Solution

1. Preparation

Gather tools and parts required.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery, starting with the negative terminal to prevent electrical shorts.

2. Check and Replace Wheel Speed Sensors

Tools Required: Socket set, multimeter, torque wrench
Sub-steps:
1. Remove the wheel on which the ABS light is indicating an issue.
2. Locate the ABS wheel speed sensor (typically near the brake rotor).
3. Disconnect the sensor's electrical connector.
4. Use a multimeter to test the sensor's resistance; replace if out of specification.
5. If replacement is necessary, remove the old sensor by unscrewing it from its mount.
6. Install the new sensor, ensuring it is properly seated and secured.
7. Reconnect the electrical connector.

3. Inspect and Refill Brake Fluid

Tools Required: Brake fluid, funnel
Sub-steps:
1. Locate the brake fluid reservoir under the hood.
2. Remove the cap and check the fluid level; fill with the recommended brake fluid if low.
3. Inspect for any signs of contamination or debris in the fluid.
4. Replace the cap securely.

4. Reset ABS Light

Tools Required: OBD-II scanner
Sub-steps:
1. Reconnect the battery, starting with the positive terminal.
2. Start the vehicle and use the OBD-II scanner to clear any stored ABS fault codes.
3. Verify that the ABS light is off after clearing codes.
