Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to prevent electrical shorts during repairs.

2. Inspect and Replace ABS Wheel Speed Sensors

Sub-steps:
1. Locate the wheel speed sensors at each wheel hub.
2. Remove the sensor wiring harness connector.
3. Unscrew the mounting bolt and carefully remove the sensor from the hub.
4. Inspect the sensor for damage and clean any debris from the mounting area.
5. Install the new ABS wheel speed sensor, ensuring it is properly seated.
6. Reconnect the wiring harness and secure it.

3. Check and Replace Brake Fluid

Sub-steps:
1. Remove the brake fluid reservoir cap.
2. Check the fluid level; if low, add the recommended brake fluid type (DOT 3 or DOT 4).
3. If fluid is contaminated, perform a brake fluid flush.
4. After refilling, replace the reservoir cap securely.

4. Reset ABS Light

Sub-steps:
1. Reconnect the battery terminals.
