Troubleshooting truck -

Already have the ignition voltage reading that I cannot find.
Seen the battery voltage - not sure if it is the same - I do not think it is.

Also have the TCM on allison connected read PIDs in manual says to look at what the TCM is reporting fot the TFP E Solenoid Pressure switch.


Any way of adding more into the PID list - Is there a way even to go to the console and ready what these are in the TCM / ECM.
