Note On Intermittents

A BCM Code F10 will be stored in memory whenever the ambient temperature drops to less than -29°F (-34°C). This code should be ignored if this cause is suspected.

If intermittent Code F10 is being set, manipulate related wiring while observing BCM data parameter P.2.6. If failure is induced, reading will jump from its normal value to a reading outside range of -29°F to 189°F (-34°C to 87°C).

If value displayed by parameter P.2.6 is not reasonably close to actual temperature of air at sensor, check for poor terminal contact or replace sensor. The temperature of air at sensor can be influenced by a hot radiator, if sufficient air is not passing by sensor.
