Accelerometer (4WD)

The EBCM uses an accelerometer to sense vehicle motion. The EBCM provides 5 volts and ground to accelerometer. The accelerometer sends a voltage signal back to EBCM relative to vehicle motion. This signal is about 2.4-2.6 volts at zero speed change (constant motion), decreases when vehicle accelerates, and increases when vehicle decelerates. The accelerometer is located inside the parking brake lever bezel.
