Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal to ensure safety while working on the electrical system.

2. Retrieve Error Codes

Reconnect the battery terminal.
Use an OBD-II scanner to read ABS error codes.
Document the codes for reference to determine specific issues.

3. Inspect and Clean ABS Wheel Speed Sensors

Locate the ABS wheel speed sensors on each wheel hub.
Remove the sensor(s) by unscrewing any retaining bolts.
Clean the sensor tip and mounting area with brake cleaner to remove debris.
Reinstall the sensor and secure it with bolts.

4. Check ABS Module Connections

Locate the ABS control module typically mounted near the brake master cylinder.
Inspect the wiring harness and connectors for corrosion or damage.
Clean any corrosion with electrical contact cleaner and ensure the connections are secure.

5. Brake Fluid Check

Open the hood and locate the brake master cylinder.
Check the brake fluid level; if low, top off with the recommended brake fluid type (DOT 3 or DOT 4).
Inspect the fluid for contamination (dark color or debris) and replace if necessary.

6. Reset ABS Light

Reconnect the negative battery terminal.
Use the OBD-II scanner to clear the ABS error codes.
Turn the ignition on without starting the engine to check if the ABS light remains off.
