Solution

1. Preparation

Gather tools and parts needed for the repair.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Clean Wheel Speed Sensors

Locate the wheel speed sensors at each wheel.
Remove the sensor harness connector.
Clean the sensor and mounting area with brake cleaner to remove dirt and debris.
Reconnect the harness and ensure a secure connection.

3. Check and Replace Brake Fluid

Locate the brake fluid reservoir.
Check the fluid level; if low, top off with DOT 3 or DOT 4 brake fluid as specified in the owner’s manual.
If the fluid is contaminated (dark or murky), perform a brake fluid flush.

4. Inspect Traction Control Module

Locate the traction control module, typically found near the ABS module.
Inspect the wiring harness for any signs of damage or corrosion.
If damaged, replace the wiring harness or the module as necessary.

5. Reconnect Battery and Clear Error Codes
