Solution

1. Preparation

Gather required tools and parts.
Ensure the vehicle is parked on a level surface with the engine off.
Disconnect the negative battery terminal to avoid electrical issues.

2. Inspect and Replace ABS Wheel Speed Sensors

Tools Required: Socket set, torque wrench, multimeter
Remove the wheel corresponding to the ABS sensor being inspected.
Unclip the ABS sensor cable from any clips along the suspension.
Disconnect the ABS sensor connector.
Use a multimeter to test the sensor's resistance; if it’s outside manufacturer specifications, replace the sensor.
Install the new sensor by reversing the removal steps and torque to manufacturer specifications.

3. Check and Refill Brake Fluid

Tools Required: Brake fluid (DOT 3 or DOT 4 as specified by manufacturer), funnel
Inspect the brake fluid reservoir; if the fluid is low, refill it to the proper level using the recommended brake fluid type.
Check for leaks in the brake lines and around the master cylinder.

4. Repair or Replace ABS Module (if needed)

Tools Required: Socket set, torque wrench
Remove any components obstructing access to the ABS module.
Disconnect the electrical connectors from the ABS module.
Unbolt the ABS module and replace it with a new or refurbished unit, ensuring all bolts are torqued to specifications.
Reconnect the electrical connectors and any other components removed during the process.
