      3. Turn the ignition switch to ON.

      4. Observe the blinking pattern of the ABS warning, tire pressure warning (w/ tire pressure warning system) and slip indicator lights in order to identify the DTC.

        Tip:

        If ABS warning, tire pressure warning (w/ tire pressure warning system) and slip indicator lights do not blink, inspect the TC and CG terminal circuit, ABS warning and slip indicator light circuits and tire pressure warning system (w/ tire pressure warning system).

      5. Count the number of blinks of the ABS warning, tire pressure warning (w/ tire pressure warning system) 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.

        *1: This DTC is stored when the VSC system detects a malfunction in the ABS.

        *2: The light blinks 6 times, turns off for 1.5 seconds, and then blinks 10 times.

        *3: If no DTCs related to the tire pressure warning system (w/ tire pressure warning system) are detected, the tire pressure warning light blinks 4 times, turns off for 1.5 seconds, and then blinks 7 times, repeatedly.

      7. After completing the check, disconnect terminals TC and CG of the DLC3 to turn off the display.

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

    2. Clear the DTCs.

      1. Turn the ignition switch off.

      3. Turn the ignition switch to ON.

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

      5. Check that the ABS warning, tire pressure warning (w/ tire pressure warning system) and slip indicator lights indicate the normal system code.

      6. Remove SST from the terminals of the DLC3.

        Tip:

        The DTCs cannot be cleared by disconnecting the battery terminal or the IG1 NO. 1 fuse.

  3. END OF DTC CHECK/CLEAR

    1. Turn the ignition switch to ON.

    2. Check that the ABS warning, tire pressure warning (w/ tire pressure warning system) and slip indicator lights go off within approximately 3 seconds of turning the ignition switch to ON.

      Tip:

      • During the tire pressure warning system initialization: The tire pressure warning light illuminates for 4 seconds.

      • After the tire pressure warning system initialization: The tire pressure warning light illuminates for 3 seconds.
