Sorento V6-3.5L (2004)
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 ECU, 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 ECU through the MFI
control relay switch.
