Main controller (MC) digunakan untuk mengontrol operasi mesin. Signal kelistrikan dari engine control dial, dan bermacam sensor dan switch, dikirimkan ke MC. Setelah diterima di sirkuit logic-nya dan diproses, maka selanjutnya MC mengirim keluar signal pengontrol ke motor EC, solenoid valve unit, torque control solenoid unit, dan sirkuit pengontrolan yang lain untuk mengatur engine, pompa-pompa, motor, dan valve-valve.
