Jake switch settings in Esa

[Btech]

I was just looking at the wiring for both ECM's and OEM side datalink wiring is identical pinout between the 2, there is a 250k line and a 500k line on both so what ever the 2016 truck used before is what it would still be using so long as the ECM to cab harness wasn't changed. so that should be fine.

Does the tach, and other engine gauges on the dash work? If they do then communication between CECU and ECM is working.

Are there any messages/errors in insite under advanced ECM data / J1939 multiplexing?
This could be very helpfull if it did catch something there.

Does the ECM show switch status for any of the problem switches in the data monitor?

All the settings you posted look correct, other than the source addresses, and it still puzzles me why there isn't a parking brake switch setting under the multiplexing options. the CM2450 I have a image of has it in there, same as all the CM2350's I have images of.

Also to note,
Source address 39 is for VECU, 49 is for CECU.
Somewhere about 2020-2021 Kenworth/Peterbilt stopped using the CECU and went to the VECU. but for the cummins option it acts the same as the CECU did.
