please help asap
hello guys and gals , new to the board and in need of some help
1. I own a 1998 GMC jimmy 4x4 sle, 4dr
bought if from my parents so I could store my summer ride during the winter, last week before work I started it up and seen that no gauges worked for about 10 sec then all was fine, started to drive it and it would not shift out of second , called a pal and he tells me to unhook the battery for a hr to reset the ecm, he said it went into a reduced power mode, he came over a few days later to scan the codes, had an LF wheel speed sensor open (knew that) the other codes were gone do dis-connect of battery, last night @ 11pm in the rain the jimmy did the same thing , hence dis connect battery for hr. and drove the beast home what is causing the mystery problem, I dont have a tech 2 to scan the codes and the dudes at auto zone couldn't butter bread let alone tell me what code it is ?? thanks in advance

no just the service engine, and my ABS (which I know about)
my friend is saying it might be a corroded wire behind the right kick pad, note the jimmy has 196 k on it

Gotta pull the DTC's and post them. I agree with Diaita on the possibility of a faulty ignition switch. This link will help in diagnosis: https://blazerforum.com/forum/articl...-switch-33465/
Disconnecting the battery, for any length of time, will not "reset" or clear any DTC's from the memory files, (pending, current & history) basically it's a waste of time. It will turn the SES light off only if there are no current hard faults present.

Did you diagnose the ignition switch as being bad, or are you guessing/hoping?
