Re: 92 jimmy ABS light on Service Engine light on
I've never heard of needing the vehicle's cigar lighter (not to be confused with a cigarette lighter) to read the codes. Auto Zone used to hand out a two pronged flat key to read power train codes that looked like the tool used to remove the cleats on golf shoes.
The jumpering method described by Chris works good. For power train codes jumper the two upper right pins with a paper clip then turn the ignition switch to the run position. Watch the Service Engine Soon light for trouble codes. It will start by flashing one long and two short flashes to indicate a "12" or start of file 3 times followed by any stored codes. At the end of any codes stored it will flash the 12 again to indicate end of file. For ABS codes use the same procedure but jumper the upper right to the second from left on the bottom. Code 14 seems to indicate the start and end of file on the ABS codes.
