1997 F350 Speedo re calibrate HELP!!!!
I am trying to recalibrate a speedo on a 1997 F350.... I read how to do it, I jump the connector under the glove box, I hold reset and turn the key on....
o 08 3
o means metric ( KM/H )
08 is calibration code???
3 means 3 times left that I can calibrate
Now all the info I have found say there is a 3 digit code... and the math I did comes up with a 990 code for this truck... Now if I hit the select button to find the code it comes up with
and so on.... never do I get the option of a 3 digit code....
