I just disconnected the battery for 1 hr. and no change.

Was thinking that maybe it would clear the light and SLS message only for it to return after a short time later. Nope, both conditions are still there immediately after connecting the battery.

Now trying to figure out a part number of the sensor without disassembling the console. I think I'll just have to do it so I'll search for a good thread on how best to remove the console.
