Brake Pad Light Can't Go Off


Recommended Posts

Hi Guys,

Recently, my Brake Pad wear sensor light started flickering on.

I bought a complete set of rotors, pads, vibration dampers, and sensors for a complete brake service.

After I finished, the light is now constantly on. All sensor wires are hooked up at the connector side and sensors plugged into the new pads.

To troubleshoot, I would like to ask if the two pins on the sensor sockets will cause the light to go on if they are shorted, or not shorted?

I would like to test if any of the the new sensors are faulty from factory.

Thanks!

The light gos on if the sensor wiring is interrupted or made contact with ground (brake rotor).

Can I interpret that as the same as, if I unplugged all the connctors of the four sensors, the light theoretically should go off since the wires won't make a connection to ground? And further interpret that connecting them back one by one will reveal the faulty sensor when the light goes on when that particular sensor is connected?

No, the sensors are just wires once they break the connection is broken and the light goes on.

Either replace the sensors or jumper the connectors at the wheel so there is always a connection.

I see. Let me get this straight. The connectors are two-pin. The sensor is one continous wire connecting both pins. When the brake pad wears down, it breaks the wire at the pad, and the light appears. So, to test which of my new sensors are acting up, I jumper the two pins at the connector to find which corner of the car has a faulty sensor.

Have I summarized it correctly?

Thanks!
