REMOVAL
CAUTION:
• Before servicing the SRS, turn the ignition switch off, disconnect both battery cables and wait at least 3 minutes.
• Do not use old bolts; replace with new bolts.
• Check diagnosis sensor unit bracket to make sure it is free of deformities, dents, cracks or rust. If it
shows any visible signs of damage, replace with new one.
• Replace diagnosis sensor unit if it has been dropped or sustained an impact.
• When replacing the air bag diagno sis sensor unit, always check with the parts department for he lat-
est parts information. Installing an incorrect air bag diagnosis sensor unit may or may not cause the
air bag warning lamp to illuminate and may cause incorrect deployment of the supplemental air bags
and seat belt pre-tensioner in a collision r esulting in serious personal injury or death.
1. Always check the air bag diagnosis sensor unit E CU discriminated number (identification number) using
CONSULT-III.
2. Disconnect the negative and positive battery term inals, then wait at least three minutes.
3. Disconnect the harness connectors for each air bag module and seat belt pre-tensioner.
4. Remove center console. Refer to IP-20, "
Removal and Installation".
5. Disconnect diagnosis sensor unit harness connectors.
6. Remove bolts from the diagnosis sensor unit.
INSTALLATION
Installation is in the reverse order of removal.
• After the work is completed, perform self-diagnosis to check that no malfunction is detected. Refer to SRC-
13, "SRS Operation Check".
CAUTION:
• After replacing the air bag diagnosis sensor unit, confirm using CO NSULT-III that the ECU discrimi-
nated number (identification number) of the ne w replacement air bag diagnosis sensor unit matches
the ECU discriminated number (identification numb er) of the replaced (old) air bag diagnosis sensor
unit.
• The diagnosis sensor unit must always be installed with the arrow mark " ⇐" pointing toward the
front of the vehicle for proper operation.
