SAS Control Module Removal/Installation [Two-Step Deployment Control System]: Notes
WARNING: This page is about a different car, the 2017 Mazda 3. However, it is still accessible from the selected car via links, so may be relevant.
WARNING:
- Handling the SAS control module improperly can accidentally operate (deploy) the air bag module, pre-tensioner seat belt, and lap pre-tensioner seat belt, which may seriously injure you. Read the air bag system service warnings and cautions before handling the SAS control module. (See AIR BAG SYSTEM SERVICE WARNINGS [TWO-STEP DEPLOYMENT CONTROL SYSTEM] .) (See AIR BAG SYSTEM SERVICE CAUTIONS [TWO-STEP DEPLOYMENT CONTROL SYSTEM] .)
- If the connector is connected and the ignition switch is turned to the ON position with the SAS control module not secured completely using the installation nuts, the SAS control module may detect a degree of impact even when something contacts it lightly, deploying the air bag module, pre-tensioner seat belt and lap pre-tensioner seat belt accidentally.
- If the DSC related parts sensor initialization procedure is not completed, it could result in an unexpected accident due to the DSC being inoperative. Therefore, after the SAS control module is replaced, always perform the DSC related parts sensor initialization procedure to ensure proper DSC operation.
- If the MRCC initial setting is not completed after replacing/removing the SAS control module, the Mazda radar cruise control (MRCC) system will not operate normally which could lead to an unexpected accident. After replacing/removing the SAS control module, always perform the MRCC initial setting to assure proper Mazda radar cruise control (MRCC) system operation.
- If configuration is not performed when the SAS control module is replaced with a new one, the vehicle specification information is not stored in the SAS control module and the system will not operate normally.
CAUTION:
- When replacing the SAS control module, always perform the configuration procedure before removing the SAS control module. If the configuration is not performed and the SAS control module is removed, DTC B0003:53 will be displayed.
- When performing configuration, it is necessary to read the vehicle specification information from the SAS control module before replacing it. Connect the M-MDS to the vehicle and perform vehicle identification before removing the SAS control module. The vehicle specification information is temporarily stored in the M-MDS.
NOTE:
- The SAS control module prior to replacement stores the vehicle specification information.
- A new SAS control module does not store any vehicle specification information.
- If the vehicle specification information from the SAS control module prior to replacement cannot be read, perform the configuration using As-Built data.
