Hi everyone, got a little problem and wanted too know if anyone had this before. On my 2007 Volvo vnl 670 when I turn my keys off and take them out. The dash lights stay on and gas gauge and air gauges shows reading as well. I can only get them off by taking out key switch battery fuse. When I put fuse back in without keys, it does ECM check and dash lights as well as gauges comes on.

Maybe a bad key switch?

That is exactly what I was thinking. Found some resources for the issue and will be testing the resistance to see if it is in fact the problem. Thanks for the reply, like to hear other peoples thoughts, helps a lot in resolving problems.

Bad key switch it was. Probably about the easiest thing I ever done on this Volvo Vnl 670..
