Good evening all,
I have a 2012 Chevy Colorado Z71 that gives a P0606 and P0607 code after I read it. It has an aftermarket radio that has been disconnected to make sure the battery voltage doesn't drop. I can clear it and the permanent code goes away after a few drive cycles. Everything works fine afterwards. What can I look at to get this to stop happening?
Thank you,
P0606/0607 dtc's are often a sign of a failing ecm
Thank you. I'm thinking the aftermarket radios can bus interface device may be causing the issue. Thank you for the help.
Looks like it's a common issue with E67 and the presence of the Class 2 bus in the vehicle.
I've got P606 when reading from completely stock H3 and no DTCs while writing.
I see nothing to worry about, just keep in mind this peculiarity.
