Circuit Description

Battery voltage is supplied to G sensor from switched ignition to "E37-1". EBCM is connected to G sensor by a ground circuit and a signal circuit.

G sensor converts forward and rearward motion into a voltage signal used by EBCM for an additional speed reference. With vehicle in "Park", or at steady speed, the voltage signal will range from 2, 4 to 2.6 V.

During forward acceleration voltage will increase, during deceleration voltage will decrease.
