good deal,
yes i supposed if everything checked out ok then there is always that possibility that the controller itself may not be seeing the signal in that circuit for some internal reason.
controllers arent cheap though so hope that is actually what it is.
tblsht diagram says to check stop lamp output wire #788 (pin7) at vsm connector, if resistance is less than 0.5 ohms then repair short to ground in harness circuit, if no then replace the vsm.
I ran thru the checks ,removed the assemblies and was told the controller was the problem, thanks
oh yes, check your bulbs, if one burns out it will show an error
thx brewski :o)
what are the letters in the model number after the GLP040___?
I'm sorry my mistake, when I got to the customer found code to be a 880-4
