Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect and Replace ABS Wheel Speed Sensors

Tools Required: Socket set, multimeter, cleaning brush.
Use a socket to remove the wheel and access the brake components.
Locate the ABS wheel speed sensor on each wheel hub.
Clean the sensor area with a brush to remove dirt.
Use a multimeter to test the sensor's resistance; replace if the readings are outside manufacturer specifications.
Reinstall the wheel and torque the lug nuts to the manufacturer's specifications.

3. Check and Replace ABS Fuses

Tools Required: Fuse puller or pliers.
Locate the fuse box (refer to the owner's manual for its location).
Identify the ABS fuse and pull it out using a fuse puller.
Inspect the fuse; if blown, replace it with a new fuse of the same amperage.
Reinstall the fuse box cover securely.

4. Brake Fluid Check and Replacement

Tools Required: Brake fluid, funnel, bleeder kit.
Check the brake fluid level in the master cylinder reservoir.
If low, top off with the recommended type of brake fluid (refer to the owner's manual).
If the fluid is dark or contaminated, perform a brake fluid flush using a bleeder kit to replace old fluid with new.

5. Reconnect Battery and Clear Codes

Reconnect the negative battery terminal.
Use the OBD-II scanner to clear any stored ABS error codes.
Test drive the vehicle to check if the ABS light remains off.
