Many cars and trucks can have security problems but most will set a code when this happens. some of the comon problemns would be a bad ignition switch, this problem normally sets many codes. Bad fuel pumps are another comon fault, has anyone scan it for cosdes? and if so what codes are set?
My mechanic tells me this a.m. that it is the security system that's causing the problem. He is working on resetting the security system but isn't having any luck. I also looked up the TSBs for my car's yr/make/model but there isn't anything about this particular problem. Any idea how to reset or reprogram the security system of an '02 Blazer?
Since this has been a problem that comes and goes I dont think a relearn is a perminet fix. The system needs to be diagnoised as to why this keeps happening. Has he found any codes?
