Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the negative battery terminal to prevent electrical shocks.

2. Inspect Wheel Speed Sensors

Locate the wheel speed sensors at each wheel hub.
Remove the wheel covers and wheel, if necessary, to access the sensors.
Clean any dirt or debris from around the sensors.
Check the wiring for frays or disconnections and repair or replace as needed.

3. Check Brake Fluid Level

Locate the brake fluid reservoir under the hood.
Inspect the fluid level; add brake fluid if low, ensuring it meets manufacturer specifications.
Check for any leaks in the brake lines or around the reservoir.

4. Examine DSC Module

Locate the DSC control module, usually found near the ABS unit.
Inspect for signs of moisture, corrosion, or physical damage.
Reconnect any loose connectors and ensure all connections are secure.

5. Test ABS Sensors

Use a multimeter to test the resistance of each ABS sensor.
Refer to the vehicle's service manual for the specific resistance values.
Replace any sensors that fall outside the specified range.

6. Clear Error Codes

Reconnect the negative battery terminal.
Use the diagnostic scanner to clear any error codes from the system.
Perform a test drive to see if the DSC light re-illuminates.
