TROUBLE DIAGNOSIS
Revision: 2006 November2007 350Z
Diagnosis Procedure with Warning Lamp Function (Without CONSULT-III)NES000A4
DESCRIPTION
During driving, the low tire pressure warning system receives the signal transmitted from the transmitter
installed in each wheel. The control unit (BCM) 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. Refer to PG-41, "
HARNESS" .
