SAS CONTROL MODULE REMOVAL/INSTALLATION

id081000801400

Warning

• Handling the SAS control module improperly can accidentally deploy the air bag modules and pre-

tensioner seat belt, which may seriously injure you. Read the air bag system service warnings and
cautions before handling the air bag module. (See 08-10-3 AIR BAG SYSTEM SERVICE
WARNINGS.) (See 08-10-5 AIR BAG SYSTEM SERVICE CAUTIONS.)

• Connecting the SAS control module with the SAS control module not securely fixed to the vehicle

is dangerous. When the ignition switch is turned to the ON position, the SAS control module could
tilt causing the SAS control module to detect that the vehicle is in a rollover condition, which may
accidentally operate (deploy) the curtain air bag module and pre-tensioner seat belt. Therefore,
before turning the ignition switch to the ON position with the connector connected, securely fix
the SAS control module to the vehicle.

Caution

• Handling the SAS control module improperly can accidentally deploy the air bag modules and pre-

tensioner seat belt, which may seriously injure you. If configuration is not completed before
removing the SAS control module, DTC B2477 or B1017 will be displayed.

1. Perform SAS control module configuration when replacing it. (See 08-10-11 SAS CONTROL MODULE

CONFIGURATION.)

2. Turn the ignition switch to the LOCK position.
