      2. Turn the power switch on (IG).

      3. Observe the blinking pattern of the ABS warning, brake warning / yellow (minor malfunction) and slip indicator lights in order to identify the DTCs.

        Tech Tips

        If the ABS warning, brake warning / yellow (minor malfunction) and slip indicator lights do not blink, inspect the TC and CG terminal circuit, and ABS warning, brake warning / yellow (minor malfunction) and slip indicator light circuits.

      4. Count the number of blinks of the ABS warning, brake warning / yellow (minor malfunction) and slip indicator lights.

        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.

      5. Check the details of the DTCs.

      6. After completing the check, disconnect terminals TC and CG of the DLC3 to stop displaying DTCs.

        If 2 or more DTCs are detected at the same time, the DTCs will be displayed in ascending order.

    2. Clear the DTCs.

      2. Turn the power switch on (IG).

      3. Clear the DTCs stored in the ECU by depressing the brake pedal 8 times or more within 5 seconds.

      4. Check that the ABS warning, brake warning / yellow (minor malfunction) and slip indicator lights indicate the normal system code.

      5. Remove SST from the terminals of the DLC3.

        Tech Tips

        The DTCs cannot be cleared by disconnecting the auxiliary battery terminal or the IG1 NO. 2 fuse.

  3. END OF DTC CHECK/CLEAR


    1. Turn the power switch on (IG).

    2. Check that the ABS warning, brake warning / yellow (minor malfunction) and slip indicator lights go off when the power switch is turned on (READY).
