All the other lights turn on and off correctly with the key.

I rememberd one other thing. After replacing the battery, I checked the codes from pin 8 using the led/sw.

I did not insert the pins into the right sockets the first try.

Is it possible to damage the ECU by doing that?

I have misplaced Arther Dalton's schematic for the led/sw, so not sure what effect that would have.
