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

A3U080201046W03

•

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.
