Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to prevent any electrical shorts during troubleshooting.

2. Repair or Replace Faulty Components

ABS Sensors:
1. Locate the ABS sensor at each wheel hub.
2. Disconnect the wiring harness from the sensor.
3. Remove the mounting bolt(s) securing the sensor and gently pull it out.
4. Install the new sensor, ensuring it is seated properly.
5. Reconnect the wiring harness and secure with bolts.
ABS Module:
1. Disconnect the battery again if it was reconnected.
2. Locate the ABS module, typically near the master cylinder.
3. Disconnect the wiring harness from the module.
4. Remove the mounting bolts and detach the module.
5. Install the new module and reconnect the wiring harness securely.

3. Fluid Check and Replacement

Check the brake fluid level in the reservoir.
If low, top off with the manufacturer-recommended brake fluid (DOT 3 or DOT 4).
Bleed the brake lines if air is suspected in the system using the proper sequence.

4. Reconnect Battery

Reconnect the negative terminal of the battery.

5. Reset ABS Light

Use the OBD-II scanner to clear any stored ABS trouble codes and reset the ABS light.
