REMOVAL
CAUTION:
lBefore servicing the SRS, turn ignition switch OFF, disconnect both battery cables and wait at
least 3 minutes.
lWhen servicing the SRS, do not work from directly in front of air bag module.
1. Set the front wheels in the straight-ahead position.
2. Remove the steering wheel. Refer toPS-10, "
Removal and Installation".
3. Remove the column cover upper and lower.
4. Disconnect wiper and washer switch connector. Then while
pressing tabs, pull wiper and washer switch away from spiral
cable to remove.

5. Disconnect lighting and turn signal switch connector. Then while
pressing tabs, pull lighting and turn signal switch toward driver
door to remove.
6. Remove the screws. Then while pressing the tab, pull the spiral
cable away from steering column assembly.
CAUTION:
lDo not disassemble spiral cable.
lDo not apply lubricant to the spiral cable.
7. Disconnect the spiral cable connectors.
CAUTION:
With the steering linkage disconnected, the spiral cable
may snap by turning the steering wheel beyond the limited
number of turns. The spiral cable can be turned counter-
clockwise about 2.5 turns from the right end position.
INSTALLATION
Install in the reverse order of removal.
lAlign spiral cable correctly when installing steering wheel, refer
toSRS-39, "
INSTALLATION". Make sure that the spiral cable is
in the neutral position. The neutral position is detected by turn-
ing left 2.6 revolutions from the right end position and ending
with the locating pin at the top.
lReset the steering angle sensor calibration after installing spiral
cable.
lAfter the work is completed, perform self-diagnosis to make sure
no malfunction is detected. Refer toSRS-18, "
SRS Operation
Check".
CAUTION:
lThe spiral cable may snap due to steering operation if the
cable is not installed in the correct position.
lWith the steering linkage disconnected, the cable may snap by turning the steering wheel beyond
the limited number of turns. The spiral cable can be turned counterclockwise about 2.5 turns from
the right end position.
