SELF-DIAGNOSTIC SYSTEM DESCRIPTION
The self-diagnostic system determines malfunctions of signal systems such as sensors, actuators, and wire harnesses based on the status of the input signals received by the ECC control unit. A malfunction is displayed by both the Red and Green LEDs (Light Emitting Diodes).
Basically, self-diagnosis is always performed when the power is furnished to the ECC control unit. The self-diagnosis results are retained in the memory chip of the ECC control unit and are displayed only when the diagnosis mode selector (located on the side of the control unit) is turned to "ON".
The self-diagnosis system is provided with functions which display malfunctions being checked as well as those which are stored in memory. In this sense, it is very effective in determining an "intermittent" malfunction. The results which are or were stored in the memory can be erased by following steps specified.
A malfunctioning area is determined by the number of flashes of both the Red and Green LEDs. First, the Red LED flashes and the
Green follows. The Red LED refers to the tenth digit while the Green one refers to the unit digit. For example, when the Red LED flashes three times and the Green LED flashes twice, this implies number "32". In this way, all problems are classified by code numbers.
