Infiniti G35 (V35) Sedan. Manual — part 1455
WT-8
< FUNCTION DIAGNOSIS >
TPMS
The BCM (1) reads the air pressure signal received by the tire pres-
sure receiver, and controls the low tire pressure warning lamp and
the buzzer operations. It also has a judgment function to detect a
system malfunction.
LOW TIRE PRESSURE WARNING LAMP
The combination meter receives tire pressure status from the BCM
using CAN communication. When a low tire pressure condition is
sensed by the BCM, the combination meter low tire pressure warn-
ing lamp is activated.
Low tire pressure warning lamp indication
NOTE: Standard air pressure is for 230 kPa (2.3 kg/cm
2
, 33 psi) vehicles.
TIRE PRESSURE WARNING CHECK SWITCH
The following item can be checked by grounding the tire pressure
warning check switch (1) harness connector terminal.
• The low tire pressure warning lamp in the combination meter will
flicker according to the self-diagnostic results.

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 warning lamps in the combi-
nation meter comes on.
SELF DIAGNOSTIC PROCEDURE (WITH CONSULT-III)
With CONSULT-III
• Touch “SELF-DIAG RESULT” display shows malfunction experienced since the last erasing operation. Refer
SELF DIAGNOSTIC PROCEDURE (WITHOUT CONSULT-III)
Without CONSULT-III
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 flashing.
NOTE:
When the low tire warning lamp flashes 5 Hz and continues repeating it, the system is normal.
