(4) 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 blinks, a 1.5 second pause, and then 1 blink).
- 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.
(5) Check the details of the DTCs.
