Cat 3126 ECM programming?

Recommended Posts

My 2003 Fleetwood Providence, Freightliner chasis, Cat 3126 engine, stopped running on I-35 in Iowa last week.  After a tow to a local shop, teoubleshooting revealed probable ECM failure.  ECM was taken to Catepillar in Altoona for check.  Result bad ECM.  New ECM sent back and installed.   

Now I need the new ECM programmed.  Who would have the proper/original program?  Fleetwood, Freightliner, Catepillar?  The RV runs, but no cruise control, no speedometer calibration, etc...

Waiting on return call from Zeigler Cat to see if they will finish programming the ECU.

Thanks for the help,

Pat

Pat, A Cat dealer would be your best option. Most others could do it but only with CAT SIS software. Locating an RV dealer with the software and skill set to do it properly would be a needle in a haystack.

Im actually surprised they didn’t complete the programming prior to releasing the coach back to you.

Thanks for the input.  The Cat dealer afternoon shift stated that they no longer work on motorhomes.  I am still waiting on a call from the shop supervisor.  The truck repair shop didn’t have the Cat program to complete the programming.  I hope it all works out with a phone call and a trip to catepillar next week.

I am learning way too much about this.

Ya, with the very limited access to the engines on many motorhomes, not working on engines is understandable.

But, the programming the computer???????

My Cat has access to the ECM in the dash and in the rear. Surely most diesel powered RVs have the same. Sounds like jerk at work. They are a Cat dealer so why could the program be downloaded? Or is that possible?

The tech has a plug in program...had it done on my Cummings in Gillette.  He plugged into my dash & 5 minutes later, my RPM's where compatible with my Allison....now, I can climb hills again! 😁
