did you have these problems

 

Nope...
Being a wiseguy..
Need more info to have anyone try and answer if this is a problem?
Start by filling out your signature? Truck? Year? Modifications?
When did this happen? After doing work? Adding a box?
Mileage? Etc...
Stating you had 3 codes meant nothing to me..
