2. Turn the ignition switch ON (II), then wait for 10 seconds.
3. Read the DTC (see CLEAR THE DTC MEMORY WITH THE HDS).

Is DTC 46-11 indicated?

YES -Go to step 5.

NO -Go to step 4.

4. Read the DTC.

Is DTC 46-12 also indicated?

YES -Faulty right side impact sensor (second); replace the right side impact
sensor (second) (see SIDE IMPACT SENSOR (SECOND)
REPLACEMENT).

TROUBLESHOOTING INTERMITTENT FAILURES. If another DTC is
indicated, troubleshoot the DTC.

5. Turn the ignition switch OFF.
6. Disconnect the negative cable from the battery, then wait for 3 minutes.
7. Disconnect the floor wire harness 2P connector (A) from the right side impact

sensor (second).
