Diesel PCM Input

Injector Driver Module Feedback
The Injector Driver Module (IDM) provides an EF signal to the PCM which confirms that correct timing/duration of the PCM command was received by the IDM. The EF signal is also used to send diagnostic information about the IDM and fuel injector circuitry.
