Removal and Installation

WARNING:
• Before servicing, turn ignition switch OFF, disconnect battery negative terminal and wait 3 minutes or more.

• Before disconnecting the air bag sensor unit harness connector, be sure to disconnect the each harness connector of the air bag module and pre-tensioner seat belt to prevent air bag deployment by static electricity and pre-tensioner seat belt operation.

• Never use the air tools or electric tools for servicing.

• When replacing the air bag diagnosis sensor unit, always check with the parts department for the latest 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-tensioners in a collision resulting in serious personal injury or death.

REMOVAL

1. Always check the air bag diagnosis sensor unit ECU discriminated number (identification number) using CONSULT-III.

2. Disconnect the each connector of all air bag modules and pre-tensioner seat belts.

3. Remove the center console assembly. Refer to IP-23, "Removal and Installation".

4. Disconnect the diagnosis sensor unit harness connectors (A).

5. Remove the diagnosis sensor unit mounting bolts (B), and then remove the diagnosis sensor unit.

CAUTION:
• Never impact the diagnosis sensor unit.

• Replace the diagnosis sensor unit if it has been dropped or sustained an impact.

• Replace the diagnosis sensor unit of deployed SRS air bag and deployed SRS front seat belt pre-tensioner.

INSTALLATION

Note the following items, and then install in the reverse order of removal.

CAUTION:
• Never use the old bolts after removal, replace with the new bolts.

• Never damage the harness while installing.

• If malfunction is detected by the air bag warning lamp, after repair or replacement of the malfunctioning parts, reset the memory using self-diagnosis or CONSULT-III. Refer to SRC-12, "On Board Diagnosis Function" or SRC-16, "CONSULT-III Function".

• After the work is completed, check that no system malfunction is detected by air bag warning lamp.

• After replacing the air bag diagnosis sensor unit, confirm using CONSULT-III that the ECU discriminated number (identification number) of the new replacement air bag sensor unit matches the ECU discriminated number (identification number) of the replaced (old) air bag diagnosis sensor unit.

NOTE:

If the ECU discriminated number of the new replacement air bag diagnosis sensor unit differs from the ECU discriminated number of the replaced air bag diagnosis sensor unit, reconfirm the parts information and verify that the correct air bag diagnosis sensor unit was installed.
