Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect and Clean Wheel Speed Sensors

Locate the wheel speed sensors on each wheel hub.
Remove the sensor mounting bolts using a socket set.
Gently pull the sensor out of the hub and inspect for dirt or damage.
Clean the sensor and the mounting area with a brake cleaner.
Reinstall the sensor and torque the mounting bolts to manufacturer specifications (typically around 7-10 ft-lbs).

3. Check and Refill Brake Fluid

Locate the brake fluid reservoir under the hood.
Inspect the fluid level; if low, clean the reservoir cap before removing it.
Add the recommended brake fluid type (usually DOT 3 or DOT 4) until it reaches the full mark.
Reinstall the cap securely.

4. Inspect Wiring and Connectors

Visually inspect the wiring harness connected to the ABS module and wheel speed sensors.
Look for frayed wires or loose connectors; repair or replace as necessary.

5. Test the ABS Control Module

Reconnect the negative battery terminal.
Use the OBD-II scanner to check for active or stored fault codes in the ABS module.
If codes are present, follow the manufacturer's service manual for troubleshooting specific issues related to the ABS module.
