Injector Driver Module: Description and Operation
Diesel PCM Output
Injector Driver Module
The Injector Driver Module controls power to the fuel injectors based on information received from the PCM. The Injector Driver Module receives
two digital control signals from the PCM: the Fuel Delivery Control Signal and the Camshaft Position signal. The Fuel Delivery Control Signal is used
by the Injector Driver Module to control injection timing and injection duration. The CMP signal provides synchronization to the engine's first and the
fifth injector (firing order, cylinders number one and four). The Injector Driver Module verifies that Fuel Delivery Control Signal and CMP occur at
valid timing intervals for synchronization.
