I have a 98 TJ and I have a code reader, but I've been too busy to dig it out, and its usually been the same code tripping every few days. I've been trying to do the ON-OFF-ON-OFF-ON thing with the key to check the codes, but it doesn't seem to work.
Is this something that only works on the newer TJs with the security key?
If not, do I have to go all the way back to locked-off or just unlocked-off?
Do I have to have the key in the on position for a certain amount of time before I switch it back to off for the next cycle?
