Note
• When DTCs not shown in the DTC table are displayed, replace the SAS unit.
• If the air bag system warning light does not illuminate or remains illuminated when the ignition switch is
turned to 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 will remain illuminated
until the ignition switch is turned to the LOCK position.
