Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, torque wrench
Ensure the vehicle is on a level surface and the ignition is turned off before beginning repairs.

2. Inspect Wheel Speed Sensors

Sub-steps:
1. Locate the wheel speed sensors at each wheel hub.
2. Disconnect the electrical connectors carefully.
3. Remove the sensors using the appropriate socket size.
4. Inspect the sensors for dirt, damage, or wear.
5. Clean the sensor area with a suitable cleaning agent if necessary.
6. Reinstall sensors and torque to manufacturer specifications.

3. Check ABS Module

Sub-steps:
1. Locate the ABS module, usually found near the brake master cylinder.
2. Inspect the ABS module connections for corrosion or loose wires.
3. Use a multimeter to check for proper voltage and ground at the ABS module.
4. If faulty, proceed to replace the ABS module according to manufacturer guidelines.

4. Brake System Inspection

Sub-steps:
1. Check the brake fluid level in the master cylinder reservoir.
2. If low, top off with the recommended brake fluid type (DOT 3 or DOT 4).
3. Inspect the brake pads and rotors for wear.
4. Replace any worn components and bleed the brake system if necessary.
