1. CHECK FUSE AND FUSIBLE LINK
Check that the following fuse and fusible link are not blown.
Is the fuse or fusible link blown?
YES >> Replace the blown fuse or fusible link after repairing the affected circuit.
NO >> GO TO 2
2. CHECK POWER SUPPLY CIRCUIT
1. Disconnect BCM connector M21.
2. Check voltage between BCM connector M21 terminals 131, 139 and ground.
Is the inspection result normal?
YES >> GO TO 3
NO >> Repair or replace harness or connectors.
3. CHECK GROUND CIRCUIT
Check continuity between BCM connector M21 terminals 134, 143 and ground.
Is the inspection result normal?
YES >> Inspection End.
NO >> Repair or replace harness or connectors.

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".
