Description
1 . The engine control module (ECM) controls the starting motor locking relay by
starting motor locking relay signal circuit. When the engine runs, the relay
prevents the starting motor from engaging.The relay loop is dependent on the
OEM wire. On some vehicles, it may connect back to the ECM, or on the other
vehicle, it connects to the chassis or cylinder. For loop details, refer to the
electrical wiring diagram of OEM.The starter motor locking relay circuit uses a
pulse width modulation (PWM) signal.The PWM signal is a pulse voltage signal
between the 0-VDC and the system voltage.The frequency of this pulse voltage
signal depends on the require of application type.
