4. Disconnect diagnosis sensor unit (1) harness connectors (A).
5. Remove harness clip (B).
6. Remove fixing bolts (C), and then remove diagnosis sensor unit.
CAUTION:
 Never impact the diagnosis sensor unit.
 Replace the diagnosis sensor unit if it has been dropped or
sustained an impact.
 Replace the diagnosis sensor unit of deployed SRS air bag and deployed SRS front seat belt pre-ten-
sioner.
INSTALLATION
Install in the reverse order of removal.
CAUTION:
 Never use old fixing bolts after removal; replace with new fixing bolts.
 In the case that a malfunction is detected by the air bag warning lamp, after repair or replacement of
the malfunctioning parts, reset the memory by self-diagnosis or by CONSULT-III.
 After the work is completed, check that no system malfunction is detected by air bag warning lamp.
Refer to SRC-10, "
Diagnosis Description".
ECU DISCRIMINATED NO.
After replacing the diagnosis sensor unit, confirm that the diagnosis sensor unit identification is correct for the
vehicle as equipped.

lamp.
4. Indicates malfunctioning portion with blinking times of air bag warning lamp in diagnosis mode.
5. Indicates the malfunctioning record by CONSULT-III.

Component DescriptionINFOID:0000000003813933
 Air bag diagnosis sensor units are prepared for operation while the ignition switch is in the ON or START
position.
 The operation of Supplemental Restraint System is different from collision modes application. For example,
the driver air bag module and front passenger air bag module are activated in a frontal collision but not in a
side collision.
 SRS configurations which are activated for some collision modes are as follows.
1. Front passenger air bag module M62 2. Driver air bag module M350 3. Conbination switch (Spiral cable)

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.
CONSULT-III FunctionINFOID:0000000003813935
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.
From Diagnosis Mode to User Mode
To return to User mode from Diagnosis mode, touch “BACK” key of CONSULT-III until “SELECT SYSTEM”
appears, then Diagnosis mode automatically changes to User mode.
DIAGNOSIS MODE FOR CONSULT-III
 “SELF-DIAG [CURRENT]”
Current self-diagnosis results (also indicated with the number of air bag 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 is displayed on CONSULT-III screen. 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 con-
firming this classification number on CONSULT-III screen.
After repair, check that the discriminated number of air bag diagnosis sensor unit installed to vehicle is the
same. Refer to SR-22, "
Exploded View".
HOW TO ERASE SELF-DIAGNOSTIC RESULTS
 “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 illuminating the warning lamp even if the malfunction is repaired completely.
 “TROUBLE DIAG RECORD”
The memory of “TROUBLE DIAG RECORD” cannot be erased.

DescriptionINFOID:0000000003813936
Check the whole SRS and displays the malfunction either by illuminating or blinking the air bag warning lamp
in the combination meter. Malfunctioning part can be detected by on board self-diagnosis system and CON-
SULT-III.
OPERATION
It detects a shock that exceeds a specified level and monitors whether the driver and passenger air bags, front
side air bag, side curtain air bag and pre-tensioner seat belts operate normally.
STRUCTURE
It contains the “G” sensors for both frontal and side collisions and spare battery function in case of main bat-
tery damage in collision.
INSTALLATION
Air bag diagnosis sensor unit is installed under the center console with fixed bolts.
DTC LogicINFOID:0000000003813937
DTC CONFIRMATION PROCEDURE
1.CHECK SELF-DIAG RESULT
With CONSULT-III
1. Turn ignition switch ON.
2. Perform “AIR BAG” Self Diagnostic Result.
Without CONSULT-III
1. Turn ignition switch ON.
2. Check the air bag warning lamp status. Refer to SRC-10, "
Air Bag Warning Lamp Diagnosis".
NOTE:
SRS does not enter Diagnosis mode if no malfunction is detected in User mode.
Is malfunctioning part detected?
YES >> Refer to SRC-16, "Diagnosis Procedure".
NO >> INSPECTION END
Diagnosis ProcedureINFOID:0000000003813938
WARNING:
 Before servicing, turn ignition switch OFF, disconnect battery negative terminal and wait at least 3
minutes. (To discharge backup capacitor.)
 Never use unspecified tester or other measuring device.
1.CHECK HARNESS CONNECTOR
Check the harness connector.
Is the inspection result normal?
YES >> GO TO 2.
NO >> Replace harness connectors.
2.CHECK WIRING HARNESS
Check the wiring harness externals.
