This is an ideal How to do odometer correct for Ford Fiesta:
Here you are:
MCU 9s12hz256 , xprog – upa read/write with no problems
Here it the pinout for xprog or upa:
This one is different, I have
MC9S12XEQ384
Mask 1M12S
Now is easier to you, check picture, perfectly:
Also, almost any team does it for obd.
for example:
X100
OBDSTAR Mileage
X-TOOL
IPROG +, PROG
Some ask to remove Battery several seconds.
It is also possible to do it by J-tag with any team.
upa, orange5, Xprog, smok, GC100, among others.
that have the MCU 9S12 supported.
Thanks
