LS1 PCM Tuning

Hi All,
I have done a search and found one thread that it is not possible to tune LS1 PCM without using EfiLive or HP Tuner?
Is this correct?
I am wanting to reset the air bag light on my VT 5.7L (LS1) and would like to know if possible. I have read some threads here and they are based on V6.

Thank You,
Jim.

i don't think HPT or EFILive even do the air bag etc anyways, i think thats something you'd need to talk to holden for.

Correct. HPTuners or EFILive will not reset the airbag codes due to they should be checked by a technician before being re-enabled. You will need a high end scan tool (SnapOn scanner, Tech2 etc)

Read this thread as it should work on all VT's I think.

Note: If there is a fault in the circuit, lamp will go off and then come back on again a few seconds later.
If this is the case, of to someone with a proper scan tool to sort it out.
Common problem is the clockspring, which is what it was in mine.

I saw that thread previously, thanks for that.
I might give those commands a shot or use the adx file that was posted.
