i have a good scanner, what can i look for as far as control modules testing? I can touch the positive cable going to the starter with a test light or a multimeter, is there anything we can confirm there? I know it is difficult to diagnose it without removing it, but that is why I have posted my question...
please do not forget to CLICK ON a positive rating
you need to assess the start signal, not positive cable power, so no, you cannot verify anything from the positive cable.
a factory BMW scan tool is required for this type of diagnosis, a third party scanner won't be able to do it
I am sorry, but there is no short cut to verifying this. I trust that my honesty is appreciated.
well, my question initially was that i need to confirm that the starter is the problem. This doesn't really help me out in any way possible. Please opt out and let someone else help. There is always a short cut. So every indy shop is going to remove the starter to test it to confirm? Doesn't make sense. Thanks anyways.
