СИСТЕМА ECD - Выходная цепь VC


DESCRIPTION

The ECM constantly generates 5 V power from the battery voltages supplied to the +B (BATT) terminal to operate the microprocessor. The ECM also provides this power to the sensors through the VC output circuit.

COROLLA, AURIS. ZZE150 ZRE151,152 NDE150.Система Управления Двигателем 1Ad-Ftv.Система Ecd.Система Ecd Выходная Цепь Vc

When the VC circuit is shorted, the microprocessor in the ECM and sensors that are supplied with power through the VC circuit are deactivated because the power is not supplied from the VC circuit. Under this condition, the system does not start up and the MIL does not illuminate even if the system malfunctions.
УКАЗАНИЕ:
Under normal conditions, the MIL is illuminated for several seconds when the ignition switch is first turned on (IG). The MIL goes off when the engine is started.
