When trying to run a start/run diagnostic test on my 91' "built" AOD coupe, the testing computer keeps indicating the car is in gear even when it is in park or neutral. Is there any possibility this could be happening b/c I have an A9L computer in the car versus an A9P? Does the A9L computer not pick up the neutral safety switch or something, therefore not allowing the diagnostic test?
I believe the car has always been an automatic but the computer that was in the car when I bought it was an A9L. The computer had some problems at one point in time so I just replaced it with another A9L, not knowing about the A9P computers at the time. Is this my problem or did some AOD cars come with A9L computers? Thanks for any input.
