Solution

1. Preparation

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

2. Inspect and Replace ABS Wheel Speed Sensors

Tools Required: Socket set, multimeter, torque wrench.
Remove the wheel to access the ABS sensor.
Disconnect the sensor's electrical connector.
Use a multimeter to test the sensor's resistance; compare with manufacturer specifications.
If faulty, remove the sensor by unscrewing it from the hub assembly.
Install the new ABS sensor and reconnect the electrical connector.
Reinstall the wheel and torque the lug nuts to manufacturer's specifications.

3. Check ABS Module and Wiring

Reconnect the negative battery terminal.
Inspect the ABS module for any signs of water intrusion or physical damage.
If the module is damaged, remove it according to the service manual instructions.
Replace it with a new or refurbished ABS module, ensuring all connections are secure.

4. Brake Fluid Check and Replacement

Check the brake fluid level; if low, top it off with the recommended fluid type (DOT 3 or DOT 4).
If the fluid appears contaminated, perform a brake fluid flush:
- Attach a brake bleeder kit to the brake calipers.
- Open the bleeder valve and allow old fluid to drain while adding new fluid to the reservoir.
- Repeat until clean fluid flows from all calipers.

5. Clear Error Codes

Reconnect the OBD-II scanner to the vehicle.
Clear any stored error codes related to the ABS system.
Conduct a test drive to ensure the ABS light does not reappear.
