Yale ERC040AHN36TE082:
code 4 and PPP on Display

SN: C814N02800G
We have been having a problem with code 4, replaced switch and problem went away.
truck runs great for long periods of time then code 4 again, parking brake switch is good, 100% contact at switch and switch connections, but still having code4, went out today to check wiring and troubleshoot the code 4 and now have a PPP on display.
I have schematic's and wiring Diagrams.
What does PPP mean on display?
is there a way to read stored codes, inputs and outputs with display?
Grateful for any input
Thanks, James

Well the PPP on display went away, thinking that was due to very high humidity.
still have the code 4,
the schematic I have is for 42 pin connector at controller.
The truck has Danaher controller with 32 pin connector.
pull some more hair out and keep looking forward.

Went back today and everything working as normal.
one bare wire and corrosion somewhere..
