      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.

        HINT: 

        If no code is output, inspect the TC and CG terminal circuit and ABS warning light and slip indicator light circuits.

        Trouble Area See Procedure
        TC and CG terminal circuit Refer to TC and CG Terminal Circuit
        ABS warning light circuit (Remains on) Refer to ABS Warning Light Remains ON
        ABS warning light circuit (Does not come on) Refer to ABS Warning Light does not Come ON
        Slip indicator light circuit (Remains on) Refer to Slip Indicator Light Remains ON
        Slip indicator light circuit (Does not come on) Refer to Slip Indicator Light does not Come ON
      5. Count the number of blinks of the ABS warning and slip indicator lights.

        HINT: 

        • When the system is operating correctly, each light will blink continuously in a pattern of 0.25 seconds on, and then 0.25 seconds off.
        • When one DTC is output, each light will output the same code at 4 second intervals (for example, code 21 would be output as 2 flashes, a 1.5-second pause, and then 1 flash).
        • When 2 or more DTCs are output, each light will output a different code at 2.5-second intervals, and when all codes have been output, there will be a 4-second pause and the sequence will repeat.
        • When multiple codes are stored, they are output in order starting with the lowest DTC number.
      6. The codes are explained in the code table.

      7. After completing the check, disconnect terminals 13 (TC) and 4 (CG) of the DLC3 to turn off the display.

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

    2. Clear the DTCs.
      1. Turn the ignition switch off.
      2. Using SST, connect terminals 13 (TC) and 4 (CG) of the DLC3.
