Restraint Systems

DIAGNOSIS:
- Side airbag harness (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.

5O1: 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 5O2.

5O2: 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 it to test harness I or I2 connector (1I).
4. Connect battery ground cable and turn ignition switch ON. (engine off)




5. Measure voltage across connector (3I) terminal and chassis ground.

CHECK: Is the voltage less than 1 V?

YES: Replace airbag control module.

NO: Go to step 5O3.

5O3: SIDE AIRBAG HARNESS (RH) INSPECTION




Measure voltage across connector (3I) terminal and chassis ground.

CHECK: Is the voltage less than 1 V?

YES: Replace airbag control module.

NO: Replace side airbag harness (RH).
