no guages & check engine light 02 malibu

[cardot33]

So I've been driving around this 2002 Malibu 3.1 V6 and one day I got a check engine light. so I thought, alright, I'll check the codes like I did in the 89 camaro. BAD IDEA! terminals A and B didn't have anything in them, so no diagnostic mode. being the idiot that I can be I proceded to crossing pretty much any combination of terminal I could. I never found diagnostic mode, and immediately after and since, my guages haven't been working. The car drives normally, I bet I blew a fuse, but they all look fine. What can I do to get my guages back?

OBD2 and OBD1.5 don't have the diagnostic capability of jumping the pins in the ALDL/ALCL port.

as far as the guages, i would check all of your fuses, since those ports are never meant to have anything in them other than a scanner/code reader.

go to any autozone and they'll scan codes for free.

any idea which fuse box to check because I've pretty much checked them all and haven't found a bad one yet.
how's your monte carlo doing robertisaar? I remember seeing that damage in your signature a while ago.

still damaged.... waiting on the cash for new a new fender/door.

i'll check what i can through alldata and edit this post.

EDIT: i'm going to guess that either the BCM could be causing this, or something got burnt out when you were trying to pull diagnostic codes. the pins in the connector are 2 grounds, +12Volts and then class 2 serial data.

i'm seeing fuses for the BCM in the left-hand instrument panel fuse block and the underhood fuse block. nothing in the right-side.

does anything light up in the dash? not even backlights?
