The IDM creates a constant 48 volt (DC) supply to all injectors by making and breaking a 12 volt source across a coil in the…
The IDM distributes current to the injectors. The IDM controls fueling to the engine by sending high voltage pulses to the OPEN and CLOSE coils…
The IDM has three functions: • Electronic distributor for injectors • Power source for injectors • IDM and injector diagnostics
The IAH system warms the incoming air supply prior to cranking to aid cold engine starting and reduce white smoke during warm-up. The ECM is…
The IPR valve controls pressure in the Injection Control Pressure (ICP) system. The IPR valve is a variable position valve controlled by the ECM. This…
The brake shut-off valve controls pressure in the oil gallery of the high-pressure oil rail. When the engine brake is activated, the ECM provides power…
The EGR valve controls the flow of exhaust gases into the inlet and EGR mixer duct. The EGR drive module controls the EGR actuator. The…
The VGT control module controls vane position in the turbine housing. Vane position is controlled by a switching voltage source in the ECM. The ground…
The ECM controls engine operation with the following: • Variable Geometry Turbocharger (VGT) control module • EGR drive module and control valve • Diamond Logic®…
