'96 Chevy C1500, Trouble Codes
Q:
Hi,
I have a '96 Chevy C1500 with a 4.3l engine. I was wondering if there
is a way for me to pull the codes thru the connector? I have heard that
you can jump 2 of the plugs but I wasn't sure which ones or if that was
true. If you could let me know that would be great!

Once
upon a time you could use a jumper to get the vehicle's computer to blink/flash
the check engine light to retrieve diagnostic trouble codes. Well, you
just can't do that any more. You will need some sort of code reader or
scan-tool to get that information from your vehicle's computer. About
the only thing you can do with the new diagnostic systems connectors is
blow fuses, damage system components, retrieve anti-lock brake diagnostic
codes (warning only on some systems) and in general cause more trouble
for yourself than you can image.
