AMBIENT TEMPERATURE DISPLAYS 220

On Avalon models equipped with an ambient temperature display, 22°F may appear in the ambient temperature display if continuity through the ambient temperature sensor circuit is interrupted. Since the 22°F is retained in memory, the condition will persist even after continuity through the ambient temperature sensor circuit has been re-established. Climate control system operation may also be adversely affected.

This condition can be corrected by briefly removing the fuse supplying the B+ power source to the A/C amplifier.

Do not attempt repairs before performing the following reset procedure:

RESET PROCEDURE:








Remove the following fuse for 30 seconds and reinstall (see illustration):

If ambient temperature display is not corrected, refer to repair manual for diagnosis.
