View Full Version : 93 Brougham Question

04-12-05, 05:30 PM
I have a 93 Brougham and was wondering how to get into the OBD diags. I'm sure it's done through the climate control but I can't figure it out. I'd like info on entering diag, navigating the system and clearing codes.

Temp incraease (warmer) and off buttons simultaneously. Hold and wait for the "everything" flash. You'll be at pointer 00 PCM. 01 is for ECM, 02 is for Climate control, etc.

You need the servicve manual for all the various codes in each pointer.

OK so then I can scroll from -32 to 32 but what does that give me? I can't seem to get any codes or diag info. I know in the 89 STS I can read live data from the ECM, BCM and so on. Can I do that here?
