Does your ESN end with an SN at the end? Like CM2250 SN?

I've never worked on any of those systems unfortunately.

But based on the fault code tree I found a service bulletins regarding the air assisted pump. Search TSB200096 on Quickserve.

Yes. SN at the end. Mexico truck. I will take a look at bulletin. Appreciate it.
