In the Cummins Electronic Fuel injection book it states that. On page 99 I read this very carfully and memerized it . When the FPCM detects these circuits changing state, fuel delivery is changed and certain diagnostics are allowed to run at idle.

What are the the diagnostics that are going on?
Can anyone get me the info ( e-mail me or and will remain confidential )

Or talk to the training centers and ask for the info ( If someone can do this I will pay you for your time when I can. )( have been getting the big ZERO up here and are NO HELP AT ALL .
The diagnostics say that .

Idle Validation Sensor-Accelerator Pedel Sensor error- Idle Validation sensor indicates Idle On at the same time APPs signal indicates engine under acceleration.
The under acceleration must be comming from the speed sensor and maybe acomparitor cct is used. If there is avery high resistance in the off-idle validation cct >100k ohms AT 2.64 million ohms will the ECM see a signal and will it still work??????? And set a code and if a code what code should be their and if not a code why not and how to check it out????

Is anyone able to find out the info please??
