DTC 12
DIAGNOSIS:- Airbag main harness circuit is open, shorted or shorted to ground.
- Airbag module harness (Passenger) circuit is open, shorted or shorted to ground.
- Airbag control module 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).
5C1: AIRBAG MAIN HARNESS INSPECTION
1. Remove glove box.
2. Disconnect connector (AB9) and (AB10) and connect connector (AB9) to test harness F connector (1F).
3. Disconnect connector (AB6) from airbag control module, and connect it to test harness I or I2 connector (1I) terminal.
4. Measure resistance between test harness I or I2 connector (2I) and test harness F connector (3F) terminals.
CHECK: Is resistance less than 10 ohms?
YES: Go to step 5C2.
NO: Replace airbag main harness.
5C2: AIRBAG MAIN HARNESS INSPECTION
Measure resistance between test harness I or I2 connector (2I) and test harness F connector (3F) terminals.
CHECK: Is resistance less than 10 ohms?
YES: Go to step 5C3.
NO: Replace airbag main harness.
5C3: AIRBAG MAIN HARNESS INSPECTION
1. Disconnect connector (AB6) from airbag control module , and connect it to test harness I or I2 connector (1I).
2. Measure resistance between test harness I or I2 connector (2I) terminal.
CHECK: Is resistance more than 10 kg?
YES: Go to step 5C4.
NO: Replace airbag main harness.
5C4: AIRBAG MAIN HARNESS INSPECTION
1. Disconnect connector (AB6) from airbag control module and connect it to test harness I or I2 connector (1I).
2. Measure resistance between test harness I or I2 connector (2I) terminals and chassis ground.
CHECK: Is resistance more than 1 M ohms?
YES: Go to step 5C5.
NO: Replace airbag main harness.
5C5: AIRBAG MAIN HARNESS INSPECTION
Measure resistance between test harness I or I2 connector (2I) terminals and chassis ground.
CHECK: Is resistance more than 1 M ohms?
YES: Replace airbag control module.
NO: Replace airbag main harness.
