    2. Turn the ignition switch to ON.

    3. Count the number of blinks of the ABS warning light.

      HINT:
      1. When the system is operating correctly, each light will blink continuously in a pattern of 0.25 seconds on, then 0.25 seconds off.
      2. 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)
      3. 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.
      4. When multiple codes are set, they are output in order starting with the lowest DTC number.
      5. If no code is output, inspect the 13 (TC) and 4 (CG) terminal circuit and the ABS warning light circuits.
