Technical Service Bulletin
Technical Background
At certain outside temperatures and in certain operating conditions, the temperature in the passenger
compartment fluctuates. This fluctuation is caused by the unventilated sensor in the air conditioning control panel.

Production Solution
The sensitivity of the passenger compartment has been optimized. New software in the air conditioning/heating
control unit, J255 (and in the rear air conditioning/heating control unit, J265, if equipped) addresses the condition.
