Can someone help me this 99 Chevrolet Silverado SRS module?
I think the crash is in the bottom left 8 pin eprom(the only 8 pin on the board). However, there are lotsa numbers on it:
1202405914
9834
16257785.
Which one is the chip number??
They are in same sequence on the eprom.
The part mumber of the module is: 16249007
Any help would be appreciated.

do i have to lift any pins because i hooked it up and it dont want to read it

[raddi]

UPA has perfect instructions on what pins to hook up and, if needed, which ones to lift.
