<p>PURPOSE:To eliminate a trouble of not generating an alarm even in the changing period by easily deciding an error corrected of a detecting means by which the alarm is generated when an odometrical value difference, between a maintenance part change preset value of vehicle part and a preset value of an odometrical value memory means showing a travel distance, is a fixed value or more. CONSTITUTION:When a vehicle key is turned on, an error detecting part is started to operate, read a keyword of memory, decide a keyword error for whether provided or not (S1, 2), proceed to a process S6 in the case of no error, read a data from a non-volatile memory in the case of an error, and majority decision is performed (S3, S4) to record an odometrical value and T belt value in the memory (S5). The error detecting part decides an error for whether provided or not in these values (S6), proceed to a process S8 in the case of NO, return to the process S3 in the case of YES, and the processes S3 to S6 are repeated three times, to light an alarm lamp in the case of deciding the error. The odometrical value is subtracted from the T belt value of the memory, to decide a subtraction value for whether larger or not than a fixed value.</p> |
