2. Use of Blinking Warning Lamp for Diagnostic Code
• Using the diagnostic and memory clear switches, display diagnostic codes.
CAUTION
• Opening the memory clear switch followed by its reconnection will erase the stored diagnostic codes
from the memory. To avoid inadvertently erasing necessary codes, be sure to read well the procedure de-
scribed below before handling diagnostic codes.
2.1 Reading diagnostic codes
• To read a diagnostic code, observe how may times the warning
lamp flashes and how long each illumination lasts.
• The duration of illumination differs between the first and second
digits.
• Second digit: 1.2 sec.
• First digit: 0.4 sec.
• A diagnostic code consists of the flashing of second digit and the
flashing of first digit in that order. If a diagnostic code has “0” in
the second digit, only the first digit will be displayed.
• The same diagnostic code will be displayed 3 times in a row be-
fore moving to the display of the next code.
• After the last diagnostic code is displayed, the first code will be
displayed again 3 times in a row and then the subsequent
codes. This will be repeated.
2.2 Present diagnostic codes
• Turn the starter switch ON.
• Remove the diagnostic switch.
• Diagnostic codes will be displayed (flashing of the warning
lamp).
• When the diagnostic switch is connected, electronic control unit
will immediately stop (terminate) displaying diagnostic codes.
2.3 Present and past diagnostic codes
• Turn the starter switch to the ON position.
• Open the diagnostic switch.
• Open the memory clear switch.
• The corresponding warning lamp will display diagnostic codes
by flashing.
• Turn the starter switch to the OFF position, connect the memory
clear switch and then connect the diagnostic switch. The elec-
tronic control unit terminates (exits) the diagnostic code display-
ing mode.
