NOTE: Before troubleshooting any of these DTCs, check the battery/system voltage. If the voltage is low, repair the charging system or replace the battery before troubleshooting the SRS.

2. Turn the ignition switch ON (II), and check that the SRS indicator comes on for about 6 seconds and then goes off.
