52 - Side Airbag Sensor (LH) Is Faulty

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

CAUTION: Before performing diagnostics on airbag system, turn ignition switch "OFF", disconnect battery ground cable and then wait at least 20 seconds.

5R1: SIDE AIRBAG HARNESS (LH) INSPECTION
1. Disconnect connector (AB21) from ELR with pretensioner on LH side.
2. Disconnect connector (AB19) and (AB20) at below front seat on LH side. (Side airbag equipped vehicle)
3. Disconnect connector (AB17) from airbag control module and connect it to test harness I or I2 connector (1I).
4. Disconnect connector (AB23) from side airbag sensor (LH) and connect it to test harness G connector (1G).




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

CHECK: Is the resistance less than 10 ohms?

YES: Go to step 5R2.

NO: Replace side airbag harness (LH).

5R2: SIDE AIRBAG HARNESS (LH) INSPECTION




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

CHECK: Is the resistance less than 10 ohms?

YES: Go to step 5R3.

NO: Replace side airbag harness (LH).

5R3: SIDE AIRBAG HARNESS (LH) INSPECTION




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

CHECK: Is the resistance less than 10 ohms?

YES: Go to step 5R4.

NO: Replace side airbag harness (LH).

5R4: SIDE AIRBAG HARNESS (LH) INSPECTION




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

CHECK: Is the resistance less than 10 ohms?

YES: Go to step 5R5.

NO: Replace side airbag harness (LH).

5R5: SIDE AIRBAG HARNESS (LH) INSPECTION




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

CHECK: Is the resistance more than 1 M ohms?

YES: Go to step 5R6.

NO: Replace side airbag harness (LH).

5R6: SIDE AIRBAG HARNESS (LH) INSPECTION




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

CHECK: Is the resistance more than 1 M ohms?

YES: Go to step 5R7.

NO: Replace side airbag harness (LH).

5R7: SIDE AIRBAG HARNESS (LH) INSPECTION




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

CHECK: Is the resistance more than 1 M ohms?

YES: Go to step 5R8.

NO: Replace side airbag harness (LH).

5R8: SIDE AIRBAG HARNESS (LH) INSPECTION




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

CHECK: Is the resistance more than 1 M ohms?

YES: Replace side airbag sensor (LH).

NO: Replace side airbag harness (LH).
