Trouble Shooting: Notes
The Digital Fuel Injection (DFI) system combines engine control, fuel metering and emission monitoring into a computer- controlled system. The Electronic Control Module (ECM) is the "brain" of the DFI system. The ECM is a digital electronic computer which receives and processes engine data, computes and interprets engine information, and sends instructions to various components. It provides fuel efficient operation with reduced exhaust emissions.
