Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety while working on electrical components.
Ensure the vehicle is on a level surface and securely lifted if necessary.

2. Inspect ABS Wheel Speed Sensors

Tools Required: Socket set, multimeter
Remove the wheel on which the ABS sensor is being inspected.
Locate the ABS wheel speed sensor and disconnect the electrical connector.
Use a multimeter to measure the sensor's resistance; refer to the service manual for the specified range.
If the reading is outside the specified range, replace the sensor.

3. Check ABS Module and Wiring

Visually inspect the ABS module and wiring harness for any damage or corrosion.
If corrosion is present, clean the connectors with electrical contact cleaner and reconnect.
If the wiring is damaged, repair or replace the affected wiring.

4. Brake Fluid Inspection

Check the brake fluid reservoir for proper fluid level.
If the fluid is low, top it off with the recommended brake fluid type.
If the fluid appears contaminated, flush the brake system and replace with new fluid.

5. Conduct Road Test

Reconnect the battery.
Start the vehicle and check if the ABS light turns off after a few seconds.
Conduct a road test to ensure ABS functionality and monitor for any recurrence of the warning light.
