ensure all connections are secure.

4. System Reset

• Sub-steps:
  1. Use the OBD-II scanner to clear any stored error codes from the ABS and traction control systems.
  2. Perform a system reset if required by the vehicle’s manufacturer.
