Self-Diagnosis
Self-DiagnosisDESCRIPTION
During driving, the low tire pressure warning system receives the signal transmitted from the transmitter installed in each wheel, and turns on the low tire pressure warning lamp when the tire pressure becomes low.
The control unit (BCM) for this system has pressure judgement and self-diagnosis functions.
FUNCTION
When the low tire pressure warning system detects low inflation pressure or an internal malfunction, the low tire pressure warning lamp in the combination meter comes on. The malfunction location is indicated by the low tire pressure warning lamp flashing and the buzzer sounding.
