Hello,
I have a problem with Corsa 2007 year 1.2 . After crash in driver side alittle bit car haved airbag crash data storer, I cleared ,but dont start in
car engine are this faults i tested with bosh kts 670 :
P1632 Transponder key malfunction.
P1678 Engine management identification faulty.
P1679 Communication with central electronic incorrect identification received.
When i connect to immobilizer he wrote : haves 2 programmed keys, and all values are good , but
When i put a key and try start relays activated, but starter dont work and car doesnt start.

Hi,no damage was deal only in driver door.
were location impact sensor under driver seat ore how old opel in door?
but SRS show's what all airbag units all good.
Have you tried to reset every thing and program back in? could be possible ecu fault though

Hi,
yet I did not a nothing, I do not want to touch the original programs and waiting your suggestions.
ETC... and for this model I do not have the proper equipment for block programming.
Did you check to see if these faults were there before you cleared the crash data?
To me it looks like someone's changed an ECU and it hasn't been coded in:
P1678 Engine management identification faulty.
P1679 Communication with central electronic incorrect identification received.
If the ECU's aren't coded to each other, then the code below isn't much of a surprise.
P1632 Transponder key malfunction.

Yes this faults was before i cleared crash data. But Ecu vin look's same.
sorry for my English
failure seems connections
must eliminate all accidents breakdowns
encode and match the transponder with the ecu and bsi

Thanks for your answers.
I cheked all wiring all are good,all fuses and relays are good and working.
I can read security code from dashboard ? and this code need put in to BSI and ECU?
Ore need special equipment for this job?
Now i have Tech2 ,and i try to reset ECU and reprogram BCM, but then I try this funkcion, i can programm Airbag ,write what security code input are wrong, what I must to do now?
Can I read Airbag ecu and from eeprom read a pin code?
Please help me.

read pin from dash and then swap bytes, i.e pin is just before vin, so if it read 4576 your pin is 5467 ok, plus sometimes you read the pin may be 5 digit i.e.35647 just use the last four so pin is 6574 ok, i think either you input pin wrong or bcm no good, read my posts on corsa d my friend

Yes i read a dash eeprom , and found pin 3774 if 'am right. (I put a file if you can can you look for 100% ).
I reset ecu ,and try reprogram BCM ,but when BCM try program SRS write what security code are wrong, maybe need input in srs good code?

Maybe some one know in what line need to look, and need swap a bytes?

PIN seems ok
Try this way, need to follow as prompted
1reset ipc
2 reset bcm
3 reprogramme original key
4 reset airbag module
5 turned off ignition for 30 seconds
6 programme the ipc
7 programme the bcm
8 programme the airbag module
9 read and clear all fault codes
10 ignition off 30 seconds
11 START CAR
If this dont work there is another way

Thank you for your response.
Maybe you have instruction ore can tell me how reset with tech2 ipc and airbag ecu ,because i dont find ,
I only find how reset ECM,BCM and how need reprogram keys,transponders.... etc. but this i cant find.
Thank your reply.
