Circuit/System Description
The FPCM Relay communicates with the FPCM via CAN serial data. The FPCM Relay diagnostics are reported out via the FPCM. The FPCM Relay controls the brush-less, 3-phase fuel pump by providing variable, continuous PWM speed control. The nominal current supplied to the fuel pump is 15 amps, with a maximum limit of 25 Amps.
