TROUBLE DIAGNOSIS
CONSULT-II Function
INFOID:0000000003532866
HOW TO CHANGE SELF-DIAGNOSIS MODE WITH CONSULT-II
From User Mode to Diagnosis Mode
After selecting “AIR BAG” on the “SELECT SYSTEM” screen, User mode automatically changes to Diagnosis
mode.
From Diagnosis Mode to User Mode
To return to User mode from Diagnosis mode, touch “BACK” key of CONSULT-II until “SELECT SYSTEM”
appears, Diagnosis mode automatically changes to User mode.
AIR BAG diagnostic mode Description
SELF-DIAG [CURRENT]A current Self-diagnosis result (also indicated by the number of warning lamp flashes in the Diagnosis
mode) is displayed on the CONSULT-II screen in real time. This refers to a malfunctioning part requiring
repairs.
SELF-DIAG [PAST]Diagnosis results previously stored in the memory are displayed on the CONSULT-II screen. The
stored results will remain until memory erasing is executed.
TROUBLE DIAG RECORDWith TROUBLE DIAG RECORD, diagnosis results previously erased by a reset operation can be dis-
played on the CONSULT-II screen.
ECU DISCRIMINATED NO.The air bag diagnosis sensor unit for each vehicle
model is assigned with its own, individual classifi-
cation number. This number will be displayed on
the CONSULT-II screen, as shown. When replac-
ing the air bag diagnosis sensor unit, refer to the
part number for the compatibility. After installation,
replacement with a correct unit can be checked by
confirming this classification number on the CON-
SULT-II screen.
The air bag diagnosis sensor unit discriminated
number assigned is F649.
PASSENGER AIR BAGThe STATUS (readiness) of the front passenger air
bag module is displayed. The STATUS displayed
(ON/OFF) depends on the signals supplied to the
occupant classification system control module and
air bag diagnosis sensor unit. Refer to SRS-6, "
Oc-
cupant Classification System (OCS)" for more in-
formation.

HOW TO ERASE SELF-DIAGNOSIS RESULTS
• “SELF-DIAG [CURRENT]”
A current self-diagnosis result is displayed on the CONSULT-II
screen in real time.
After the malfunction is repaired completely, no malfunction is
detected on “SELF-DIAG [CURRENT]”.
• “SELF-DIAG [PAST]”
Return to the “SELF-DIAG [CURRENT]” CONSULT-II screen by
touching “BACK” key of CONSULT-II and select “SELF-DIAG
[PAST]” in SELECT DIAG MODE. Touch “ERASE” in “SELF-DIAG
[PAST]” mode.
NOTE:
If the memory of the malfunction in “SELF-DIAG [PAST]” is
not erased, the User mode will continue to show the system
malfunction by the operation of the warning lamp even if the
malfunction is repaired completely.
• “TROUBLE DIAG RECORD”
The memory of “TROUBLE DIAG RECORD” cannot be erased.
Self-Diagnosis Function (Without CONSULT-II)INFOID:0000000003532867
• The reading of these results is accomplished using one of two modes — “User mode” and “Diagnosis
mode”.
• After a malfunction is repaired, turn the ignition switch OFF for at least one second, then back ON. Diagnosis
mode returns to the User mode. At that time, the self-diagnostic result is cleared.

1. If no DTC is detected on “SELF-DIAG [CURRENT]”, repair of
SRS is completed. Go to step 2.
If any DTC is detected on “SELF-DIAG [CURRENT]”, the mal-
functioning part has not been repaired completely or another
malfunctioning part is being detected. Go to "DIAGNOSTIC
PROCEDURE 2" .
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]”.
4. Check that no malfunction is detected on “SELF-DIAG [PAST]”.
5. Touch “BACK” key of CONSULT-II until “SELECT SYSTEM”
appears in order to return to User mode from Diagnosis mode.
6. Turn ignition switch OFF then turn off and disconnect CON-
SULT-II.
7. Go to SRS-20, "
SRS Operation Check" .
DIAGNOSTIC PROCEDURE 4
Check SRS Repair History
1.CONSIDER POSSIBILITY THAT SELF-DIAGNOSTIC RESULT WAS NOT ERASED AFTER REPAIR
Check repair history of the SRS.
Have any previous repairs been made to the SRS?
Yes >> Self-diagnostic result “SELF-DIAG [PAST]” (previously stored in the memory) might not be erased
after repair. Go to "DIAGNOSTIC PROCEDURE 3" .

LOW TIRE PRESSURE WARNING SYSTEM
LOW TIRE PRESSURE WARNING SYSTEM
System ComponentINFOID:0000000003532692
System DescriptionINFOID:0000000003532693
BODY CONTROL MODULE (BCM)
The BCM is shown with the lower instrument panel LH removed. The
BCM reads the air pressure signal received by the remote keyless
entry receiver, and controls the low tire pressure warning lamp as
shown below. It also has a self-diagnosis function to detect a system
malfunction.
TRANSMITTER
A sensor-transmitter integrated with a valve is installed in each
wheel, and transmits a detected air pressure signal in the form of a
radio wave. The radio signal is received by the remote keyless entry
receiver.

REMOTE KEYLESS ENTRY RECEIVER
The remote keyless entry receiver is shown with the instrument
panel RH removed. The remote keyless entry receiver receives the
air pressure signal transmitted by the transmitter in each wheel.
COMBINATION METER
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.
DISPLAY UNIT
Displays the air pressure of each tire.
• After the ignition switch is turned on, the pressure values will not
be displayed until the data of each wheel is received.
