CAUTION / NOTICE / HINT

NOTICE:

• After replacing the airbag ECU assembly, make sure to perform Write VIN/Vehicle Identification Number, ECU Configuration, Update ECU Security Key, and Switching Specification Information.
• After performing the update ECU security key procedure, make sure to perform the initialization procedure for when the cable has been disconnected and reconnected to the negative (-) auxiliary battery terminal.

(1) Install the airbag ECU assembly with the 2 bolts (B).

Torque:

17.5 N·m {178 kgf·cm, 13 ft·lbf}

NOTICE:

• If the airbag ECU assembly has been dropped, or there are any cracks, dents or other defects in the case or connector, replace it with a new one.
• When installing the airbag ECU assembly, make sure that the SRS wiring does not interfere with or is not pinched between other parts.
