Tsb 15-0021 CEF
Hi all. I have a 2012 F-250 6.7 liter. DEF system failure came on! P207F Took to dealer and they updated PCM with TSB 15-0021. Truck is running fine, but, I have not seen it going into regen like it used to before the pcm download. Concerns me because I don’t want it to go into system failure while I’m pulling the family RV. Any comments or knowledge in this area would be greatly appreciated.
Thanks,
Chris
