Title:
DIAGNOSING SYSTEM FOR VEHICLE
Document Type and Number:
Japanese Patent JP3203884
Kind Code:
B2
Abstract:
PURPOSE: To surely judge whether the anomaly information is the one before deletion or after deletion by installing an anomaly information transmission means which transmits the anomaly information after deletion during the deletion of the anomaly information by an anomaly information deletion means to a diagnosing device.
CONSTITUTION: A controller 100 receives the signals supplied from a sensor for detecting a various states of a vehicle and outputs each control signal to a variety of actuators for controlling the vehicle on the basis of the sensor signal. The CPU 110 of the controller 100 performs processing for the code deletion demand supplied from a diagnosing device 200. The existence of the code detetion demand supplied from the diagnosing device 200 during the time from the preceding start to the start at this time is detected. In case of the code deletion execution when code read-out is demanded, an anomaly code is searched from a SRAM, and the data (anomaly code does not exist) after the code deletion is transmitted to a diagnosing device without transmitting the result to the diagnosing device. Accordingly, in case of the code deletion execution in the case when read-out is demanded, the transmission of the data before deletion to the diagnosing device can be prevented.
