Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and securely supported with jack stands.

2. Inspect Wheel Speed Sensors

Tools required: Socket set, multimeter
Disconnect the battery to prevent electrical shorts.
Remove the wheel and tire to access the wheel speed sensor.
Disconnect the sensor connector and inspect for corrosion or damage.
Use a multimeter to check the sensor's resistance; compare with manufacturer specifications.
If faulty, replace the wheel speed sensor.

3. Check ABS Module

Tools required: OBD-II scanner
Reconnect the battery.
Use the OBD-II scanner to check for any fault codes related to the ABS module.
If codes indicate a malfunction, inspect the wiring harness and connectors for damage.
If necessary, replace the ABS module according to workshop manual specifications.

4. Brake Fluid Check

Tools required: Brake fluid tester or gauge
Open the hood and locate the brake fluid reservoir.
Check the fluid level; if low, add the appropriate brake fluid type (refer to owner’s manual).
Inspect for leaks in brake lines or connections.

5. Test Traction Control Switch

Tools required: Multimeter
Locate the traction control switch in the vehicle.
Disconnect the switch connector and test for continuity using a multimeter.
If the switch fails the continuity test, replace it.
