Volvo V70/S80/S60 1999-2004 CEM Thread

[pundravac]

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 ?

Johnype,
You want to ell us that you read those 28f400 in circuit?
Can you post a picture how you do that, please!

[strassenfeger]

Yes, a picture would be great.

[Tomanio]

Yes, old CEMs have pinout for bdm- flash can by read thru MCU.

[pundravac]

Tomanio,
Which programmer you use to read this flash through MCU?
I only found USprog for that.
It will be ok to find some cheaper solution for those old Volvo's.

[strassenfeger]

Does anybody have the pinout for bdm connection and want to share it?

Hello. I've got similar problem. All key lost situation, CEM data looks corrupted, Tango doesn't recognize the file. Flash is Micron MT28f400B5 and programmer Wellon VP-480. Anyone has Codecard.lt volvo small program and can check my file?

Wrong readed or flash is damage.

[bobbik]

Flash is broken, tried another prog, readout is different, but also wrong, Codecard.lt program is useless too-Tango doesn't recognize the file. How to repair it? Put similar dump with changed VIN and make keys with Tango? What about CEM config? I've got VIDA substitute without online, but car is far away from me, i've got here CEM and ECU only.

I am looking for 24f400 dump
CEM :HW-pn 08688513 30682664 date of production code: 04W226
Car is S60 2004 2,4D5 5-speed manual gearbox.
I'm gonna to rewrite Vin directly in the dump, then add keys by Tango and make a synchro using Codecard.lt small program. I'd hope car will start, then we 'll see what doesn;t work properly.

[bobbik]

anyone? ......

After few attempts with different chip ID and voltages i've got something that Tango recognized. Of course there is no synchro, but that's piece of cake.

[bobbik]

Please who would share with easy read/write
solution without soldering?

Can Willem write back to the flash witout problem. I like to know what tool can write back without problem starting.
Thanks for your wealth of knowledge
