Answer
Ah, sorry I do apologize,
but my expertise is in after
market vehicle alarm systems.

If yours is indeed a factory system,
I suggest talking to one of the
techs in my Forum about this one.

I am certain my guys will be
happy to assist if possible.

I hope you find the answer/solution
to your issue.
