Natural Gas Vehicle Module
NOTE:
F150 and F350 Super Duty bi-fuel models use an Alternative Fuel Control Module (AFCM) to allow communication between PCM and AFCM. AFCM is incorporated within compuvalve on F150 and F350 Super Duty bi-fuel models.
Natural Gas Vehicle (NGV) module has 2 functions. The first function is to operate fuel injectors and is referred to as Injector Driver Module (IDM). IDM vehicle fuel indicator driver signals are based on Powertrain Control Module (PCM) fuel injector driver signals and are controlled directly by corresponding injector drivers in PCM. The greater demand of fuel injector current warrants an increased size of the injector driver and increased heat dissipation. Given these conditions, the PCM would not be suitable for location of these drivers. The IDM closely resembles PCM module in appearance. The second function is to control fuel gauge and is referred to as Fuel Indicator Module (FIM). See NATURAL GAS VEHICLE MODULE LOCATION table.
