        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.

      6. Check the details of the DTCs.
