DESCRIPTION

If the tire pressure warning ECU detects a malfunction, the tire pressure warning light blinks for 1 minute then stays on and tire pressure monitor is canceled at the same time. At this time, the ECU records a DTC in the memory.

Connecting terminals TC and CG of the DLC3 allows the tire pressure warning light to blink output DTCs.
