CAT C7 ECU programming

[Motorhome05]

We finally caught up with our mail and it contained a letter from Freightliner telling us that we need to have Freightliner reprogram the ECU unit. Apparently some of the Freightliner Custom Chassis XC, FS65, and C2 models manufactured between July 28, 2004 and December 2, 2004 the ECU was programmed to derate and shut down automatically when the engin begins to overheat. So, luckily, there is a Freightliner dealer about 30 miles south of us on the route we are following. Called and got an appointment for 6:30 Friday morning. While there, we will plan on having them do their MH service for us, which will include oil change, lube, checking out engine, tires, etc. Since DH is not mechanically inclined, this will be great for us.

Don't forget to get your valves adjusted....My
CAT book says at first oil change which is around 10,000 miles. Then you are good til 100,000 miles for the next one. Check your CAT book..I did not believe it either until I saw it in there

Thanks kenbt. I took your advice and checked our CAT book. So Friday, we will have the valves adjusted also. The service man said it would take 5 hours to adjust the valves. We are hoping that this will make a difference in our mileage. Thanks again for answering my message. It is people on this forum who have really helped. I very seldom post, but have learned so much.

Reference Cat valve adjustments - you might want to check further on the mileage requirement. I've read several posts that said Cat had revised their recommendations for RVs to do by 4th oil change or 40,000 miles. You might be able to find this information by doing a search on the forums, or maybe call Cat (thats supposing you reach someone who knows what they are talking about and not just reading whats on a bulletin in front of them.
