    Hello
    I have a HUGE problem with the Volvo S80, 1999. 2.4L gasoline
    CEM => INTEL 28F400
    ECM => 5P08
    The CEM recorded errors "Wrong transponder" and "No information from the ECM" Starter does not turn.
    1. I read flash and eeprom CEM ECM (original files below):
    0 261 204 559 (26SA5329 1111 01275781 B 0000029365 98254 H3.2)(5P08C3).zip
    INTEL TB28F400.zip
    2. fixed the flash and EEPROM using a small program from codecard.lt
    3. coded two new transponders (machine Advanced EVO)(repaired files below):
    5P08C3 sync OK.zip
    INTEL TB28F400(repaired and 2 transponders).zip
    4. programmed the 28F400 and 5P08C3

    The time now is such that:
    Starter turns but the car does not start
    No errors in CEM and ECU
    The CEM values ​​immo (VIDA):
    "The data received from the ECU = NO"
    "VIN number correct = NO"

    Probably even though they fixed the flash (program from Codecard.lt) is the flash is damaged more seriously.
    Does anybody strong in the subject can check me this flash?

    Or go to the service to re-programming Volvo CEM?
    But how to do it on a virgin? Delete the 28F400 to FF?

    Help please!! This Volvo is old, but it's very hard player!!

    Metal cover? Simply: use your fingers or screwdriver.
    For metal case: Cut the wall in two corners and bend, You will have better access to flash eeprom.

    I use the BDM method for CEM 99-04, no problems at all to change between different types of flash. Homebuilt parallel interface with old computer and BD32 from Motorola.

    Wrote a few MC68376 Assembler programs that I upload to reflash the 28F Works like a charm and easy soldering, 7points under the box!

    But I would be very interested in the virgin file, is it the same image for any model year 99-04 ?

    Safe to use original firmaware of hardware and copy only software part from virgin image if different hardware number. Model year 99-04 have one part number but many times was changed so it could be the same image for any model.
