peugeot 406 immo off

[uferi]

Hi mates,

I need help to make immo of on this model:
Peugeot 406 y2003 RHZ 2.0l HDI
ECU 3 plug Bosch EDC15C2, Bosch code 0 281 011 338, Peugeot code 96 491 581 80.
The eeprom is a 5P08C3 SPI bus eeprom, and I tried with immo off software to turn off, but doesn't work.

Bosch "ECU 0281011338 edc15c2_orig.bin" is the original eeprom dump read from 5P08C3 and the "Bosch ECU 0281011338 edc15c2_off.bin" is my try which doesn't work, read the ECU by diagnostics report P1517 error code (Coded anti-start function) and the car doesn't start.

Please help me with a solution!
Best regards,
Feri

Hi,
I tried to start the car without eeprom, doesn't start and the diagnostics read the next error codes:
P0603 ECU fault or configuration fault
P1517 Immobilizer coding error
P1519 FRIC - Engine cooling problem (Now the radiator fan of the car always running at the maximum speed)
P1613 Coding error

So this solution is possible works on some ECUs, but on this item doesn't... :(

Best regards,
Feri
