        • SST: 09843-18040 
      2. Turn the engine switch on (IG).
      3. Observe the blinking pattern of the ABS warning and SLIP indicator lights in order to identify the DTC.

        HINT: 

        If no code appears, inspect the TC and CG terminal circuit, and ABS warning and SLIP indicator lights circuits.

        Trouble Area See procedure
        TC and CG terminal circuit Refer to TC and CG Terminal Circuit
        ABS warning light circuit Refer to ABS Warning Light Remains ON or ABS Warning Light does not Come ON
        SLIP indicator light circuit Refer to Slip Indicator Light Remains ON or Slip Indicator Light does not Come ON
      4. Count the number of blinks of the ABS warning and SLIP indicator lights.

        HINT: 

        • How to read DTCs:

          Diagnostic trouble codes are represented by the number of blinks of a warning light. For example, code21 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. Codes are explained in the code table. Refer to DIAGNOSTIC TROUBLE CODE TABLE .
      6. After completing the check, disconnect terminals TC and CG of the DLC3, and 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 DTC.
      1. Using SST, connect terminals TC and CG of the DLC3.

      4. Check that the warning light indicates a normal system code.
      5. Remove the SST from the terminals of the DLC3.
