Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, basic hand tools
Ensure the vehicle is parked on a level surface, and the ignition is off.

2. Check Brake Fluid Level

Open the hood and locate the brake fluid reservoir.
Sub-steps:
- Remove the reservoir cap.
- Inspect the fluid level against the min/max markings on the reservoir.
- If low, add the recommended brake fluid type (e.g., DOT 4 or as specified in the owner's manual).

3. Inspect Wheel Speed Sensors

Tools Required: Socket set, multimeter
Raise the vehicle and secure it on jack stands.
Sub-steps:
- Remove the wheel to access the ABS sensor.
- Disconnect the sensor connector and inspect for dirt or corrosion.
- Use a multimeter to measure resistance across the sensor terminals; compare with specifications in the service manual.
- Clean or replace the sensor if necessary.

4. Check ABS Control Module

Tools Required: Basic hand tools, multimeter
Sub-steps:
- Locate the ABS control module according to the vehicle service manual.
- Inspect the wiring harness for frayed wires or loose connections.
- Test the module for power and ground using a multimeter; ensure correct voltage is reaching the module.

5. Clear Error Codes

Reconnect all components and use the OBD-II scanner to clear any stored ABS error codes.
Start the vehicle and check if the ABS light remains off.
