A: REMOVAL
WARNING:
Before servicing, be sure to read the notes in
the AB section for proper handling of the driv-
er’s airbag module. General Description.>
1) Set the front wheels in straight ahead position.
2) Turn the ignition switch to OFF.
3) Disconnect the ground cable from battery and
wait for at least 20 seconds before starting work.
4) Using the TORX
® BIT T30 (Tamper resistant type),
loosen the two TORX® bolts which secure driver’s air-
bag module.
5) Disconnect the airbag module connector on
back of airbag module.
6) Remove the horn switch from steering wheel as
shown.7) Disconnect the horn and cruise control com-
mand switch connector, then remove the cruise
control command switch.
B: INSTALLATION
Install in the reverse order of removal.
C: INSPECTION
Measure the cruise control command switch resis-
tance.
If NG, replace the cruise control command switch.
