xxdeh inc Posted January 20, 2022 Share Posted January 20, 2022 Went to start truck but it wouldn't start. Cranked for some time until eventually it dead or so i had though it died must have activated a relay. I put it on a basic code reader a code came up U1146. ( only code) I tried google it but it wouldn't pop up with a direct problem. Main them comes up is tcm / tcm connection. Would that be a reason for the truck not to start. When I it did have problem I assumed it was the started by the way it cranked. side note two weeks before the truck had an oil change at dealership. all was good. no codes but the bolt light was activated on the dash board and has but every time we take it get check no codes seem to come up. I don't understand what's wrong. Quote Link to comment Share on other sites More sharing options...
