yes I have your answer seen this vast times and know how to find this. first off NO
COUNTRY TOLD at all , not one clue and PCM are not the same world wide, for sure the
OBD2 or EOBD jack.
The USA car pin 16 OBD2 jack is power +12vdc, hot..

if not the fuse to that pin is blown
FOR SURE.
or not using OBD2 2008 newer scan tool the old tools can not do
CAN_BUS comms, in fact the pins are missing if you look.
pin 6 and 14 must not be missing on the tool or dead.
if the car warns you any bulb on car is out,it has CAN_BUS
CAN has been a standard on some US cars and light trucks since
1994, but it wasn't made
mandatory until
2008 (2001 for European vehicles).
CAN_bus here. (the best tools are 2008 up) IMO> !
and this ISO spec,. CAN.
1898-5:2007 , (best )
this is why 2008 cars have and JAG and FORD are married.
