Hi,

Hum? I’m not a 900 man so I used the web site referenced.
From the web site provided it shows a flashing light down on the shifter. Is this the light you are referring too?
Check engine codes on the 240s are emissions codes in 1992. On those it’s a diagnostic box that blinks.
It looks like the shifter one warns the driver that the transmission is in a Winter mode that uses only upper gear range to reduce slipping the wheels loose.
The six cylinders do make a lot more torque at very low RPMs. They gotta get something more for two more pistons to go up and down. (:)

Is the transmission doing anything weird or do you like working on puzzles because their there?
I tinker, to just tinker, but a Sudoku game, every once in awhile. It’s a tantalizer that gets me!

A missing signal could be a corrupted signal from a corroded connection.
Signal shapes are compared to base signals in electronics.
Just a thought!
