Here's how to check a '91-'94 Bravada for trouble codes:
Jumper the 2 top right hand holes on the assembly line diagnostic link(ALDL)under the steering column-lower dash area then turn on the ignition switch and count the check engine light flashes. You'll get a single then double flash...1-2 or code 12 three times which means the computer is saying "Ok Pal, I'm gonna tell ya any trouble codes stored". Any codes stored will flash 3 times.After all the codes stored are shown you'll get another set of code 12's which let's you know "that's all folks" unless you want to see again which it'll then just keep reporting the stored codes. When you get through, just cut the ignition switch off and pull your jumper wires. To reset the check engine light, disconnect either battery cable for 15 to 20 seconds.Let us know what codes are stored and we'll discuss what's the problem.
