• How to erase the self-diagnostic fault code from memory:
If the ECU detects a normal signal upon the completion of the repair of the malfunction, the self-
diagnostic fault code disappears from the meter and is replaced by the normal clock display. How-
ever, the self-diagnostic fault code of the previous malfunction remains in the ECU memory as
part of the malfunction history. To erase the self-diagnostic fault code from the malfunction history,
the operation for diagnostic code 62 must be performed in the diagnosis mode.
