System Diagnostic: Notes

Self-diagnostic function locates problems based on signals the keyless unit transmits to the CPU. Self-diagnostic function activates output devices. Output device operation is monitored to determine problem area by listening for the number of times the buzzer sounds. CPU determines the number of times the buzzer sounds according to the input situation. During output device operation check, keyless unit sends signal to CPU, and then CPU activates device every 3 seconds. To begin self-diagnostic function, perform the following procedure within 180 seconds. See BEGINNING SELF-DIAGNOSTIC FUNCTION.
