Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the negative terminal of the battery to prevent electrical shock.

2. Scan for Error Codes

Connect the OBD-II scanner to the vehicle’s diagnostic port.
Turn on the ignition without starting the engine.
Read and note any ABS-related error codes.
Clear the codes and see if they return after a short test drive.

3. Inspect Wheel Speed Sensors

Locate each wheel speed sensor; they are typically mounted near the brake caliper.
Visually inspect the wiring and connector for any damage or corrosion.
Disconnect the sensor and use a multimeter to check for continuity.
If defective, replace the wheel speed sensor.

4. Check ABS Module and Connections

Locate the ABS control module, usually found near the brake master cylinder.
Inspect the module for any signs of moisture, corrosion, or physical damage.
Ensure all electrical connections to the module are secure and free from corrosion.

5. Brake Fluid Check

Remove the brake fluid reservoir cap and check the fluid level.
If the fluid is low, add the appropriate brake fluid (DOT 4 is commonly used).
If the fluid is contaminated (dark or dirty), perform a brake fluid flush.

6. Reassemble and Test

Reconnect the battery terminal.
Start the vehicle and check if the ABS light remains illuminated.
Test drive the vehicle to ensure proper ABS function and monitor for any warning lights.
