251Section 2 TroubleshootingI. LIST OF TROUBLES1. SRS warning light OFFDIAGNOSTIC PROCEDURESWhen performing the first diagnostic check, it is advised to shake slightly the harness and connector to see if
there is any discontinuous poor contact in circuit. If there is such a problem, make sure that the connections
of the connector, terminals and wire harness are correct and undamaged. Otherwise, follow these procedures:
(1) Check other wire harnesses and instrument cluster indicator lights
1Turn the ignition switch ON.
2Any other light on?
Yes: turn the ignition switch to LOCK, and continue with the next step.
No: check the power supply and ground system (fuse) of the instrument cluster, and continue with step 5.
(2) Check light bulb
CAUTION:
Mishandling of SRS components may release unexpectedly airbag and seat belt pretensioner, probably lead-
ing to a serious accident. Read the service cautions before handling a SRS component.
1Turn the ignition switch to LOCK.
2Disconnect the negative (-) terminal cable from the battery and wait for at least 60s.
3Remove the instrument cluster.
4Measure and see if the two pins of the SRS warning light is triggered.
Yes: continue with next step.
No: replace the bulb of the warning light.

262Section 3 Removal & InstallationI. SRS ELECTRONICAL CONTROL UNIT (ECU)1. Operations prior to Removal
(1) Turn the ignition switch OFF.
(2) Remove negative (-) terminal cable of the battery. Put it in a proper position or wrap it up with insulating
tape.
2. Removal procedures:
(1) Remove the central passage side cover plate (or remove auxiliary console).
(2) Remove the connectors to SRS ECU.
(3) Remove ECU.
3. Installation procedures:
(1) Install ECU.
(2) Install the connectors to SRS ECU.
(3) Install the central passage side cover plate (or install auxiliary console).
(4) Connect negative (-) terminal cable of the battery.
4. Key points for Installation:
(1) Install ECU.
(2) Check after installation.
1Turn the ignition switch ON.
2The warning light goes on within 6s, and then goes out.
(3) If the light doesn't go out, check the trouble and eliminate it.NOTICE1. Work must be started 60s after the negative (-) terminal cable is detached from battery. The detachednegative (-) terminal cable shall be protected with insulating tape for insulation.
2. Never attempt to dismantle or repair an ECU. If there is any trouble, replace the ECU with a new one.
3. Prevent the ECU from shock or vibration. If pitting, crack or distortion is found, replace the ECU with
a new one.
4. Every time an airbag is deployed, the ECU shall be replaced with a new one.
5. When disassembling or maintaining the parts around ECU, attention must be given to avoid contacting
the ECU.NOTICE
If the ECU cannot be installed correctly, the airbag will not act normally.

265III. KEY POINTS FOR INSTALLATION1. Pre-Check
(1) The new airbag or clock spring shall be checked before being installed.
(2) Connect negative (-) terminal cable of the battery.
(3) Connect Hi-DS T to the diagnostic interface (16 connector).
(4) Turn the ignition switch ON.
(5) Read the diagnostic circuit and see if the other locations than the troubled area of the airbag are normal.
(6) Turn the ignition switch ON.
(7) Remove the negative (-) terminal cable from the battery, and protect it with insulating tape for insulation.
2. Installation of clock spring: align the clock spring and install it to the
steering wheel.
yCenter alignment of the clock spring
Screw up the clock spring clockwise to the end, rotate it counterclock-
wise by 2.5 turns, and align it with the mark (see the figure below).
3. Install the components of the steering wheel and airbag assembly
(1) When the center of the clock spring is aligned, install the components of the steering wheel and airbag
assembly.
(2) After being installed, rotate the left and right sides of the steering wheel to position, and make sure there
is no abnormality.NOTICEIn case of scrapping an airbag, it shall be noted that the airbag shall be deployed according to the specifiedprocedures before being scrapped.
When connecting or disconnecting the Hi-DS T, turn the ignition switch OFF first.NOTICE:
Work must be started 60s after the negative (-) terminal cable is disconnected from battery.NOTICE:
If the center of the clock spring cannot be aligned, the steering wheel
will not turn midway, or cause bad performance to the clock spring
circuit, consequently hamper the normal action of the airbag.NOTICEWhen installing the components of the steering wheel and airbag assembly, attention should be given toprotect the wire harness of the clock spring from seizure.

2702Prepare two 6m plus wire harnesses for deployment, connect the other two ends to avoid unexpected
deployment in case of static electricity (see the figure below).
3Touch the body of the vehicle with hands for static electricity elimination.
NOTICE:
The above-mentioned procedures can prevent the unexpected deployment due to static electricity and shall
therefore be performed strictly.
4Cut off the wire harnesses of the driver airbag assembly and connect them with the two wire harnesses
for deployment, and make sure to wrap up the connecting location with insulating tape for insulation (see
the figure below).
5Install the unused bolts on to the inside bolt of the driver airbag assembly, and tie a thick wire securing the
wheel rim.
6Pass the deployment wire harness of the driver airbag assembly through an old tire with rim, and fix
upwards the driver airbag assembly by means of the wire connected to the bolts, etc (see the figure
below).Wire Harness

337(8) Make sure the warning light of the airbag system on for 6s and off.
If the warning light of the airbag system is not as specified, it means system fault. Check with the OBD (on-
board diagnostics).4.Rear Seat Belt Removal / InstallationWarning
Do not remove retractor.
(1) Fold rear seat back.
(2) Remove B pillar upper inside trim.
(3) Remove rear trunk partition.
(4) Remove bolt.
(5) Remove rear seat belt.
(6) The installation is in the reverse order of the removal.
5.Rear Seat Belt Buckle Removal / Installation
(1) Remove rear seat cushion.
(2) Remove the bolt.
(3) Remove rear seat belt buckle.
(4) The installation is in the reverse order of the removal.
6. Seat Belt Inspection
(1) Ensure correct installation of seat belt.

(3) If the vehicle has been vibrated during the accident, pull out the
seat belt from the retractor, observe by eye and touch the seat
belt with hand to ensure that there is no scratch (load limit retractor
does not operate).
