I got in the truck this morning to go to work. I turned the key and the starter turned, but it didn't start when it normally should have so I let off. I did the same time twice, more and it started. Then I noticed the check engine light. These are the codes I got.
p1610- loss of pzm serial data
p1612- Ecm incorrect coding
U1000- CAN communication line
U1001- Invalid/missing data for primary Id
Got an apointment for Saturday morning to get it checked out. I cleared them in the mean time. Just wondering how serious this is. The truck started fine every time afterwards. Any help would be apreciated.
