Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to prevent electrical shorts.

2. Scan for Codes

Use an OBD-II scanner to read the ABS trouble codes.
Document any codes for reference during repairs.

3. Inspect and Replace Fuse

Locate the ABS fuse in the fuse box (refer to the owner’s manual for specific location).
Use a multimeter to check for continuity.
If blown, replace it with a new fuse of the same amperage.

4. Check Wheel Speed Sensors

Raise the vehicle and remove the wheel for access to the wheel speed sensors.
Inspect the sensors for physical damage or dirt accumulation.
Clean sensors with brake cleaner if necessary.
If damaged, replace with new sensors.

5. Inspect Brake Fluid Level

Open the hood and locate the brake fluid reservoir.
Check the fluid level; if low, top off with the manufacturer-recommended brake fluid (DOT 3 or DOT 4).
Inspect for leaks in brake lines or at the master cylinder.

6. Test ABS Module and Pump

Reconnect the battery and use the OBD-II scanner to clear any existing codes.
Start the vehicle and perform a brake test to see if the ABS light reappears.
If the light returns, further testing of the ABS module may be necessary, which may require professional diagnostic equipment.
