Post-repair Operation
Past malfunction code display cancellation

Caution

••••

Connecting the wrong DLC terminal may possibly cause a malfunction. Carefully connect the 
specified terminal only.

1. Turn the ignition switch to the ON position.
2. Wait until the air bag system warning light illuminates approximately 6 seconds and goes off.
3. Perform both the following steps alternately three 

times each at 0.5—1.5 seconds intervals.
(1) Use a jumper wire to short the DLC terminal 

SCN to body GND.

(2) Disconnect the jumper wire from body GND.

4. If the DTCs are displayed, wait until they 

disappear.

5. Using a jumper wire, short the DLC terminal SCN 

to body GND to verify that the DTCs of the past 
malfunction are not displayed.

•

If the DTCs are still displayed, perform the 
past malfunction display cancellation again.

6. Turn the ignition switch to the LOCK position.
7. Disconnect the jumper wire from the DLC.

DTC TABLE

•

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.

•

After a new SAS control module is installed, the air bag system warning light continuously flashes when 
the ignition switch is turned to ON position. This is the deployment authorization standby code output by 
the SAS control module. Perform the deployment authorization and restore the system to an operational 
state.

•

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.
