I have a 93 Ford Thunderbird Supercoupe 3.8. When I connect my Snap-on MT2500 scanner it will not receive any data and codes from the data link connector (under hood). The car can do functional tests with the scanner. I have tested all the pins at the data link connector. Here are my voltage readings on the data lines KOEO.
Bus-@ 300MV (voltage drop).
Do these voltages sound correct? I have snap-on booklet and it says Bus + should be 5V and Bus- 0V.
I have tried two of the same scanners and they both have the same result. I did also enter the VIN correctly. Please help!
I appreciate it.
have the same problem?
