DIAGNOSTIC TEST MODE II

In this mode, a diagnostic trouble code is indicated by the number of flashes from the RED LED or the MALFUNCTION INDICATOR LAMP 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 LED 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 mass air flow sensor. In this way, all the problems are classified by their diagnostic trouble code numbers.

The diagnostic results will remain in ECM memory.
