Solution

1. Preparation

Gather tools and parts required for the repair.
Disconnect the negative battery terminal to ensure safety.

Tools Required:

OBD-II scanner
Socket set
Multimeter
Torque wrench

2. Inspect and Clean Wheel Speed Sensors

Locate the wheel speed sensors at each wheel hub.
Disconnect the electrical connector from each sensor.
Remove the sensor using a socket wrench.
Clean the sensor with a soft cloth and inspect for physical damage.
Reinstall the sensor and torque to manufacturer specifications.
Reconnect the electrical connector.

3. Check and Replace Traction Control Fuse

Locate the fuse box under the dashboard or engine compartment.
Identify the fuse related to the traction control system using the fuse diagram.
Remove the fuse and inspect it for continuity using a multimeter.
If the fuse is blown, replace it with a new one of the same amperage.

4. Inspect ABS Module

Using an OBD-II scanner, perform a diagnostic check on the ABS module.
Follow manufacturer instructions for testing the ABS pump and control module.
If the ABS module is faulty, replace it following these sub-steps:
- Disconnect the battery.
- Remove any wiring harnesses and brake lines connected to the ABS module.
- Unbolt the module from its bracket.
- Install the new ABS module and reconnect all components.
