Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal to prevent electrical shock.

2. Inspect Wheel Speed Sensors

Sub-steps:
1. Locate the wheel speed sensors (typically near the brake calipers on each wheel).
2. Remove any debris or dirt from the sensor area using a clean cloth.
3. Check wiring harnesses for damage or disconnection.
4. Use a multimeter to test the resistance of each sensor (should typically be between 1000-2000 ohms; refer to service manual for exact specs).
5. Replace any faulty sensors.

3. Check ABS Module and Connections

Sub-steps:
1. Remove the plastic cover to access the ABS module.
2. Inspect the electrical connectors for corrosion or damage.
3. Clean the connectors with electrical contact cleaner.
4. Reconnect the connectors securely.
5. If the module is faulty, replace it according to manufacturer specifications.

4. Verify Brake Fluid Level

Sub-steps:
1. Check the brake fluid reservoir located near the driver's side of the engine bay.
2. If the fluid is low, top it off with the recommended brake fluid type (typically DOT 3 or DOT 4).
3. Inspect for any visible leaks in the brake lines or around the master cylinder.

5. Test Traction Control Switch

Sub-steps:
1. Locate the traction control switch, usually found on the dashboard or center console.
2. Test the switch for proper function; if stuck, clean or replace it.
3. Ensure the switch is properly reconnected.
