Ford Focus C-MAX sync lost?

[xoom]

Hi, got one car to check why it not starts.. and it was checked before me (2 man told that need new ECU)

So car owner got another ECU and they tryed to clone it (unsuccessfully) eeprom ripped off with tracks and not even in the ECU.. atleast its donor ECU.

Car is Ford Focus C-max 2006 year 2.0 Diesel with SID803A ECU. I read it ok but i think PATS is lost sync.. Red Light stays ON for a minute then blinks 23 code and there is fault codes about data mismatch.

Can some1 check if its synced or not here are files from ECU and IC


And if possible make them sync to ECU

as far i can tell from Ford all in 1 soft there are different sync values:
CED02E3DAD47B9EE - ECU
02960FEB6139880D - DASH

Strange.. i can write file that Ford_all_in_one software produces but not yours :) your file gots changed after write (verify error). attached file that i can write and verify correctly.. not sure what is going on.. feels like ecu changes your file in eeprom after write.

remove the EEPROM of the ECU and save programmer

that's what i'm thinking to do :)

will see how it goes :)

re-synchro perform with the device

[xoom]

which device you have in mind? :) its not possible just via eeprom?

Ok wrote file directly to eeprom.. verify successful.. but result same.. cranking but no start..

read ecu and dash errors

[xoom]

PCM Fault code:
P1621 - Immobilizer Code Words Do Not Match
- Present

IC Fault Code:
B2139 - Data Mismatch (receive data does not match what was expected)
- Permanent

Red light also flashes same as before 2 - 3 (code 23)

write eeprom to ecu i read error ecu and dash

also wanted to ask.. does sync value in dash changes also every ignition cycle?

Ok tested second file. Here how its went:

tested last night to write your file but ecu did same thing.. changes eeprom after write.. so i left it for tomorrow.
today tryed again to write my file that is produced by ford in one soft.. it writes and verify ok but no cranking..
then tryed to write your second file again.. surprisingly this time write and verify was OK.. went to test to car.. it cranks but no start .. same fault codes.. red light always on. And after like 10 ignition cycels it blocked starter again..

try it...........

Yep.. Worked like a magic :) Light go off - Engine Starts :)
