Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle battery to prevent electrical shorts.
Ensure the vehicle is on a level surface and secure it using wheel chocks.

2. Inspect and Replace Wheel Speed Sensors

Tools Required: Socket set, torque wrench, multimeter.
Sub-steps:
1. Remove the wheel and tire to access the wheel speed sensor.
2. Unplug the electrical connector from the wheel speed sensor.
3. Use a multimeter to check the sensor's resistance; it should typically be around 1,000 ohms. Replace if outside specifications.
4. Remove the sensor bolt using the socket set.
5. Install the new sensor, torque the bolt to the manufacturer’s specifications (usually around 10-15 ft-lbs).
6. Reconnect the electrical connector and reinstall the wheel and tire.

3. Check and Adjust Brake Light Switch

Tools Required: Screwdriver.
Sub-steps:
1. Locate the brake light switch above the brake pedal.
2. Disconnect the switch connector.
3. Inspect for signs of damage or misalignment.
4. Adjust the switch if it’s out of position or replace it if damaged.
5. Reconnect the switch connector.

4. Inspect ABS Module

Tools Required: OBD-II scanner, socket set.
Sub-steps:
1. Use the OBD-II scanner to check for ABS-related codes.
2. If codes indicate a malfunction, using the socket set, remove the ABS module.
3. Check for loose connections or corrosion at the connector.
4. Replace the ABS module if necessary and re-install it.
5. Clear any error codes using the OBD-II scanner.
