Display sample of diagnostic code
- The figure below (Fig. A) shows how the diagnostic codes, 21 and then 32 for example, are displayed.
- The interval of blinks of the lamp indicates the diagnostic codes. First, the lamp turns on for 0.5 second two times to indicate the "2" of the tens digit, and 1.5 seconds later, it turns on 1 times to indicate the "1" of the ones digit.
- To display the next code, which occurs 4.3 seconds later, it turns on 3 + 2 times in the same manner as the first code, and the display of these codes will be repeated thereafter.
- If the system operates properly without malfunctions, the lamp repeatedly turns on for 0.3 second. (Fig. B)
- The diagnostic codes for present malfunctions are repeatedly output in the order of smaller to larger codes.
