Flagship one pcm question
2003 grand cherokee limited 4.0
when I bought this jeep 3 years ago the pcm was bad so I bought another one from flagship one. The cooling fan wasn't working at the time and I had it wired to where it would come on and off with the jeep running. I finally decided to fix that issue but now the fan still will not come on when it reaches temperature. Now I'm having an issue with the abs and brake light ( showing 5 codes but one is a under voltage) (replaced alternator 2 months ago)
question is will resetting the pcm clear the refurbished pcm from flagship one or will it stay programed to my jeep?
resetting method where I take the battery cables off and touch them together 30 seconds and so on
