DIAGNOSIS SYSTEM (AIRBAG)

Diagnosis Description

INFOID:0000000003367576

CAUTION:

• Do not use electrical test equipment on any circuit related to the SRS unless instructed in this Ser-

vice Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or harness
connectors.

• Do not repair, splice or modify the SRS wiring harness. If the harness is damaged, replace it with a

new one.

• Keep ground portion clean.

DIAGNOSIS FUNCTION

• The SRS self-diagnosis results can be read by using air bag warning lamp and/or CONSULT-III.
• The user mode is exclusively prepared for the customer (driver). This mode warns the driver of a system

malfunction through the operation of the air bag warning lamp.

• The diagnosis mode allows the technician to locate and inspect the malfunctioning part.
• The mode applications for the air bag warning lamp and CONSULT-III are as follows.

HOW TO PERFORM TROUBLE DIAGNOSIS FOR QUICK AND ACCURATE REPAIR

A good understanding of the malfunction conditions can make troubleshooting faster and more accurate.
In general, each customer feels differently about a malfunction. It is important to fully understand the symp-
toms or conditions for a customer complaint.

Information from Customer.

• WHAT..... Vehicle model.
• WHEN..... Date, Frequencies.
• WHERE..... Road conditions.
• HOW..... Operating conditions, Symptoms.

Preliminary Check.

Check that the following parts are in good order.
• Battery (Refer to 

PG-3, "How to Handle Battery"

).

• Fuse (Refer to 

PG-79, "Fuse"

).

• System component-to-harness connections.

HOW TO ERASE SELF-DIAGNOSTIC RESULTS (With CONSULT-III)

• “SELF-DIAG [CURRENT]”

A current self-diagnosis result is displayed on CONSULT-III screen in real time.
After the malfunction is repaired completely, no malfunction is detected on “SELF-DIAG [CURRENT]”.

• “SELF-DIAG [PAST]”

Return to “SELF-DIAG [CURRENT]” CONSULT-III screen by touching “BACK” key of CONSULT-III and
select “SELF-DIAG [CURRENT]” in SELECT DIAG MODE. Touch “ERASE” in “SELF-DIAG [CURRENT]”
mode.
NOTE:
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.

• “TROUBLE DIAG RECORD”

The memory of “TROUBLE DIAG RECORD” cannot be erased.

HOW TO ERASE SELF-DIAGNOSTIC RESULTS (Without CONSULT-III)

After a malfunction is repaired, turn the ignition switch OFF for at least one second, then turn ignition switch
ON diagnosis mode returns to the user mode. At that time the self-diagnosis result is cleared.

DIAGNOSTIC PROCEDURE (With CONSULT-III)

CONSULT-III Function

INFOID:0000000003367577

DIAGNOSIS MODE FOR CONSULT-III

• “SELF-DIAG [CURRENT]”

A current self-diagnosis results (also indicated with the number of warning lamp blinks in diagnosis mode)
are displayed on CONSULT-III 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 CONSULT-III screen. The stored results
are not erased until memory erasing is executed.

• “TROUBLE DIAG RECORD”

With TROUBLE DIAG RECORD, diagnosis results previously erased by a reset operation can be displayed
on CONSULT-III screen.

• “DISCRIMINATED NO.”

The air bag diagnosis sensor unit for each vehicle model has its own individual classification number. This
number will be displayed on CONSULT-III screen, as shown. When replacing 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 CONSULT-III screen.
After repair, check that the discriminated number of air bag diagnosis sensor unit installed to vehicle are the
same. Refer to 

SR-41, "Removal and Installation"

.

 HOW TO CHANGE SELF-DIAGNOSIS MODE WITH CONSULT-III

From User Mode to Diagnosis Mode

After selecting “AIR BAG” on the “SELECT SYSTEM” screen, User mode automatically changes to Diagnosis
mode.

DTC B1033, B1034 [UNIT FAIL] CRASH ZONE SENSOR

Main “G” sensor generates signal voltage, when it detects deceleration beyond the specified level caused by
vehicle frontal collision.

OPERATION

When air bag diagnosis sensor unit define the both signal voltage of the “G” sensor and the safing algorithm to
be that of collision which exceeds specified level, the driving circuit switches on and feeds the electric ignitor of
both driver and passenger air bags and pre-tensioner seat belt.

STRUCTURE

Integrated type of the “G” sensor element for frontal collision with output terminals for signal voltage.

INSTALLATION

Crash zone sensor is installed on the radiator core support assembly with fixed nuts.

Is the inspection result normal?

YES

>> GO TO 3.

NO

>> Repair or replace wiring harness.

3.

CHECK CRASH ZONE SENSOR

1.

Description

INFOID:0000000003367593

DTC B1035, B1036, B1038, B1040 [COMM FAIL] CRASH ZONE SENSOR

Main “G” sensor that generates signal voltage, when it detects deceleration beyond the specified level caused
by vehicle frontal collision.

OPERATION

When air bag diagnosis sensor unit defines both signal voltage of the “G” sensor and the safing algorithm to
be that of collision which exceeds specified level, the driving circuit switches on and feeds the electric ignitor of
both driver and passenger  air bags and pre-tensioner seat belt.

STRUCTURE

Integrated type of the “G” sensor element for frontal collision with output terminals for signal voltage.

INSTALLATION

Crash zone sensor is installed on the radiator core support assembly with fixed nuts.
