• 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 circuit, and then confirm that 
the air bag system warning light is operational.

• The air bag system warning light flashes the DTC pattern for five cycles, and then remains illuminated 

until the ignition switch is turned to the ACC or LOCK position.
