Iv'e been trying to read the codes on my 94 wrangler and i have searched all the threads but could not find an answer for a single flash that i assume means just a 1. I did read where someone else had the same code and was told to confirm the single flash but he never replied. I've checked mine several times and it it a single flash. My jeep has a diognostic plug near the master cylinder but a mechanic told me that it had no power to it and left it at that. still having a hard time finding my way around in the forum but bear with me i'm 68 and we were still using stone tablets and chisles when I went to school. Any help would be appreciated. Thanks!!
