Why Won’t My Brake Pad Warning Light Reset?
Sometimes, even after replacing the brake pads and attempting the reset procedures, the warning light persists. This could be due to several factors:
-
Faulty Sensor: The brake pad wear sensor itself might be malfunctioning and needs replacement.
-
Wiring Issues: Damaged or corroded wiring connected to the sensor can prevent the signal from reaching the car’s computer.
-
Control Module Problems: In rare cases, a problem with the ABS control module can cause the warning light to stay on.
“Always check the wiring and sensor connections thoroughly,” recommends Jane Doe, Lead Diagnostic Specialist at Doe Automotive Diagnostics. “A simple loose connection can sometimes be the culprit behind a persistent warning light.”
