Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety during repairs.
Gather diagnostic scanner for code reading.

2. Retrieve Error Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Turn the ignition to the "On" position without starting the engine.
Read and record any stored error codes related to traction control or ABS.

3. Inspect Wheel Speed Sensors

Raise the vehicle using a jack and secure it with jack stands.
Remove the wheel to access the wheel speed sensor.
Visually inspect the sensor for damage or loose connections.
Clean the sensor and its connector if dirt or debris is present.

4. Check Brake Fluid and System

Inspect the brake fluid reservoir for proper fluid level.
If low, fill with the manufacturer-recommended brake fluid.
Inspect brake lines for leaks or damage.

5. Test ABS Module

Using the OBD-II scanner, check for ABS-related fault codes.
If codes are present, follow the manufacturer's diagnostic procedure for the ABS module.
Repair or replace the ABS module if necessary.

6. Inspect Throttle Position Sensor

Locate the throttle position sensor on the throttle body.
Use a multimeter to test the sensor according to the manufacturer’s specifications.
Replace the sensor if it fails to meet specifications.
