Anti-Lock Brake System - 4-Wheel: Operation: Accelerometer

The EBCM uses an accelerometer to sense vehicle motion. EBCM provide a 5-volt reference and ground to the accelerometer. Accelerometer sends a voltage signal back to the EBCM relative to vehicle motion. Voltage should be about 2.4-2.6 volts at zero speed change (constant motion). Voltage decreases during acceleration and increases during deceleration.
