Warning
-
• Handling the driver-side air bag module improperly can accidentally operate (deploy) the air bag module, which may seriously injure you. Read the SRS air bag system service warnings and cautions before handling the air bag module. (See
AIR BAG SYSTEM SERVICE WARNINGS.) (See
AIR BAG SYSTEM SERVICE CAUTIONS.)
-
Caution
-
• Never remove bolts and screws other than the bolt in Steps 10 and 11. Otherwise, it will cause internal damage and the steering lock cannot be unlocked, resulting in the inability to perform the start-stop unit removal/installation.
• If configuration is not performed when the start stop unit is replaced with a new one, the vehicle specification information is not stored in the start stop unit and the system will not operate normally.
• When performing configuration, it is necessary to read the vehicle specification information from the start stop unit before replacing it. Connect the M-MDS to the vehicle and perform vehicle identification before removing the start stop unit. The vehicle specification information is temporarily stored in the M-MDS.
-
Note

• A new start stop unit does not store any vehicle specification information.
• If the vehicle specification information from the start stop unit prior to replacement cannot be read, perform the configuration using As-Built data.
