СИСТЕМА ECD - Цепь питания ECM


DESCRIPTION

When the ignition switch is turned on (IG), the battery voltage is applied to IGSW of the ECM. The output signal from the MREL terminal of the ECM causes a current to flow to the coil, closing the contacts of the engine room J/B (EFI relay) and supplying power to either terminal +B or +B2 of the ECM.
