At auto idle stop
The powertrain control module (PCM) determines whether activating the auto idle stop or not by signals from each unit, sensor, and switch. When the PCM determines that the conditions are met for the auto idle stop system, the PCM stops the engine by cutting the fuel injection, and also enables the starting assist brake function to operate. while the auto idle stop is operating, the auto idle stop indicator (green) on the gauge control module lights, and the low oil pressure indicator and the charging system indicator go off.
