Last time it came with another code: Loss of Communications with DIM, and this time again triggered the same one along with Pump Motor code.
Question is how to trouble-shoot it. The replies on this forum to my DIM code question imply I need to use a trouble-shooting "tree" which is available only to people who subscribe to some expensive GM service.
I thought things like this would be solvable using the factory service manual.
Any suggestions? thank you.
