Car is Opel Corsa 2001 with two airbags
Everything worked ok, till some day airbag light shown up on intrument cluster.
I tried to connect to airbag module but without success.
Finalny i tried to connect to it directly thorough pins, but also without success.

I think it's dead. I want to replace it.
Can i buy used one ? I know it need to be same model, configured for two airbags, is that all?

I have only opcom interace and universal interface.

Check the voltage supply and earth for module,and all is ok,check the pcb for corrosion.Yes you can use other one with same hardwarenumber,read the eeprom file and upload for other.When you find same config module just the VIN number dont match when you read the identification numbers

I forgot to mention that i have checked voltage and ground.

if fault was caused by corrosion, and i will clear it up, should i use this module ?

which tool do i need to read eeprom ?

[banoo]

Clear it with izopropil alcohol,and with one toothbrush,and check it.With this can't you trouble making.The eeprom can read with carprog maybe,not sure,upload the serial number or photo

I took it out of car, it does not have corrosion
it looks like new inside,
i tried to resolder all soldering points, but nothing changed, it's dead

I need to find one with same GM number?
I read somewhere that only two letters in upper right are important.
On mine there is DS

You have MC68HC08AZ32 chip,try this read for look what is inside.With X-prog,etl programmer or carprog can do that.When you choose the donor unit,it must be same configurated

Thanks for answer. Currently i don't have xprog or carprog.
I have found corsa with same configuration: two airbags, two seat belt tensioners.
If unit form this car has same GM number, is it enough to work in my car?

When the hardware number match its OK,everything is the same.

Now i've got two airbag unit both don't work in car
What i have checked:
1. Airbag unit has ground and voltage in harness
2. Diagnostic line between airbag socket and obd socket is OK

Now i want to test it on table
What do i need? Voltage, ground, obd connector is that all?

Pinout:
Airbag 30 - Obd 8 (diagnostic)
Airbag 5 - +12v (ignition key)
Airbag 7 - Ground
Obd 4, 5 - Ground
Obd 16 - +12v

Is it all i need?
I've got opcom and opel scanner to test it, also standard KKL interface

With multimeter check you the power supply in car?when yes,take one 12v/21 watt bulb and check with this.In attachment sended the wiring,but you have the correct pinout.With OPcom must be worked on bench
