SELF-DIAGNOSIS FUNCTION
The self-diagnosis function is incorporated in the ECM. The function has two modes, User mode and
Dealer mode. The user can only be notified by the LCD (DISPLAY) panel and LED (FI light). To check the
function of the individual FI system devices, the dealer mode is prepared. In this check, the special tool is
necessary to read the code of the malfunction items.
