Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the battery to prevent electrical shock.

2. Inspect Wheel Speed Sensors

Sub-steps:
1. Locate the wheel speed sensors at each wheel hub.
2. Clean any debris or dirt around the sensors and connectors.
3. Check the wiring harness for any signs of damage or wear.
4. Reconnect any loose connections and ensure they are secure.

3. Check ABS Control Module

Sub-steps:
