Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the negative battery terminal to avoid electrical shorts.

2. Scan for Error Codes

Use an OBD-II scanner to retrieve any error codes related to the ABS system.
Document any codes present for further analysis.

3. Inspect Wheel Speed Sensors

Remove the wheel covers or tires, depending on access.
Locate each wheel speed sensor and clean any debris or dirt.
Check the sensor wiring for signs of wear or disconnection.
Reconnect any loose wiring and secure properly.

4. Check ABS Fuse

Locate the fuse box under the dashboard or in the engine compartment.
Identify the ABS fuse using the diagram on the fuse box cover.
Remove the fuse and check for continuity using a multimeter; replace if blown.

5. Examine Brake Fluid

Open the brake fluid reservoir cap.
Inspect fluid level; top off with the appropriate brake fluid type (DOT 3 or DOT 4).
If fluid is contaminated, perform a brake fluid flush.

6. Test ABS Control Module Wiring

Reconnect the battery and turn the ignition to the "ON" position without starting the vehicle.
Inspect wiring to the ABS module for loose or corroded connections.
If necessary, replace any damaged wiring.
