[ernesto1670]

Hello friends.
I have a Citroen Xsara 2000
When programming km (ejm: 300,000). and put the dash in the car, keep the miles program, you receive the previous miles.
Something I'm doing wrong
I can help

Thanks
attachmen pictures dashboard and memory

Are you sure ,is this car without BSI ? 2000must have BSI

[ernesto1670]

maybe
I?ll check
thanks

[cheero]

this dash work with BSI module,
tested easy
set km in dashboard and dash on:

black
PIN 16 - GND
PIN 15 + 12V

light your new km without problem

install in car and light old km

in BSi is NEC procesor

[cokolo]

If there are two buttons on the panel to reset the daily miles and setting hours, must have miles and BSI. From my experience:hmmmm2:

[almeida]

hello,
when you turn the key on, if you see the oil level with the circles, you have bsi for sure.
and if is hdi is bsi for sure too....

Hi! You can do as your wish. But i use the first.
And first reconect Dash and after bsi.

[almeida]

if you realy have bsi,
first disconnect battery is better.
and put bsi to 0.
you must put really 0000 at the bsi not fffff at the milleage logo
cheers

We continue with the problems.
When I read the memory of the bsi, with digimaster
appear instead of actual miles, this message appears ... (See picture)

Sorry for my English

[rcvantonio]

BSI is also the Nec? or have a 95040 eprom...

Someone can help me with this problem? (See photo)
I can read this report with another device other than the Digimaster?

I very much appreciate your answers

[almeida]

do you have other tool to read the bsi?
like upa or xprog?
maybe digimaster have some bug with that car.
if you use upa, you could do that car 100% safe.
remember is important, disconnect battery, and put bsi to 0
and in the place the milleage put 00000 not ffff
cheers

I have X-PROG and UPA, but with these tools, I have understood you can not read the MCU, NEC.
Would have to buy a tool to read the NEC MCU

Thanks

i would reconect bsi first and after dash if i was you!!!

sooorryy i was trying to say firts BSI and the DASH

ernesto you can use digimaster as a stand alone nec programer enter in Programmer->CPU Programmer-> NEC -> uPD 780973
and edit dataset as almeidas says

[almeida]

if you use upa to read and lift pin 10 11 12
and remove the resistor.
if you do that sure you could read.
don?t forget to erase the bsi.
see below

Ok, thank you very much.
We are moving slowly.
Herewith the result of reading the MCU, I read the DIGIMASTER.
I can help with the programming of this reading. As the MCU of the BSI, I think you should plan 0000.
Thanks

[ernesto1670]

After staying almost hairless. (I know I'm clumsy)
Logree read the MCU, the UPA
File attached.
Someone else can change to schedule and complete my work.
Ex: Dashboard : 140000 km
BSI: ???????

Thanks

[almeida]

i think your dump is bad.
you read with upa?
you lift the pins?
you make verify and they show some erros?
cheers

[almeida]

try not to compact the dump file, when you send that

[ernesto1670]

try not to compact the dump file, when you send that

The UPA does not signal any herror. Reading makes no problem.
Apparently this well.
tks

Hi mate, can you upload the original dump dash and BSI and tell me how many Km you want?
Are you sure that the dump you uploaded is the original BSI? You haven?t changed anithing on it?

Try this for BSI but I need also the dash dump for change your desidered mileage.

hi,try like this:
Car type: Citroen Xsara - (Dash+BSI) - 93c66 - 2000-2003 years
The mileage is stored in the dash and BSI
Dash manufacturer is VDO, BSI is made by Siemens
First reset mileage in dash as shown here:
0160: xx xx xx xx 00 00 00 00 00 00 00 00 00 00 00 00
0170: 00 00 00 00 xx xx xx xx xx xx xx xx xx xx xx xx
than calculate the mileage for BSI:
0010: xx xx xx xx xx xx 00 A0 86 01 xx xx xx xx xx xx
0040: 00 A0 86 01 xx xx xx xx xx xx xx xx xx xx xx xx
0150: xx xx xx xx xx xx xx xx xx xx xx xx 00 A0 86 01
where the next bytes:
00 A0 86 01 - is a mileage

I think you are wrong mate.
Both (dash+BSI) has a Nec MCU!! no 93c66 eeprom, so your solution is no valid.

Regards

[grinovsky]

Car type: Citroen Xsara - (Dash+BSI) - 2000-2003 years
The mileage is stored in the next lines:
Dash manufacturer is Sagem, BSI is made by Valeo
Dash chip type is NEC uPD 780973, in BSI you must find NEC uPD 780949
00E0: xx xx xx xx xx xx xx xx xx 09 0E C0 09 0E C0 xx
where the next bytes:
09 0E C0 - is a mileage

In the BSI put 00's as shown here:
00C0: xx xx xx xx xx xx 00 00 00 00 00 00 00 00 00 00
00D0: 00 00 00 00 00 00 xx xx xx xx xx xx xx xx xx xx

for some models works this one:
00C0: xx xx xx xx 00 00 00 00 00 00 00 00 00 00 00 00
00D0: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
00E0: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
00F0: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
