ISB07 6.7 high exhaust temp light
I have an ISB07 6.7 in BB vision and the high exhaust temp light keeps coming on he has done a regen. It has been back to the dealer a few times for this problem. They end up replacing the ecm for lack of cummication. Just got bus back after ecm replaced and a regen. Now high exhaust temp light is back on can you all give me some ideas of what can cause this light to come on. One more thing there is no DTCs
