25 Side Airbag Sensor (LH) Is Faulty

DIAGNOSIS:
- Side airbag sensor (LH) is faulty.
- Airbag main harness is faulty.

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), (AB9) and (AB10).

5N1: AIRBAG MAIN HARNESS INSPECTION
1. Disconnect connector (AB17) from airbag control module and connect it to test harness E connector (1E).
2. Disconnect connector (AB23) from airbag control module and connect it to test harness G connector (1G).




3. Measure resistance between test harness E connector (3E) terminal and test harness G connector (3G) terminal.

CHECK: Is the resistance less than 10 Ohms?

YES: Go to step 5N2.

NO: Replace airbag main harness.

5N2: AIRBAG MAIN HARNESS INSPECTION.




Measure resistance between test harness E connector (3E) terminal and test harness G connector (3G) terminal.

CHECK: Is the resistance less than 10 Ohms?

YES: Go to step 5N3.

NO: Replace airbag main harness.

5N3: AIRBAG MAIN HARNESS INSPECTION




Measure resistance between connector (3G) terminal and chassis ground.

CHECK: Is the resistance more than 1 M Ohm?

YES: Go to step 5N4.

NO: Replace airbag main harness.

5N4: AIRBAG MAIN HARNESS INSPECTION




Measure resistance between connector (3G) terminal and chassis ground.

CHECK: Is the resistance more than 1 M ohm?

YES: Go to step 5N5.

NO: Replace airbag main harness.

5N5: AIRBAG MAIN HARNESS INSPECTION




Measure resistance between connector (3E) terminal and chassis ground.

CHECK: Is the resistance more than 1 M Ohm?

YES: Go to step 5N6.

NO: Replace airbag main harness.

5N6: AIRBAG MAIN HARNESS INSPECTION




Measure resistance between connector (3E) terminal and chassis ground.

CHECK: Is the resistance more than 1 M Ohm?

YES: Replace side airbag sensor (LH).

NO: Replace airbag main harness.
