Engine Restart Bypass Relay Control
EMCM controls the Engine Restart Bypass Control Relay and activates the Engine Restart Bypass Relay. When the restart conditions are satisfied, EMCM turns ON the Engine Restart Bypass Control Relay instantaneously right after the restart and opens the Engine Restart Bypass Relay for a moment. This allows a current to pass the inner resistance circuit right after the starter motor is activated. When the starter motor is rotating, the voltage is directly supplied to the starter motor without being passed through the inner resistance circuit in the Engine Restart Bypass Relay because the Engine Restart Bypass Relay is closed. In this way, EMCM enables the battery voltage stabilization and reduces the battery deterioration rate by decreasing the battery voltage drop resulted from cranking at an engine restart.
