Fuel Shut-off Solenoid Relay: Description and Operation
CIRCUIT OPERATION
When the ignition switch is in the START or RUN position. it connects circuit A1 from fuse 3 in the Power Distribution Center (PDC) to circuit
A21. Circuit A21 feeds circuit F18 through fuse 9 in the fuse block. Circuit F18 powers the coil side of the high pressure fuel shut-off solenoid
relay The Powertrain Control Module (PCM) energizes the relay by providing the ground path for relay coil on circuit K31. Circuit K31 connects
to cavity C19 of the PCM.
Circuit A14 from fuse 8 in the PDC powers the contact side of the high pressure fuel shut-off solenoid relay When the relay energizes, it connects
circuits A14 and A61. Circuit A61 powers the high pressure fuel shut-off solenoid.
