WARNING: This page is about a different car, the 2005 Mazda 6. However, it is still accessible from the selected car via links, so may be relevant.
- DTCs are common for present and past malfunction diagnosis.NOTE:
- When DTCs not shown in the DTC table are displayed, replace the SAS control module.
- If the air bag system warning light does not illuminate or remains illuminated when the ignition switch is turned to the ON position, inspect and repair the air bag system warning light circuitry and then confirm that the air bag system warning light is operational.
- The air bag system warning light will flash the DTC pattern for five cycles, and then it will remain illuminated until the ignition switch is turned to the LOCK position.
