3.CHECK AIRBAG REAR HARNESS (BETWEEN SIDE AIRBAG SENSOR LH AND CURTAIN AIRBAG SENSOR LH) (OPEN CIRCUIT).

1) Turn the ignition switch to OFF, disconnect the battery ground cable, and wait for 60 seconds or more.

2) Disconnect the connector (AB21) from seat belt pretensioner LH.

3) Disconnect the connector (AB5) from seat cushion airbag module LH.

4) Disconnect the connector (AB31) from curtain airbag module LH.

5) Disconnect the connector (AB19) from side airbag module LH.

6) Disconnect the connector (AB23) from the side airbag sensor LH.

7) Connect the connector (AB23) of side airbag sensor LH and the connector (1AI) in the test harness AI.

8) Connect the connector (2AI) in the test harness AI and the connector (1V) in the test harness V.

9) Disconnect the connector (AB32) from curtain airbag sensor LH, and connect the connector (2V) in test harness V to connector (AB32).

10) Measure the resistance between connector (3V) terminals in the test harness V.

Connector & terminal

(3V) No. 2 — (3V) No. 6:

(3V) No. 1 — (3V) No. 7:

Is the resistance less than 10 --
