DEPLOYMENT OF AIR BAG MODULE AND SEAT BELT
PRE-TENSIONER WHILE MOUNTED IN VEHICLE
When disposing of a vehicle, deploy air bag modules and seat belt
pre-tensioners while they are mounted in vehicle.
CAUTION:
When deploying air bag module or seat belt pre-tensioner,
ensure vehicle is empty.
1. Disconnect both the vehicle battery cables and wait 3 minutes.
2. Disconnect air bag modules and seat belt pre-tensioners con-
nector.
3. Connect deployment tool (SST: KV99106400) to air bag mod-
ule or seat belt pre-tensioner.
For front passenger air bag module and seat belt pre-tensioner,
attach deployment tool adapter (SST: KV99108300 and
KV999R0020) to the tool connector.
4. Connect red clip of deployment tool to battery positive terminal
and black clip to negative terminal.
5. The lamp on the right side of the tool, marked ``deployment tool
power'', should glow green, not red.
6. Press the button on the deployment tool. The left side lamp on
the tool, marked ``air bag connector voltage'', will illuminate and
the air bag module or seat belt pre-tensioner will deploy.
CAUTION:
Activate only one passenger air bag module or seat belt pre-
tensioner at a time.
DISPOSING OF AIR BAG MODULE AND SEAT BELT
PRE-TENSIONER
Deployed air bag modules and seat belt pre-tensioners are very
hot. Before disposing of air bag module, and seat belt pre-
tensioner, wait at least 30 minutes, and 10 minutes, respectively.
Seal them in a plastic bag before disposal.
CAUTION:
+Never apply water to a deployed air bag module and seat
belt pre-tensioner.
+Be sure to wear gloves when handling a deployed air bag
module and seat belt pre-tensioner.
+No poisonous gas is produced upon air bag module
deployment. However, be careful not to inhale gas since it
irritates throat and can cause choking.
+Do not attempt to disassemble air bag module and seat
belt pre-tensioner.
+Air bag module and seat belt pre-tensioner cannot be re-
used.
+Wash your hands clean after ®nishing work.

HOW TO ERASE SELF-DIAGNOSIS RESULTS
With CONSULT
+``SELF-DIAG [CURRENT]''
A current Self-diagnosis result is displayed on the CONSULT 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 screen by
pushing ``BACK'' key of CONSULT 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.
Without CONSULT
After a malfunction is repaired, return to User mode from Diagnosis mode by switching the ignition ``OFF'' for
at least 1 second, then back ``ON''. At that time, the problem code is cleared.
How to Perform Trouble Diagnoses 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 problem. It is important to fully understand the symptoms
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.

If no self-diagnostic failure is detected on ``SELF-DIAG [CUR-
RENT]'' even though malfunction is detected in SRS Operation
Check (User mode), check the battery voltage. If the battery volt-
age is less than 9V, charge the battery. Then go to DIAGNOSTIC
PROCEDURE 3, page RS-34. If the battery voltage is OK, go to
DIAGNOSTIC PROCEDURE 4, page RS-36, to diagnose the fol-
lowing cases:
+Self-diagnostic failure ``SELF-DIAG [PAST]'' (previously stored
in the memory) might not be erased after repair.
+The SRS system malfunctions intermittently.
8. Touch ``PRINT''.
9. Compare diagnostic codes to ``CONSULT DIAGNOSTIC CODE
CHART'', page RS-33.
10. Touch ``BACK'' key of CONSULT until ``SELECT SYSTEM''
appears in order to return to User mode from Diagnosis mode,
then turn off CONSULT.
11. Turn ignition switch ``OFF'', then disconnect CONSULT and
both battery cables.
12. Repair the system as outlined by the ``Repair order'' in ``CON-
SULT DIAGNOSTIC CODE CHART'', that corresponds to the
problem code. For replacement procedure of component parts,
refer to RS-12.
13. After repairing the system, go to DIAGNOSTIC PROCEDURE
3, page RS-34 for ®nal checking.
CONSULT can only show one seat belt pre-tensioner malfunc-
tion as self-diagnosis result at a time. Check self-diagnosis
result with CONSULT whether other malfunctions are detected
after repairing one seat belt pre-tensioner malfunction.
