2. The part number described on low tire pressure warning control unit sticker is displayed.
Diagnosis Procedure with Warning Lamp Function (Without CONSULT-II)NES000K6
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 (low tire pres-
sure warning control unit) of 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 lamps in the combination meter comes on. To start the self-diagnostic results mode, ground terminal
of the tire pressure warning check connector. The malfunction location is indicated by the warning lamp flash-
ing and the buzzer sounds. Regarding location of tire pressure warning check connector, refer to PG-63,
"HARNESS" .
