   3. Turn the ignition switch to ON.

   4. Observe the blinking pattern of the ABS warning and slip indicator lights in order to identify the DTC.

      Tip:

   5. Count the number of blinks of the ABS warning and slip indicator lights.

      Tip:

      • 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.
