Brake system diagnostics (ABS, wheel speed sensors)

Modern braking systems rely heavily on electronics. When warning lights such as ABS, traction control, or stability control appear on the dashboard, the issue is often related to electronic components such as wheel speed sensors or the ABS control module. During diagnostics we use a professional scan tool to read fault codes, analyze wheel speed sensor data in real time, and check the operation of the ABS system. However, a scan tool does not always show the full picture. In some cases the problem may be caused by damaged wiring, corroded connectors, or a faulty sensor, which requires additional testing with a multimeter and manual inspection to accurately locate the fault.
