PCM Solenoid Fuse

[FrankJ]

A quick look for "solenoid fuse fault" in the PCM manual didn't find a description of exactly what that means. I suspect that it is something internal to the PCM rather than the supply fuse. Perhaps the 12 volt solenoids are overdrawing the 24 V supply and disabling the solenoid outputs. If the fault was referring the PCM supply fuse, i think it would be worded differently.

I like connecting the PCM to a 20 amp breaker slot rather than the fused output. I read table 4.2 of rule R48 as allowing that.

Frank,
I don't think that is what R48 is saying. It is referring to only one load is allowed on the outputs designated for the PCM and VRM. It further speaks to the branch circuits in general. R44 actually points to using the PCM output marked on the PDP.

R44 allows a PCM to be connected to the same fuse as the VRM, but does not require it. R48 allows a PCM to be connected to a circuit breaker.
