Removal and InstallationINFOID:0000000009462046
REMOVAL
CAUTION:
• Before servicing, turn the ignition switch OFF, disconnect both battery terminals and wait at least
three minutes.
• Do not use air tools or electric tools for servicing.
1. Disconnect both the negative and positive battery terminal s, then wait at least three minutes. Refer to PG-
73, "Removal and Installation (Battery)".
2. Remove the steering column covers. Refer to IP-17, "Removal and Installation"
.
3. Rotate steering wheel clockwise to access first combination switch bolt and remove.
4. Rotate steering wheel counter-clockwise to access second combination switch bolt and remove.
5. Disconnect the harness connector from the combination switch and remove.
INSTALLATION
Installation is in the reverse order of removal.
CAUTION:
• After the work is completed, make sure no system malfunction is detected by air bag warning lamp.
• In case a malfunction is detected by the air bag wa rning lamp, reset with the self-diagnosis function
and delete the memory with CONSULT.
• If a malfunction is still detected after the above operation, perform self-diagnosis to repair malfunc-
tions. Refer to SRC-42, "ADDITIONAL SERVICE WHEN RE PLACING CONTROL UNIT : Special Repair
Requirement".
