GF82.20-P-4101-02N Overhead Control Panel Control Unit, Purpose

Measuring in-car temperature, purpose
The inside sensor blower in the overhead control panel control unit (N70) is actuated upon request of the automatic air conditioning control and operating unit via the CAN interior. First perform diagnosis on sensor blower.

Next, the overhead control panel control unit (N70) returns the status and the measured interior temperature to the automatic air conditioning control and operating unit via the CAN interior.

The automatic air conditioning control and operating unit also requests that the blower be turned on upon certain operating conditions even if the ignition is switched off (e.g., residual engine heat utilization).
