Saxo 1.1 MA3.1

[kamaz007]

Hello,
I have a problem with Saxo 1.1 driver Bosch 0 261 204 788.
Immo was decoded by removing the clip from the battery while the keys were in the ignition.

I read 93cs46 from ECU, do dump in immokiller and engine still does not start. (first 5 field to 00)
I tried the second ECU and the same. I took the eeprom out of the driver and the same.

I will check all power and shaft sensor.

Do you have any ideas?
Maybe the problem is that the driver with the immo locked by removing the battery terminal can not be started (even after turning off the immo)?

I will be grateful for any ideas. I am sending the original dump.

does this car has keyboard for entering pin before start?

write this file and start car

[immokill]

Add in the first memory address 24 zeros and disconnect the immobilizer and start without problems.
000000 00 00 00 00 00 00 00 00 00 00 00 00 xx xx xx xx


EEPROM 93CS46






You add 24 zeros in the first address, you record it in a 93S46 memory, the 93C46 does not work because it does not have write protection and when it is contacted it is immobilized again.
One time you engrave leg 6, you raise it to the air and you make a bridge for leg 5 in that way you can not rewrite it.

I mean: battery clamp was removed when the key was in the ignition switch. - then immobiliser blocked. Sorry my eanglish is s*itty.
No, does not have a keyboard.

Rafał, i check and let know if works.
My file off (from immokiler) have 0 from 00 to 05, your have from 00 to 0B - maybe immokiler have wrong solution.
Yes, i tried in 93cs46 and 24c04WP but with zeros in other places.




93s46 need a bridge to wp?

Thanks for help. I'll try it and let you know if it works.

EDIT:
I write a dump from Rafał. The car still does not start. I tried with and without immo box and the same result. I read a 93cs46 and is still the same as i write (file from rafal 24 zeros).
I checked a shaft sensor in osciloscope and is working.
Any suggestions?

Try all ff ff or remove eeprom and try

[kamaz007]

Unfortunately, FF the whole eeprom and desolder eeprom don't work.
I will try to cut the pin 22 and 34.

EDIT:
Cut pin 22 and 34 don't work.

This is the immo box 594003 I'm right?

[rafal]

are you sure is immo problem ?

[kamaz007]

The problem arose when the battery clamp was removed when the keys were in the ignition switch. Then the engine stopped running.

I do not rule out that the problem is somewhere else. I checked the voltage on the ECU (pin 18), ground (2, 14), shaft position sensor (30.11). The driver does not connect with the diagnostics, (there is +12V on the obd socket but no connection.) The fuel pump does not start.

EDIT:
Fuse F10 has no voltage, problem was in the fuse box. 24 zeros solution works, thank you all for your help.
