I am at a loss here. I have my obd2 wire from pin 58 going to pin 2 0n obd port 4&5 grounded and my constant 12 volt hot. Hook up scan tool and nothing tool works on my other vehicles. I get a green light on plug when tool is plugged up but will not link to ecm.
Anything i am missing as of now i don't have a mil light hooked up is this my issue?
