DIAGNOSTIC PROCEDURE 3
Final inspection after repairing SRS by using CONSULT-II — Diagnosis mode
Refer to GI-38, "
CONSULT-II Start Procedure" .
CAUTION:
If CONSULT-II is used with no connection of CONSULT-II CONVERTER, malfunctions might be
detected in self-diagnosis depending on control unit which carry out CAN communication.
1. Touch “SELF-DIAG [CURRENT]”.
a. If no malfunction is detected on “SELF-DIAG [CURRENT]”, repair of SRS is completed. Go to step 2.
b. If any malfunction is detected on “SELF-DIAG [CURRENT]”, the malfunctioning part is not repaired completely or another mal-
functioning part is detected. Go to SRS-22, "
DIAGNOSTIC
PROCEDURE 2" , and repair malfunctioning part completely.
2. Touch “ERASE”. NOTE:
Touch “ERASE” to clear the memory of the malfunction (“SELF-
DIAG [PAST]”).
If the memory of the malfunction in “SELF-DIAG [PAST]” is not
erased, the User mode shows the system malfunction by the
operation of the warning lamp even if the malfunction is repaired
completely.
3. Touch “BACK” key of CONSULT-II to “SELECT DIAG MODE” screen. Touch “SELF-DIAG [PAST]”.

3. Touch “TROUBLE DIAG RECORD”.
NOTE:
With “TROUBLE DIAG RECORD”, diagnosis results previously
erased by a reset operation can be displayed.
4. Diagnostic code is displayed on “TROUBLE DIAG RECORD”.
5. Touch “PRINT”.
6. Compare diagnostic codes to SRS-30, "
DTC No. Index (“SELF-
DIAG [PAST]” or “TROUBLE DIAG RECORD”)" .
7. Touch “BACK” key of CONSULT-II until “SELECT SYSTEM” appears.
8. Turn ignition switch OFF, then turn off and disconnect CON- SULT-II, and both battery cables.
9. Repair the system as outlined by the “Repair order” in “Intermit- tent Malfunction Diagnostic Code Chart”, that corresponds to the
self-diagnostic result. For replacement procedure of component
parts, refer to the Removal and Installation procedure for the appropriate component.
10. Go to SRS-27, "
DIAGNOSTIC PROCEDURE 3" , for final inspection.

TIRE PRESSURE MONITORING SYSTEMPFP:40720
System ComponentsNES000GP
System DescriptionNES000GQ
TRANSMITTER
A sensor-transmitter integrated with a valve is installed on a wheel,
and transmits a detected air pressure signal in the form of a radio
wave.
REMOTE KEYLESS ENTRY RECEIVER
The remote keyless entry receiver receives the air pressure signal
transmitted by the transmitter in each wheel.

TIRE PRESSURE MONITORING SYSTEM
Revision: 2006 July 2007 FX35/FX45
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 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 1: Standard air pressure is for 220 kpa (2.2 kg/cm2 , 32 psi) vehicles.
RUN-FLAT TIRE 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 run-frat tire warning
lamp and buzzer are activated.
