FLOWCHART

CAUTION: Before troubleshooting airbag system, disconnect battery ground cable, turn ignition switch "OFF" and then wait at least 10 minutes. After 10 minutes elapse, remove instrument panel lower cover, and disconnect (AB3) and (AB8).

1. AIRBAG CONTROL UNIT INSPECTION





1) Disconnect connector (AB6) from airbag control unit and connect it to test harness-B connector (8B).
2) Connect battery ground cable and turn ignition switch "ON". (engine off)
3) Measure voltage across connector (5B) terminal and GND.

(5B) Terminal / Specified voltage:
No.2 - Body /10 V, min.

2. AIRBAG MAIN HARNESS INSPECTION

1) Go to step 2) below after troubleshooting airbag system as per flowchart under "1 Air Bag Control Unit Inspection" previously outlined.
2) Disconnect battery ground terminal, turn ignition switch "OFF" and then wait at least 10 minutes.





3) Disconnect bulk harness connector (B58) from connector (AB1) at front lower pillar, and connect connector (B58) to test harness-A connector (2A).
4) Measure resistance between test harness-A connector (5A) terminal and test harness-B connector (5B) terminal.

Connector & terminal / Specified resistance:

(5A) No.1 - (5B) No.2/10 Ohms max.

5) Measure resistance between terminals of connectors (5A) and (5B).

(5A) Terminal / Specified resistance:
No.1 - Body /10 K Ohms min.
(5B) Terminal / Specified resistance:
No.2 - Body /10 K Ohms min.

3. FUSE NO.8 INSPECTION





1) Remove airbag fuse protector.





2) Remove and visually check fuse No.8.
