Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and securely lifted if needed.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect and Clean ABS Wheel Speed Sensors

Locate each wheel speed sensor (usually mounted near the brake caliper).
Remove the sensor using a socket set.
Clean any debris or dirt from the sensor and its mounting area.
Reinstall the sensor and ensure it is securely fastened.

3. Check and Replace ABS Fuse

Open the fuse box and locate the ABS fuse (refer to the owner's manual for location).
Remove the fuse and inspect it visually for signs of damage.
Replace with an identical fuse if damaged, ensuring proper amperage.

4. Test ABS Module and Pump

Reconnect the battery terminal.
Use a multimeter to check the voltage and ground at the ABS module connector.
If the voltage readings are outside the specified range, replace the ABS module.
Check for proper operation of the ABS pump by activating it through the scanner.

5. Final Checks

Refill brake fluid if it was low and bleed the brakes to remove any air.
Recheck all connections and sensor positions to ensure everything is secure.
