Restraint Systems

DIAGNOSIS:
- Side airbag harness (RH) is faulty.
- Side airbag module (RH) is faulty.
- 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.

5M1: SIDE AIRBAG MODULE INSPECTION
1. Disconnect connector (AB26) from ELR with pretensioner on RH side.
2. Disconnect connector (AB24) and (AB25), and then connect connector (AB24) and test harness F connector (1F).
3. Connect test harness F connector (3F) and air-bag resistor.
4. Connect battery ground cable and then turn ignition switch ON.

CHECK: Does the airbag warning light come on?

YES: Replace front seat with side airbag module (RH).

NO: Go to step 5M2.

5M2: SIDE AIRBAG HARNESS (RH) INSPECTION
1. Turn ignition switch OFF, disconnect battery ground cable and then wait at least 20 seconds.
2. Disconnect test harness F and airbag resistor.
3. Disconnect connector (AB18) from airbag control module and connect test harness I or I2 connector (1I).




4. Measure resistance between test harness I or I2 connector (3I) terminal and test harness F connector (3F) terminal.

CHECK: Is the resistance less than 10 ohms?

YES: Go to step 5M3.

NO: Replace side airbag harness (RH).

5M3: SIDE AIRBAG HARNESS (RH) INSPECTION




Measure resistance between test harness I or I2 connector (3I) terminal and test harness F connector (3F) terminal.

CHECK: Is the resistance less than 10 ohms?

YES: Go to step 5M4.

NO: Replace side airbag harness (RH).

5M4: SIDE AIRBAG HARNESS (RH) INSPECTION




Measure resistance of test harness I or I2 connector (3I) terminal.

CHECK: Is the resistance more than 1 M ohms?

YES: Go to step 5M5.

NO: Replace side airbag harness (RH).

5M5: SIDE AIRBAG HARNESS (RH) INSPECTION




Measure resistance of test harness F connector (3F) terminal.

CHECK: Is the resistance more than 1 M ohms?

YES: Go to step 5M6.

NO: Replace side airbag harness (RH).

5M6: SIDE AIRBAG HARNESS (RH) INSPECTION




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

CHECK: Is the resistance more than 1 M ohms?

YES: Go to step 5M7.

NO: Replace side airbag harness (RH).

5M7: SIDE AIRBAG HARNESS (RH) INSPECTION




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

CHECK: Is the resistance more than 1 M ohms?

YES: Go to step 5M8.

NO: Replace side airbag harness (RH).

5M8: SIDE AIRBAG HARNESS (RH) INSPECTION




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

CHECK: Is the resistance more than 1 M ohms?

YES: Go to step 5M9.

NO: Replace side airbag harness (RH).

5M9: SIDE AIRBAG HARNESS (RH) INSPECTION




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

CHECK: Is the resistance more than 1 M ohms?

YES: Replace airbag control module.

NO: Replace side airbag harness (RH).
