Title:
ELECTRONIC EQUIPMENT DEVICE
Document Type and Number:
Japanese Patent JP3772336
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To reduce development cost to realize a failure diagnostic function and to improve the accuracy of a failure diagnosis.
SOLUTION: A center module ECU 108 and an air-conditioning mechanism part are provided with room temperature sensors 151 and 152, and the module 108 outputs a sensor value detected by the sensor 151 to an air-conditioner ECU 121. And the module ECU 108 and the air-conditioner ECU 121 execute the same operation by using the sensor value. The air-conditioner ECU 121 sends the operation result to the module ECU 108, and the module ECU 108 compares those operation results and decides that a failure occurs in the air- conditioner ECU 121 or the air-conditioning mechanism part when each operation result does not coincide.
