Self-DiagnosisEES001I9
DESCRIPTION
During driving, the low tire pressure warning system receives the signal transmitted from the transmitter
installed in each wheel, and gives alarms when the tire pressure becomes low. The control unit (BCM) for this
system has pressure judgement and trouble diagnosis functions.
FUNCTION
When the low tire pressure warning system detects low inflation pressure or another unusual symptom, the
warning lamp in the combination meter comes on. To start the self-diagnostic results mode, ground the tire
pressure warning check terminal. The malfunction location is indicated by the warning lamp flashing and the
buzzer sounds.
