Solution

1. Preparation

Gather tools and parts required for the repair.
Disconnect the battery to prevent electrical shorts during repairs.
Ensure the vehicle is on a flat surface and securely lift it using jack stands if necessary.

2. Inspect and Repair Wheel Speed Sensors

Sub-steps:
1. Locate the wheel speed sensors at each wheel assembly.
2. Visually inspect the sensors and wiring for any signs of damage or corrosion.
3. Use a multimeter to check the resistance of each sensor. Replace any faulty sensors.
4. Clean any dirt or debris around the sensor area to ensure proper function.

3. Check Brake Fluid Level and Condition

Sub-steps:
1. Open the hood and locate the brake fluid reservoir.
2. Check the fluid level; top off with manufacturer-recommended brake fluid if low.
3. Inspect the fluid for contamination or discoloration and replace if necessary.

4. Inspect ABS Module

Sub-steps:
1. Locate the ABS module, typically near the master cylinder.
2. Check for any visible leaks or damage.
3. If DTCs indicate an ABS fault, consider replacing the module or having it serviced.

5. Test Traction Control Switch

Sub-steps:
1. Locate the traction control switch on the dashboard.
2. Use a multimeter to test the switch for continuity when pressed.
3. Replace the switch if it fails the continuity test.
