Ford BCEM JTAG help
​
I am trying to get to the JTAG of a Ford BECM, It is a C-Max BECM, but they are standard across the Fusion, Focus and other Ford vehicles.
I would like to see if I can get any additional information from JTAG that the CAN Bus is not giving me or get access to to read the firmware on the chip
It uses a mpc5534mvz80 chip, but there are no silk screen information points on the board at all. There is a 51 pin test area though.
What is the best way to start pining out the JTAG and is there a preferred probe.
Thank you,
Rick
