LR3 Brake Wear Sensor Wiring
|
This 1 page wiring diagram pdf shows that both the front and rear brake pad wear sensors are part of a closed series circuit to ground.
In operation, when all is good, the series circuit is grounded and the amber brake wear warning indicator on the instrument panel is not illuminated.
When the pads on one wheel, either the left front, or right rear, become too worn, the respective sensor is "cut" which results in an open circuit condition. This causes the dash brake wear indicator to illuminate.
The circuit is like the old style Christmas light strings where one burned out bulb caused the whole string to go out.
A quick field fix to get the dash light to extinguish in lieu of replacing the sensor and pads etc is to disconnect the brake pad wear sensor and short across the two open conductors of the vehicle side connector plug. This of course means you now have a normal vehicle, one of the thousands that do not feature brake pad wear information systems.
