Peterbuilt help

Got a Pete with a cm2250 14L that the cab controller has been flashed with the wrong software. Its causing a 0286 multiplexing fault and cruise does not work. The cruise switches show to be working in Insite. Is there a way to get proper flash and parameters for the truck computer with out going to dealer truck is deleted.

Likely just a configuration issue, is advanced ABS enabled, Traction Control?  Or parameter incorrect on Cummins side. How did this issue start?

maybe take the cab controller out and take it to the dealership and see if they can flash it with correct software? what software does it have in it now vs the software that it actually needs? maybe just needs a couple parameters changed in the cab controller? that's my assessment of the situation.

ill do it

The issue started when the mechanic tried to connect esa and it wouldn't let him. Said it needed to be updated or fixed. It was flashed causing this problem.
I turned off abs and traction control still having same issue.

Multiplex codes are reported by rhe module that didn't recive the expected signal from the network, in case of cruise control a component that depends on the input it will not work
2 Fix it simply find out what is missing, let's say park brake you need 2 look in insite to see who is reporting rhe signal over the datalink and make sure it's correct then use ESA make sure it's avalible and correct
Why did you disable ABS and Traction? Put it back on

Certain updates enabled Stability and Traction control when the truck was never equipped with it.  I'd see if Advanced ABS got active, it uses different Sensors for detecting brake application.

Open insite 
Advanced ecm data tab  > j1939 fault codes 
From there  can see if its a parameter issue or a communication issue

I use legit version of esa and after flash will reset parameters to factory… therefor no traction control issue ….
Otherwise yes 
Advanced stability control
Traction control
And sometimes advanced abs system get activated
