Note On INTERMITTENTS:
WARNING: This page is about a different car, the 1986 Oldsmobile Toronado and 1986 Buick Riviera. However, it is still accessible from the selected car via links, so may be relevant.
If an intermittent Code B409 is being set, manipulate circuit 25. When BCM input BI51 change-of-state indicator displays an "X", the failure has been induced.
