BCM (BODY CONTROL MODULE)
The BCM reads the air pressure signal received by the remote key-
less entry receiver, and controls the low tire pressure warning lamp
and the buzzer operations. It also has a judgement 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 and buzzer are activated.
Low Tire pressure Warning Lamp Indication
Note 1: Standard air pressure is for 220 kpa (2.2 kg/cm2 , 32 psi) vehicles.
DISPLAY UNIT
Displays the air pressure of each tire.

After the ignition switch is turned ON, the pressure values are
not displayed until the data of each wheel stabilizes.

TROUBLE DIAGNOSIS FOR SELF-DIAGNOSTIC ITEMS
Revision: 2006 December 2006 FX35/FX45
TROUBLE DIAGNOSIS FOR SELF-DIAGNOSTIC ITEMSPFP:00000
Inspection 1: Transmitter or Control Unit (BCM)NES000H1
MALFUNCTION CODE NO. 21, 22, 23 OR 24
1. CHECK CONTROL UNIT

Drive for several minutes. Check all tire pressures with CONSULT-II “DATA MONITOR ITEM”.
Are all tire pressures displayed 0 kPa?
YES >> GO TO 2.
NO >> GO TO 3.
2. CHECK REMOTE KEYLESS ENTRY RECEIVER CONNECTOR
1. Disconnect remote keyless entry receiver harness connector M98.
2. Check terminals for damage or loose connection.
3. Reconnect harness connector.
OK or NG
OK >> Replace BCM refer to BCS-15, "Removal and Installation of BCM" , then GO TO 3.
NG >> Repair or replace remote keyless entry receiver harness connector.
3. ID REGISTRATION

Perform ID registration of all transmitters.
Is there any tire that ID can not be registered to?
YES >> Replace transmitter of the tire, then GO TO 5.
NO >> GO TO 4.
4. VEHICLE DRIVING

Drive at a speed of 40 km/h (25 MPH) or more for several minutes without stopping.
Check all tire pressures with CONSULT-II “DATA MONITOR ITEM” within 15 minutes after vehicle speed
becomes 17 km/h (11 MPH).
Does
“DATA MONITOR ITEM” display tire pressure as normal without any warning lamp?
YES >> INSPECTION END
NO >> GO TO 5.
5. ID REGISTRATION AND VEHICLE DRIVING
1. Perform ID registration of all transmitters.
2. Drive at a speed of 40 km/h (25 MPH) or more for 3 minutes, and then drive the vehicle at any speed for 10 minutes. Then check all tire pressures with CONSULT-II “DATA MONITOR ITEM” within 5 minutes.
Does
“DATA MONITOR ITEM” display tire pressure as normal without any warning lamp?
YES >> INSPECTION END
NO >> GO TO the inspection applicable to DTC.
Inspection 2: Transmitter - 1NES000H2
MALFUNCTION CODE NO. 31, 32, 33, 34, 41, 42, 43, 44, 45, 46, 47 OR 48
1. ID REGISTRATION (CORRECTION OF TRANSMITTER LOCATION)
1. Perform ID registration of all transmitters.
2. Drive at a speed of 40 km/h (25 MPH) or more for 3 minutes, and then drive the vehicle at any speed for 10 minutes.
>> GO TO 2.
