Managed to read as PA28F400
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!!

how take of the metal cover to take of the 28f400?
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.
thanks for advise.i see in somw forum that solder up tp mcu aluminiun cooler .if i put in mcu and in 29f400 works?the same problem have and the rem?have same mcu inside?and when hot not work?and the dash?everywhere was a motorola everybody have problem.in dash or anywhere .motorola the best mcu in world.without motorola we don t have job
Dear Sir,
I have V70 year 2003 that CEM module is bad now.And I will buy used CEM with identical HW number to replace the old bad CEM.
Please advice what to be done..?
Do I need to copy memory of 28F400..? Or need to copy MCU content too.?
Best Regards

Only 28F400
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.
My CEM has AB28F400 but I have PA28F400. Does it can be replace with AB28F400.? And when read and write, does it to be binary format. I use Wellon programmer.
ask ad bin. here but solution in private to protect our business and customer integrity
I'm looking for CEM 28f400 BDM tool. Maybe somebody can help
