Mazda/ Ford CANBUS PROBLEMS

[Specialist]

Wonder how the OP got on with this !

Hope he was using a good Multimeter for testing, rather than a Power probe.
Seen too many people using a power probe for this sort of fault finding & killing off ECU's.

I'd advise him to get a good wiring diagram for the said car, follow it through the problem circuits. When you check the 16 Pin data connector for a live feed don't forget that a ground is also required at terminal 4. Without both of these the scan tool won't power up.
