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.

2635. Check:
1 ECU case for pitting, crack and distortion.
2 The joint for damage and distortion.
For other ECU checkings, see Troubleshooting.II. AIRBAG ASSEMBLY & CLOCK SPRING1. Operations prior to removal
(1) Take out the ignition key after the steering wheel and front wheel are adjusted to straightforward direction.
(2) Remove negative (-) terminal cable from the battery.
2. Removal procedures of the driver airbag assembly:
(1) Unscrew the screws of the two sides.
(2) Disconnect the connector of the wire harness.
(3) Remove the components of airbag assembly.
(4) Remove steering wheel.
3. Removal procedures of clock spring:
(1) Remove the driver airbag assembly (disconnect the connector).
(2) Remove steering wheel gently (see the precautions).
(3) Open the upper closure of the combination switch, locate and
disconnect the connector of wire harness in the lower end.
(4) Remove clock spring from the steering wheel.
4. Installation procedures of the driver airbag assembly
(1) Pre-Check
ySteering wheel
yConnect the wire harness
yDriver airbag assembly
(2) Screw up the installation screws of the two sides.
(3) Connection of the negative (-) terminal of the battery
(4) Check after installation.NOTICE
If pitting, crack or distortion is found on an ECU, replace it with a new one.NOTICE
Put the removed driver airbag
assembly upside down in a clean
and dry place for care.NOTICE
Put the removed clock spring in
a clean and dry place for care.

2645. Installation procedures of clock spring:
(1) Pre-Check
yThread the line at the upper end of the clock spring through hole on the body part of the steering
wheel
yConnection and fixation of the clock spring and steering wheel
(2) Install the upper hood of the combination switch
(3) Install the steering wheel
(4) Install the airbag assembly components
(5) Connect the negative (-) terminal cable of the battery
(6) Check after installation
6. Removal of steering wheel (see the figure below)
(1) Remove the installation screws from the middle and remove the steering wheel.(Disconnect the horn
connector)
NOTICE:
Due to the tight engagement of the spline and the steering column, it is hard to separate the steering wheel
from the column. Don't try to remove the steering wheel by force (otherwise the clock spring under the
steering wheel will be damaged). The correct way is to turn the nut on the steering column shaft end for
several pitchs and then lift the steering wheel upward.Use Allen
Key Socket

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.

276Section 2 ABS System CheckI. DTC Problem Inspection TableNote: If the Battery is excessively discharged, the motor will not be driven, therefore you must
check that the battery voltage is normal before performing the motor driving test. The vehicle
must be stationary during the test. 1 DTC 01276 Like ly Causes
