(1.1) Reading diagnosis codes
• To read a diagnosis 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 diagnosis code consists of the flashing of second digit and the
flashing of first digit in that order. If a diagnosis code has “0” in
the second digit, only the first digit will be displayed.
• The diagnosis code 01 will be displayed if the system is normal.
• The same diagnosis code will be displayed 3 times in a row be-
fore moving to the display of the next code.
• After the last diagnosis code is displayed, the first code will be
displayed again 3 times in a row and then the subsequent
codes. This will be repeated.
