Judgement Self-diagnosis Code
If there is a malfunction, the lamp lights up for the time corresponding to the suspect circuit.
Erase Self-diagnosis

In order to make it easier to find the cause of hard-to-duplicate malfunctions, malfunction information is
stored into the control unit as necessary during use by the user. This memory is not erased no matter how
many times the ignition switch is turned ON and OFF.

However, this information is erased by turning ignition switch OFF after performing self-diagnostics or by
erasing the memory using the CONSULT-II.
