Sys 41 error- testing the ignition control module
Hi guys. So I have a c41 issue and am testing things. Pin a and d both are getting 12v. Pin b is about .3 volts and goes up around 4.8 (if I recall correctly) when cranked. The ecm and opti appear to be doing their thing.
I heard autozone can test these but none of the stores around me can. I also went to the local pep boys.
Any other suggestions on getting this tested or any additional tests I can run prior to just replacing it?
