Solution

1. Preparation

Gather tools and parts before starting the repair. Ensure the vehicle is parked on a level surface and the ignition is off.
Tools Required: OBD-II scanner, multimeter, socket set, torque wrench, brake cleaner, and safety glasses.

2. Address Error Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Record any error codes related to the ABS system.
Clear the codes and check if they return after a test drive.

3. Inspect and Replace ABS Fuse

Locate the fuse box; refer to the owner's manual for the specific location of the ABS fuse.
Remove the ABS fuse and inspect it for continuity.
If the fuse is blown, replace it with a new fuse of the same amperage.

4. Check and Refill Brake Fluid

Open the brake fluid reservoir cap.
Check the fluid level; if low, add the recommended brake fluid (DOT 3 or DOT 4 as specified).
Inspect for any leaks in the brake lines or at the master cylinder.

5. Inspect Wheel Speed Sensors

Lift the vehicle using a jack and secure it with jack stands.
Remove the wheel to access the wheel speed sensors.
Inspect the wiring and connector for damage; clean any debris or dirt from the sensor.
Use a multimeter to check sensor resistance. The typical range should be between 1,000 to 2,000 ohms. Replace the sensor if values are outside this range.

6. Test ABS Module (if necessary)

If issues persist, check the ABS module for error codes and perform functionality tests.
If the module is faulty, replace it according to manufacturer's specifications.
