Powertrain Control Module (Pcm)
POWERTRAIN CONTROL MODULE (PCM)
| Refer to COMPONENT INDEX . |
The PCM commands the fuel pump PWM signal to be activated through a dedicated relay located in the Power Distribution Center (PDC) which sends a continuous 12 volt supply to the FPCM. The PCM also sends a PWM control signal directly to the FPCM. The PCM receives the pressure information from the fuel rail pressure sensor and sends a PWM signal on a dedicated signal circuit to the fuel pump control Module.
