Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect and Replace Wheel Speed Sensors

Tools Required: Socket set, multimeter, torque wrench
Remove the wheel covering the affected hub (if applicable).
Disconnect the wiring harness from the wheel speed sensor.
Remove the sensor using a socket wrench (note torque specifications for reinstallation).
Test the sensor using a multimeter; if the reading is outside specified ranges, replace the sensor.
Install the new sensor and reconnect the wiring harness. Torque to manufacturer specifications.

3. Check and Top-Up Brake Fluid

Tools Required: Brake fluid (DOT 3 or 4 as specified), funnel
Locate the brake fluid reservoir under the hood.
Check the fluid level; if low, top up with the appropriate brake fluid.
Inspect for any signs of leaks around brake lines and calipers.

4. Test and Replace ABS Module (if necessary)

Tools Required: OBD-II scanner, socket set
Use the OBD-II scanner to check for ABS fault codes.
If faults are present, disconnect the ABS module and inspect for corrosion or damage.
Replace the ABS module if necessary, reconnecting all wiring securely and ensuring proper installation torque.

5. Inspect Traction Control Switch

Tools Required: Screwdriver set
Access the traction control switch located on the dashboard.
Inspect for physical damage or malfunction; replace if necessary.
