Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.

2. Scan for Error Codes

Use an OBD-II scanner to retrieve ABS-related error codes.
Note down any codes for reference when diagnosing further.

3. Inspect ABS Components

ABS Fuse and Relay:
- Locate the fuse box and check the ABS fuse.
- Replace the fuse if it is blown.
Wheel Speed Sensors:
- Raise the vehicle safely using jack stands.
- Inspect each wheel speed sensor; clean them with a cloth if dirty.
- If damaged, replace the sensors.

4. Check Wiring and Connectors

Visually inspect the wiring harness connected to the ABS module and wheel speed sensors.
Repair or replace any damaged wires or connectors as necessary.

5. Test ABS Module

Use a multimeter to check for voltage at the ABS module.
If there is no voltage, trace the wiring back to the fuse and relay.
If the module is faulty, replace it following manufacturer guidelines.

6. Reassemble and Test

Reconnect any components that were removed.
Lower the vehicle and ensure everything is secure.
Turn on the ignition to check if the ABS light is still illuminated.
