Main Relay (Computer/Fuel System): Testing and Inspection

CONTROL RELAY

When the ignition switch is turned on, battery voltage is applied from the ignition switch to the PCM, turning ON the ignition power transistor and
energizing the MFI control relay coil. This turns ON the MFI control relay switch, and supplies power from the battery to the PCM through the MFI
control relay switch.
