From my understanding on OBD I connectors I jump terminals A & B to bring up codes. The problem is that the only terminals that have wires are A(top right), M (just under A), and K (third to the left of M). Has someone removed terminals from the aldl? I can't find any loose wires. How can I pull codes to see why the SES light is on. When the van is first started it surges a little at idle and on acceleration. But after is runs for a minute warming up, then seems to run fine. I would appreciate any help possible. Thanks Ken
