Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the negative battery terminal to ensure safety while working on electrical components.
Allow the vehicle to cool down if it has been running.

2. Inspect Wheel Speed Sensors

Tools Required: Socket set, multimeter
Locate each wheel speed sensor, typically mounted near the wheel hub.
Clean the sensors with a mild cleaner to remove any debris.
Use a multimeter to check the resistance of each sensor (specifications may vary; refer to service manual).
Replace any faulty sensors with new ones.

3. Check Brake Fluid Level

Tools Required: None
Open the hood and locate the brake fluid reservoir.
Inspect the fluid level; if low, fill it to the recommended level with the appropriate brake fluid type (DOT 3 or DOT 4).
Check for any signs of leaks in the braking system.

4. Examine ABS Module and Wiring

Tools Required: Socket set, electrical cleaner
Locate the ABS module, usually found near the brake booster.
Inspect the wiring harness for any visible damage or corrosion.
Clean any corroded contacts with electrical cleaner.
Ensure all connections are secure.

5. Test Traction Control Module

Tools Required: Multimeter, service manual
Connect the multimeter to the TCM as specified in the service manual.
Verify that the TCM is receiving power and ground.
If the TCM is faulty, replace it with a new unit.
