Peugeot 308 Dash No Working

[ecupro308]

Hi To All Member,

My story was....

First, the dash is working fine on the bench.
Then, I program the chip 95020 which is inside the dash ( Basically change the mileage )
I also program the chip 95128 which is inside the BSI ( Basically change the mileage also )
When I power down the BSI, the mileage was update to the dash. So far so good.

The understanding calculation on dash is ok for me, but not the BSI ( the last two bytes before the four bytes which change the mileage )

After some bytes have being change and program the chips, the BSI and the dash reset itself when I power up. ( the relay on BSI keep on and off, and so the dash blinking.

Then, program back to the first try, the BSI and dash seem to be ok ( no reset by itself this time )

My problem is, the dash can not display mileage. ( it only display service symbol with "------",engine oil with "--", then final display is '---------' )
No mileage was display on the dash or update.

SO, members, is my dash died or can some one help me out.

Thanks in advance.

Regards.

Dear Sir,

Thanks you for the replay.

I did reprogram the 95020 and 95128 which I start from the first place.

The dash not working.

Normally, if the BSI's mileageis higher then the dash, the dash will be update the mileage from the BSI.
if the dash's mileage is higher then the BSI, the BSI will be update the mileage from the dash.

Sir, do you have any solution that i can try ?

or Any members please.

Thanks in advance.

Oh, yes.

Sir, I notice that, when i power up the BSI with switch, the dash seems to be tak longer time to initialize and display Service symbol with "-----", Oil with "--" and finally "-------------"

Did i corrupt the firmware in the micro controller ( the dash ) ?

Thanks in advance.

Dear Sir,

Yes, i desolder the eeprom, 95020 and read ( same as BSI,but different eeprom,95128 )

First time it work. ( BSI's mileage 102880km, dash's mileage 105868km )

After change the mileage on dash, 105880km ( BSI did not change mileage ) for second time, it still working.

Then change the mileage ( from 105880km to 49000km ) on both, eeprom, this time BSI doing on and off when i power up. ( look like the BSI reset )

This is the begining files.

Can some one change the mileage to 49000 km, please ?

Can some one help me for my lovely dash, please ?

Thanks in advance.

Regards.

Hi frankrayk,

I understand how to calculate the dash value.

But for the BSI's value, "10 7A 07 00 E0 74", i don't understand the last two bytes how is being calculate. ( E0 74 )

Can you please tech me how is being calculate ?

Thanks in advance.

Try to rewrite original files and verify if it works
In the case it works try again to change values
Good luck

Members, you know what happen, i made a mistake. I put a wrong 10 pins socket.

The H-CAN and L-CAN wires should connect on BLACK socket but i connect them on WHITE socket. What a joke.

Now it work.

Thank you berciumihai, frannkrayk and others.
