Description

INFOID:0000000001686991

During driving, the TPMS receives the signal transmitted from the transmitter installed in each wheel, when
the tire pressure becomes low. The control unit (BCM) of this system has pressure judgment and trouble diag-
nosis functions.
When the TPMS detects low inflation pressure or another unusual symptom, the low tire pressure warning
lamps in the combination meter comes on.
