(d) Read and record any DTCs from the tire pressure warning light in the combination meter.

HINT:

When only 1 DTC is stored, the light outputs the same code after an interval of 4.5 seconds. Example: When DTC 21 is stored, the light blinks twice, turns off for 1.5 seconds, blinks once, turns off for 4.5 seconds, and then repeats this output pattern.
When 2 or more DTCs are stored, the light outputs the codes with an interval of 2.5 seconds between each different code and the output of all codes repeats after an interval of 4.5 seconds.
If the tire pressure warning light does not output any DTCs or the tire pressure warning light turns on and goes off repeatedly at 0.25 second intervals, inspect the tire pressure warning light circuit or TC and CG terminal circuit.
