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

        HINT: 

        If the ABS warning and slip indicator lights do not blink, inspect the TC and CG terminal circuit, and ABS warning and slip indicator light circuits.

        Trouble Area See procedure
        TC and CG terminal circuit Refer to TC and CG Terminal Circuit [08/2013 - 08/2015]
        ABS warning light circuit (Remains on) Refer to ABS Warning Light Remains ON [08/2013 - 08/2015]
        ABS warning light circuit (Does not come on) Refer to ABS Warning Light does not Come ON [08/2013 - 08/2015]
        Slip indicator light circuit (Remains on) Refer to Slip Indicator Light Remains ON [08/2013 - 08/2015]
        Slip indicator light circuit (Does not come on) Refer to Slip Indicator Light does not Come ON [08/2013 - 08/2015]
      5. 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, 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.
