HINT
* When the system is operating correctly, the light will blink continuously in a pattern of 0.25 seconds on, and then 0.25 seconds off.
* When one DTC is output, the 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, the light will output each 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.
* If the tire pressure warning light does not indicate any DTCs or the normal system code, inspect the tire pressure warning light circuit or TC and CG terminal circuit.
