Solution

1. Preparation

Gather tools and parts needed for repair.
Disconnect the vehicle battery to ensure safety during the repair process.
Allow the vehicle to cool down if it has been running.

2. Inspect and Replace ABS Wheel Speed Sensors

Locate the Sensors:
- Identify the ABS wheel speed sensors at each wheel hub.
Remove the Sensor:
- Unplug the electrical connector.
- Remove any mounting bolts and extract the sensor from the hub.
Install New Sensor:
- Insert the new ABS wheel speed sensor into the hub.
- Secure it with mounting bolts and reconnect the electrical connector.

3. Check and Replace ABS Fuse

Locate the Fuse Box:
- Find the fuse box, typically located under the dashboard or in the engine compartment.
Inspect Fuse:
- Remove the ABS fuse and inspect it for continuity.
Replace Fuse:
- If blown, replace it with a new fuse of the same rating.

4. Brake Fluid Inspection

Check Fluid Level:
- Open the brake fluid reservoir cap and check the fluid level.
Top Off Fluid:
- If low, add the appropriate brake fluid as specified in the owner’s manual.
Check for Leaks:
- Inspect brake lines and connections for any signs of leakage.

5. Reconnect Battery and Clear Codes

Reconnect Battery:
- Reattach the battery cables securely.
Clear Fault Codes:
- Use the OBD-II scanner to clear any stored ABS fault codes.
