I have recently starting throwing a DTC every time I tow heavy. There seems to be no impact other than an continuing annoyance of the overhead dinging and See Dealer Now message about every 10mins. Anyone else had this DTC? I have searched all forums and really haven't come up with much. Also my Edge Insight Monitor sees the DTC but is unable to clear it. If I reflash the EFI tune...it will go away until I tow heavy again. Any help would greatly be appreciated...
