Passwaor reset on MEDALLION INFORMATION CENTER

8127 worked for me. However the information I could access was near useless. I was getting check engine light due to a faulty turbo boost sensor. I ended up buying Silver Leaf for my laptop and it is very good. Found the problem in seconds. Plus you can call their very good TS.

Try 8127 as the password.

I tried calling Spartan (mine is on a Spartan chassis) and they had no help for this.
I have not found a password that will work yet. My local mechanic says no professionals use them as they just plug in their own computers. Spartan did warn me that if I succeeded in getting into it, I could really do damage if I changed any values by mistake.

If all else fails:
