Cadillac Repair Questions? Ask a Mechanic for Answers ASAP
You need a scanner that is sophisticated to communicate with antitheft system bcm
I suppose it would depend if it was meant to be a 12 volt circuit at the time. So you have scanned all modules and all you get isa u 1300 code? is that the only code you need info for? the buses are shared circuits so its hard to say
too big a voltage for a five volt circuit too small for a 12 volt. I would stick with trying to diagnose the codes and after that you may not get 6.5 voltages....
ss do an all module scan and list all codes and lets go from there
your question had to do with voltage levels?
alldata doesn't list an u 1300...doesn't mean it doesn't exist it just means I don't have info so I will let another expert help
