[gletom]

When I check the center for problems all the areas show problems.Low oil,water, refrigerant etc.The only problems I found was cruise.Is there a module that goes bad and will show everything is bad or low ? What Next? Thanks.

I ran into the same thing when I first bought my Reatta. There are two separate diagnostic systems built into the 1988-89 Reattas and there is some confusion about them.
