Title:
DEVICE FOR JUDGING FAULT DIAGNOSTIC FUNCTION
Document Type and Number:
Japanese Patent JP3918712
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a fault diagnostic function judging device capable of properly checking a function of a fault diagnostic device, a program and a recording medium.
SOLUTION: At Step 200, a completion/non-completion history of fault diagnosis of a sensor or the like is updated. That is, the data of completion/non-completion of the latest past 10 times are stored in the completion history areas 1-n. At Step 210, it is judged whether once or more fault diagnoses of the sensor or the like are completed in the past ten fault diagnoses. At Step 220, since the fault diagnosis is completed once or more in the past 10 times, it is determined that the fault diagnostic function is normal, and MIL6 is activated (for example, a light is turned off) to show the normality. On the other hand, at Step 230, since no fault diagnosis is completed in the past 10 times, it is determined that the fault diagnostic function is abnormal, and MIL6 is activated (for example, a light is turned on or flickered) to show the abnormality.
