Came back from sledding today,parked truck outside for a bit while i tinkered on sleds in the garage. About an hour went by needed to run too town statred the ole girl up backed trailer up and unhooked. Truck sat idleing for 10 min while i did a couple of things hopped back in and had a check engine light, so i stopped by oreilys and had them plug in and at first we had p1693, didnt know what that was so i wrote it down and then cleared. Then i got p1693 and p0382. Cleared code and left and came home and started reading up. Started truck 3 times since then, no cel and grid heaters seem to cycle normally. Should i chalk it up to a fluke isolated incident or should i dig deeper. Also how commin is it for the ecm driver to fail causing this problem,vs bad relay or wiring issueu
