*1: ”ON” displayed in the diagnosis mode column indicates that the check engine warning light is lighted
up when a malfunction is detected. ”OFF” indicates that the ”CHECK ENGINE” does not light up during mal-
function diagnosis, even if a malfunction is detected. ”N.A.” indicates that the item is not included in malfunc-
tion diagnosis.
*2: ”
f
” in the memory column indicates that a diagnostic trouble code is recorded in the ECU memory when
a malfunction occurs. ”X” indicates that a diagnostic trouble code is not recorded in the ECU memory even
if a malfunction occurs.
Accordingly, output of diagnostic results in normal or test mode is done with the IG switch ON.
