Restraint Systems

DIAGNOSIS:
- Airbag control module is faulty.
- Airbag main harness circuit is open.
- Fuse No.8 is blown.
- Body harness circuit is open.

CAUTION: Before performing diagnostics on airbag system, turn ignition switch "OFF", disconnect battery ground cable and then wait at least 20 seconds.
After 20 seconds elapse, remove instrument panel lower cover, and disconnect (AB3) and (AB8).




1. AIRBAG CONTROL MODULE INSPECTION
1. Disconnect connector (AB6) from airbag control module 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 body.

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

2. AIRBAG MAIN HARNESS INSPECTION
1. Go to step 2) below after performing diagnostics on airbag system as per flowchart under "1. Air Bag Control Module Inspection" previously outlined.
2. Turn ignition switch "OFF", disconnect battery ground terminal and then wait at least 20 seconds.




3. Disconnect bulk harness connector (B39) from connector (AB1) at front lower pillar, and connect connector (AB1) 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 Ohm, or less

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

(5A) Terminal / Specified resistance:
No.1 - Body / 10 kOhm, or more

(5B) Terminal / Specified resistance:
No.2 - Body / 10 kOhm, or more

3. FUSE NO.8 INSPECTION




1. Turn ignition switch "OFF", and remove airbag fuse protector.




2. Remove and visually check fuse No.8.
