DESCRIPTION
In this mode, a malfunction code is indicated by the number of
flashes from the RED L.E.D. or the E.C.M. LIGHT as shown below:
Long (0.6 second) blinking indicates the number of ten digits
and short (0.3 second) blinking indicates the number of single
digits.
For example, the red L.E.D. flashes once for 0.6 seconds and
then it flashes twice for 0.3 seconds. This indicates the number
"12" and refers to a malfunction in the air flow meter. In this
way, all the problems are classified by their code numbers.
