Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and the ignition is turned off.
Disconnect the battery to avoid any electrical shorts during inspection.

2. Inspect and Replace Wheel Speed Sensors

Tools Required: Socket set, multimeter
Remove the wheel on the affected axle to access the wheel speed sensors.
Disconnect the electrical connector from the wheel speed sensor.
Use a multimeter to test the sensor's resistance; compare with specifications in the service manual.
If the sensor is faulty, remove the mounting bolt and pull the sensor out of its housing.
Install the new wheel speed sensor, ensuring it fits snugly, and secure it with the bolt.
Reconnect the electrical connector and reinstall the wheel.

3. Check and Clean ABS Module Connections

Tools Required: Torque wrench, contact cleaner
Locate the ABS module, usually near the brake master cylinder.
Disconnect the wiring harness from the ABS module.
Inspect the connectors for corrosion; clean with contact cleaner if necessary.
Reconnect the harness and ensure it is tightly secured.
Torque any bolts to the manufacturer's specifications if applicable.

4. Tire Inspection and Replacement

Tools Required: Tire pressure gauge, tire iron
Check tire pressures with a tire pressure gauge and inflate to the recommended PSI.
Inspect all tires for uneven wear or low tread depth; replace any tires that do not meet safety standards.
