850J dozer Ser. 169801. I check for active codes periodically and there was one listed today. It said " Cooler Bypass Sol No Response TCU 522451.5" Does anyone know what this is? As far as I can tell there was no affect on the machine while I was running it and there were no warning or caution lights lit up on the panel. I ran out the day without any problems that I know of.
Thanks
