Note On Intermittents
WARNING: This page is about a different car, the 1990 Cadillac Seville and 1990 Cadillac Eldorado. However, it is still accessible from the selected car via links, so may be relevant.
If intermittent Code B115 is being set, manipulate related wiring while observing BCM parameter BD32. If failure is induced, reading will jump from its normal value to a reading outside range of -34°C to 96°C. If value displayed by BD32 is not reasonably close to actual thermometer reading, check for poor terminal connections or replace sensor.
