The key may also have a W with a strikethrough to indicate that Immobilizer isn't present. I assume in this case that the security data pin/code is still on the eeprom for BSI coding. None: Cars without Immobilizer will not have a symbol in the instrument cluster showing a key inside a car and will start and run as long as you cut a new key that is able to turn the ignition. So what are the impacts on the BSI? Does the three connector ECU use the flash to check the security code/pin, or the eeprom?ĭoes this mean if you write a different file to the flash on any PSA three connector ECU then the immobiliser won't work? Ie, you'd need to always edit the original file if remapping? Three connector sounds like it has coding for immo/security on the eeprom in an encoded form, which can be decoded to then be able to be written to the flash (if you need to) Single connector had coding for immo/security data on the eeprom. This is a how-to guide manual for Universal Julie Emulator VW EDC15 IMMO OFF/ IMMO ON function.Check below for more details Please make sure before start: Engine capacity: 1.2TDI, 1.4 TDI, 1.9 TDI, 2.5 TDI with W2 and W3 systems, diesel engines from 2000 to 2004, some to 2006, and even 2008 (except Audi with coded pump) Suitable for vehicles with 2-socket ECUs. I'm a little confused about how the PIN is stored and used from single connector to three connector ECU's.
So the eeprom contains data that is checked against the flash, so the data in the eeprom is like a checksum for the flash data too? If you just wont to adapt keys for PSA group PIN can be calculated from eeprom - PIN can be programed to the ECU.
