So I decided I'd get around to checking my annoying CEL to see exactly what it is. I know I've got a cracked exh manifold but I'd like to know what the code is. The book is confusing saying to use a analog volt meter on the DLC by the fuse box and read it kinda like the older cars where you ground 2 pins and it flashes codes with the light. Can it do that? Or do you need to use the DLC? Would a test light do the same thing since I cant remember the last time I used an analog volt meter and my digital one isn't going to pick up swings in voltage like that even tho it's a step under a fluke meter.
