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.

Check the details of the DTCs.
