- SRS inflator simulator 07SAZ-TB4011A
- SRS simulator lead H 07YAZ-S3AA100
1. Erase the DTC memory.
2. Turn the ignition switch ON (II), and check that the SRS indicator comes on for about 6 seconds and then goes off.
Does the SRS indicator stay on?

3. Turn the ignition switch OFF. Disconnect the battery negative cable, and wait for 3 minutes.
4. Check the connection between the right side wire harness 2P connector and the front passenger's side impact sensor.
Is the connection OK?
YES - Go to step 5.
NO - Poor contact between the right side wire harness 2P connector and the front passenger's side impact sensor; replace the front passenger's side impact sensor.
