Astra F 1995 - immo off?

[omglol]

Hello!

I have 1995 Astra 1.6, which occasionally does not accept coded key and the engine does not start. I would like to remove immo. Is this possible?

Here are pictures of ECU:

Actually, I don't know what exactly it has. Can someone tell me from the picture of PCB posted in post #1?

It appears to be 68HC11F1 ... is immo there? I can read it with UPA and post dump here.

[LOVEGOD]

just program another key and try

[omglol]

Nope, I want to turn immo completely off, don't have time to jerk around with 15 years old car ... nobody's gonna steal it.

[omglol]

Anyone guys?

[marinero123]

only if you are able to read/write HC11F1 you will can remove immo from that ecu ....

[kevfield]

Hope this can help you ;)

Thanks kev

Thanks! Can you show me the exact location of the 29f010/27c512 in the picture of post #1?

Fill all eeprom off MCU C94R (MC68HC11F1) with FF... disconnect Immo box plug (it's around contact) and car start

27c512 is the last picture.

Tnx! Do I have to lift / cut track to any pin of the MC68HC11F1 (when using UPA-USB)?

[omglol]

Thread bump!

[melcool]

No! You dont have to cut or lift pins!
Only read/write all FF!
Very easy job!

Hi!
Have you tested this?

[melcool]

Hi!
Have you tested this?

Yes tested!

[kevfield]

Me too is easy one :)

[omglol]

I am getting bad connection on wire 6 of UPA - MODB. It says "MODB - 2,47V Bad". Does anyone know why?

[omglol]

OK, I sorted it out. I contacted Elrasoft support and they told me to cut the track/lift pin number 2 (MODB/Vstby) of Motorola HC11F1. After doing that everything worked like a charm!

Hi! I am having problems with this car. After doing immo-off, the car now sometimes turns check engine on and revs drop to 600rpm. OP-COM, Texa and MultiDiag show error 24 - Vehicle Speed Sensor (VSS) - No Signal. But this car does not even have Vehicle Speed Sensor, because it has cable from Gearbox to Instrument panel. Does anybody know what could be wrong?

[omglol]

Solved. Vehicle Speed Sensor is in instrument cluster on this car. Wire (red/blue) from instrument cluster to ECU was cut somewhere ... I put new one and everything works OK!

[xelos]

after take off immo module is not connected to the car speed signal. you need to connect cable, blue / red and blue at the plug in the module immo

hi
i need to turn off immo in astra 1,4 ecu made by delco 16204799
this ecu contains motorola hc11e20 (e22b mask).

does solution with puting FF in eeprom work in this ecu ?

[vladgsm1]

tested this metod but not work,
read after connect vehicle and dump is modified
immo is disconect
read eprom or read all memori ?
