Hi!

I have Ford C-Max from my neighbour with immo problem.
Ford Focus Cmax 2007y, 1.6 CDTi 115 PS.
Car was driving normally since few days ago, when while my neighbour was driving to shop - at the beggining of problems ABS and ESP light came on then, after about half minute car died. And don't want to start any more. He towed car to home and ask me for help. Connected Forscan and there is:
in PCM - P1621-64 Immobilizer Code Words Do Not Match
in IC - B2139-60 Data Mismatch (recieved data does not match what was expected)

And no others errors... But... Immo shouldnt stop the car that is arleady running, right?

Tried to make an PATS Programming. The window with PATS option say that there is 2 keys.
Also there was a help window, and there is info about fuse F46 or F68 in GEM. Hm, there might be something, since rear hatch is opening again and again. Ordered an GEM whith exacly that same numbers and replace it. Tried to start - not even move a starter. Immo light (red dot in middle of instrument cluster) stay on for 1 min, then blinking code 23 (2 blinks, short pasue, 3 blinks).

Security access is granted, but nothing can be done - everything fail. After that need to wait to acces it againg (20 min?)

What might happend? Any advice?

Thansk in advance!

Ok, but just speed clock or all?

Edit:

Ok, removed, cleaned black connector, resolder pins from black connector and... nothing. Car is still dead

Edit2:

Neighbour found his second key and now i can use "Erase key" option and then "Program ignition key" option. And it worked. Programmed 1 key, passed, programmed 2 key and passed. But car still not starting. Can Engine ecu be dead? But there is a communication with it.

How does IC communicate with PCM? Via Can?
