Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle battery to ensure safety while working on the electrical components.

2. Inspect and Replace Fuses

Locate the fuse box under the dashboard or in the engine compartment.
Remove the ABS-related fuses and inspect them for any signs of burning or breakage.
Replace any blown fuses with the same amperage rating.

3. Repair or Replace Wiring and Connectors

Visually inspect the wiring harness and connectors for any signs of wear or corrosion.
If damaged, repair the wiring with appropriate gauge wire and solder or replace connectors as necessary.

4. Test and Replace Wheel Speed Sensors (if necessary)

Disconnect the wheel speed sensors from the harness.
Using a multimeter, measure the resistance; it should typically be between 1,000 to 2,500 ohms.
Replace any faulty sensors with OEM parts, ensuring proper alignment during installation.

5. Replace the ABS Module (if necessary)

Remove the ABS module, typically located near the master cylinder.
Unbolt the module after disconnecting the wiring harness and brake lines (use a brake line wrench).
Install the new ABS module, ensuring to torque all bolts to manufacturer specifications (usually around 7-10 ft-lbs).
Reattach the brake lines and ensure there are no leaks.

6. Reconnect Battery and Clear Codes

Reconnect the vehicle battery.
Use the OBD-II scanner to clear any stored ABS trouble codes and ensure the system resets.
