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.

Tire pressure receiver

Receives radio wave signals converted from tire pressure signals.

Tire pressure warning check switch

Allows a mode to be switched to a diagnosis mode.

Turn signal lamp

ID registration of each wheel has been completed, turn signal lamp flashes.

Combination meter

Controls a low tire pressure warning lamp, turn signal lamp, and buzzer by signals from the 
unified meter and A/C amp.

Low tire pressure warning lamp

Illuminates if malfunction is detected in electrical system of TPMS.

Unified meter and A/C amp.

Transmits the vehicle speed signal via CAN communication to BCM.
Receives the tire pressure signal via CAN communication to BCM.

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

to 

WT-74, "DTC Index"

.

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.
