My motor home broke down on Tues night on the way to Redding, CA for a bracket race. This is a 40' MH and 32 trailer so they sent a Low boy for the MH and a wrecker to tow the trailer. The charge was over $6000 and Coach Net covered it all, best $249 per year I've ever spent.

It appears to be ECM on the Cat C9. We were hoping it was just IAP sensor but it's not. It stuttered like 3 times then check engine and shut down. The shop went through harness checks etc and everything points to ECM. It threw codes for all 6 injectors along with some others.

I've never had Good Sam towing but Coach Net was constantly checking in to make sure we were OK, status of the tow truck etc. I was very impressed by them.

If and when you get it back. Ask specifically what the warranty is on the new or reman ECM.
Get it home.. Open the battery compartment and "Closely" examine "All" electrical connections. Even a tug test on the connectors . There may be ECM fuses in that area that powers up the ECM on the injector side. The importance of maintenance in this area is critical.
I can't even tell you how many calls i get where as the ECM fuse blows in this area. If in fact it is located there. Same with the class 8 trucks.

I have Coach Net and have been satisfied with the service. Had Good Sam but they turned it over to All State, I think, and it went to the sewer. I like the way they hauled your unit.

The shop did that as the very first thing. I broke down on Tues night and it was hot out, while waiting for the tow the next morning and 52 deg wesather I tried to start it and it fired right up. It ran totally normal for about 10 minutes then shut off like I turned the key off.
It did the same exact thing the next morning. The tech was hooked up to it and no codes but when we tried to re-start it, we got codes on all 6 injectors along high oil pressure warning and baro code.

Curious. The injector codes weren't 72/73/74 of what you recall? When active? In a lot of instances where it is repetitive and constant on the above numbers, The injector driver module located inside the ECM is at fault.
Part of the ECM. Specif high voltage/low voltage errors.
This module is what converts DC to AC and powers the injectors.This message has been edited. Last edited by: TD3550,

Yes that is what they were and that is exactly what the tech said as well.
