      Tech Tips

      
      

      • How to read DTCs:

        Diagnostic trouble codes are represented by the number of blinks of a warning light. For example, code 21 would be shown by 2 blinks, a pause of 1.5 seconds, and then 1 blink.

      • If one code is detected:

        The light repeats the same code after a pause of 4 seconds.

      • If multiple codes are detected:

        The light outputs one code after another with a 2.5-second pause between each code.

        When all codes have been output, there is a 4-second pause and then the light begins to output the codes again.

      • If more than 1 malfunction is detected at the same time, the lowest numbered code will be displayed first.

   6. Check the details of the DTCs.
