DTC output mode is set by connecting terminals 13 (TC) and 4 (CG) of the DLC3. The DTCs are indicated by the tire pressure warning light blinking pattern.
If the ECU detects trouble, the tire pressure warning light blinks (illuminates after blinking for 1 minute) and tire pressure monitoring is canceled at the same time. At this time, the ECU stores a DTC in the memory.
Connect terminals TC and CG of the DLC3 to make the tire pressure warning light blink and output the DTC.
