octavia 2002 1.9tdi bosch 0 281 010 380 edc15vm+ immo off

[mikkhh]

After jump starting car does not start anymore (starts for a second then cuts out). There is key sign lit on the dashboard so I believe it is immo problem, Autocom says that too. So I decided to make immo off 24c04 with EDC15CALC, but after testing the car does not even start for a second anymore. Do I need to make immo off for the 29f400 flash too or try other software for 24c04 eeprom? But the car has cobra 7915 immo installed also, seems like I have to try shorting k11 and k10 lines on cobra immo plug (these have engine x sign on the wiring diagram http://www.autoelectric.ru/autoalarm/cobra/7916-7919/7916-7919m.htm , everything else should theoretically work if I leave it unplugged).

I have attached both stock eeprom dump and immo off made with edc15calc (immokiller makes same immo off file).

So in this BOSCH ECU immo in the flash not eeprom? Only dtc faults were either immobilizer or fuel cut out (can be the immobilizer most possibly, but the aftermarket immobilizer can play tricks too, I will wire it out by just bridging those two wires). But immo fault can be caused by dashboard too or key reader, so it would be easier to just immo off, I believe.

But if it is not immo, why the key sign is lit in the dashboard, so it must be immo issue. Engine run and then cut seems a lot like immo to me. The engine ran perfectly before.

Try this 2 files and press thanks if OK.

Hi !
You can do it with IUD 3.2 which does very well its job on this calculator ...

I want to make immo off, but I would like to know if the immo is only in the 24c04 since some of those Bosch ecu?s have immo in the 29f400 flash chip too. I tried my immo off file on the eeprom on the car too. And the car did not fire up this time with the modified file(before it fired up for a second or so and then engine died, so it seems strange to me, but it might be the afetermarket immo playing tricks(maybe those two wires go to the fuel pump, that would explain a lot, will dig deeper), and will wire the cobra immo out in the evening...). It is not the fuel cut off solenoid wire, since I hooked up +12v to it and still no start. Will hook up autocom for another dtc check.
Only changes to the 24c04 dump are 1B0 and 1D0 line 33 value to 60 value (stock, immo on is 33 value).

Now ecu shows fault codes (eeprom error 18048 for example, 01177 immobilizer off error, 18020 ecm incorrectly coded), seems like the 29f400 has to be flashed too, since only eeprom immo of did not help. It explains why it started for a few seconds then cutoff with the stock immo on file. Now it does not even start for a second.

[mikkhh]

here you have files manual transmission

Will try in a few days.
But for Immo off 29f400 there should be two 01 values that must be changed to FF. Is my assumption correct?

immo off is, EEPROM not need to modify, 29f400


Managed to try it today, 29f400 and both EEPROM are flashed. But still cranks and no start. No glowplug light, has fault codes 01314 and 01177 (will get correct codes with vcds in a few days). I will try returning eeprom to stock and then trying it but to me it seems that ecu is ok, but there is a connection problem with ecu connector or dash connector, will check. 440358 Here is my immo off file for 29f400, should be correct or wrong checksum?

[kiszka]

[mikkhh]

What do you mean by power failure ECU? Ecu dead? Or relay, fuse issues? EDC titanium shows, that my immo off 29f400 file checksum is ok.
Yes but eeprom I can return to original and it should work ?

If auto start and stop it then, it blocks the immo
If there is no start then this is a fault in the car

Yes but my checksum is wrong that is why there are those fault codes it seems to me. At first car started and then cut off and gave immobilizer fault codes. After flashing 24c04 fault codes that said that the eeprom contents are changed.

[mikkhh]

Inspect the fuses, the message PM
440617

All engine related fuses 10, 28, 29, 32, 34, 43 are ok and show +12v, but still no start at all (before modifying files start for 2-3sec then cutoff) and no communication with ECU fault code... Should I check power at ECU connector? Or ECU dead (should I try reflow ecu)?
I think I will revert to stock and then try it out...

Or is it caused by modifying the 24c04?

[kiszka]

..........

[mikkhh]

Flash modification yes
Modification of eeprom does not interfere with diagnosis

hmm but after at first I modified eeprom there were fault codes that stated eeprom contents modified. But if I revert both files to ori then should work(start for a second then cutoff)? Or ecu dead with reflashing??

Or I am not the only one with immo off issues : http://www.digital-kaos.co.uk/forums/showthread.php/118929-Kangoo-1-9-dti-bosch?highlight=edc15vm%2B

What about cutting lines?

I checked 24c04 eeprom before using your mod file and one value was changed.

Can I use other BOSCH EDC15VM+ for 1.9tdi 81kw manual with working immo off for this skoda?

[kiszka]

..........

[mikkhh]

Nothing needs to cut, immo off and start

yes but these modifiactions not work, car not start at all (at first start and then cut). What could be wrong with the files? Should I use immo emulator?
But it seems unlikely that there are wiring faults now since after 24c04 flash car communicated with ecu now not. ECU dead?

[mikkhh]

I gave you a set, save, and start car 300% test personally
440948


ok I tried at first edc15calc for 24c04, chip reads ok and verifys ok too, but no start at all gave fault codes for eeprom error 18048/P1640/005696. Then tried flashing 29f400 and then got error for no communication with ecu. Can the fault be in ecu connector after moving it ie broken wire in ecu harness? Or how much percentage for faulty ecu after reflash (24c04 gets changed by every km so this can?t cause anything) and 29f400 should have checksum etc protection built into it so virtually impossible to destroy ecu by reflashing? Hmm all the fuses are ok and relays seem to be ok too. Can faulty dash cause no communication with ecu?

Can I use random edc15vm+ ecu and transfer my 29f400 and 24c04 data and then that ecu should work for testing purposes? 66kw edc15vm+ should show at least glow plug light for testing purposes?.

tl866 minipro (and have ch341a also from old times :D ), it works ok I have done 25 series computer chips with it no problem and airbag dumps for Civic 93series chip. And I use socketed adapters (clean off sockets and chips with alcohol and apply pressure to them to ensure good contact). Chips verify and read ok so flashing should be ok

and the 29f400 original dump you sent matches so adapters must be good and working ok.441009

[mikkhh]

How big are chances that ecu dead after relashing 29f400 ad 24c04? Near zero?

[Pyromaniak]

saerch for pinout for this ecu, look for 15,30,31 :) (15-igniton +,30 +, 31-) This ecu is posible to kill by reflashing, if zou dont make checksum, car start only one, then ecu is bricked
( no mil no diagnostic connection)... Nedd to be desolder flash and reprogram by programer... I make with tl866 too its good... I think its in electric in car, not in ecu, like say kizska.BR

Yes if wrong checksum then reflash by desoldering and should work ok? Have you seen dead ecu by reflashing?

http://i.imgur.com/lToWW.jpg by pinout there should be +12v at pins2 and 37, gnd pins 4 and 5. Can iapply external power to ecu in car?

[kiszka]

[mikkhh]

But dead ecu quite rare? If all goes well I might be able to test it with 66kw edc15vm+ ecu.

[Pyromaniak]

If you have no power on some pin, look for why is not power on this pin... (some power pins are from relay, this relay control ecu)

This ecu i killed many times by reflashing, when i desolder flash and program with programer ewerything it?s fine... Look for soldering, and right positions on chips(e2p and flash)

[mikkhh]

Thank you everybody for helping I have few updates for you.
So none of the IMMO OFF files worked (no start at all) on this car so I tried reflashing ori files and the car started then cutoff, but there are now no fault codes for immo except for code stating that all are ok check control unit wiring if problems. The car says unauthorized key and total adapted keys are 2. I am going to source new receiver coil and then see what happens if that does not help then I will see how the dashboard connectors look. If nothing helps I will look into immo emulator, there are schemes for edc15vm+ on DK :) .

EDIT: reprogrammed keys and works ok now.

[mikkhh]

The car stopped working quite interestly. There is no power to the fuel cutoff solenoid. The solenoid is powered directly from ECU pin53? Correct?
Can I swap in edc15vm+ from 2.5tdi v6 to this 1.9tdi if I swap the eeprom + flash?
