Circuit Description

Battery voltage is supplied to circuit +BM at ECM harness connector E9 at all times. If DTC P1127 is present, ECM turns off power to throttle motor and magnetic clutch, and throttle valve is fully closed by return spring. When this occurs, opening angle of throttle valve is controlled by accelerator pedal by means of a throttle cable. DTC is set when ECM detects an open ETCS power source circuit. Possible causes are:

• ETCS power source circuit is open.
• Defective ECM.
