STEPCHECKYESNO

1.CHECK POOR CONTACT OF CONNECTORS.

Check for poor contact of the connectors between the airbag control module and the side airbag sensor LH.

Is there poor contact-

Replace the airbag main harness along with body harness.

2.CHECK AIRBAG REAR HARNESS (BETWEEN AIRBAG CONTROL MODULE AND SIDE AIRBAG SENSOR LH) (OPEN CIRCUIT).

1) Turn the ignition switch to OFF, disconnect the battery ground cable, and wait for 60 seconds or more.

2) Disconnect the connector (AB21) from seat belt pretensioner LH.

3) Disconnect the connector (AB5) from seat cushion airbag module LH.

4) Disconnect the connector (AB31) from curtain airbag module LH.

5) Disconnect the connector (AB19) from side airbag module LH.

6) Disconnect the connectors (AB6, AB17, AB18) from airbag control module.

7) Connect the connector (1AD) in test harness AD AV to the connectors (AB6, AB17, AB18).

8) Connect the connector (2AD) in test harness AD AV and the connector (1AG) in test harness AG.

9) Disconnect the connector (AB23) from side airbag sensor LH, and connect the connector (2V) in test harness V to connector (AB23).

10) Measure the resistance between connector (5AG) in the test harness AG and connector (3V) in the test harness V.

Connector & terminal

(5AG) No. 14 — (3V) No. 2:

(5AG) No. 16 — (3V) No. 1:

Is the resistance less than 10 --

Replace the airbag rear harness along with body harness.

3.CHECK AIRBAG REAR HARNESS (BETWEEN AIRBAG CONTROL MODULE AND SIDE AIRBAG SENSOR LH) (SHORTED TO GROUND AND SHORTED BETWEEN LINES).

Measure the resistance between test harness AG connectors (5AG) and chassis ground, and the resistance between connectors (5AG) of the test harness AG.

Connector & terminal

(3V) No. 1 — Chassis ground:

(3V) No. 2 — Chassis ground:

(3V) No. 1 — (3V) No. 2:

Is the resistance 1 M- or more-

Replace the airbag rear harness along with body harness.

4.CHECK AIRBAG CONTROL MODULE.

1) Connect all connectors.

2) Clear the memory. Clear Memory Mode

3) Perform the Inspection Mode. Inspection Mode

4) Read the DTC. (Current malfunction) Read Diagnostic Trouble Code (DTC)

Is DTC B16EB displayed-

5.CHECK SIDE AIRBAG SENSOR LH.

1) Turn the ignition switch to OFF, disconnect the battery ground cable, and wait for 60 seconds or more.

2) Replace the side airbag sensor LH by the side airbag sensor RH. Side Airbag Sensor > REMOVAL

3) Connect all connectors.

4) Clear the memory. Clear Memory Mode

5) Perform the Inspection Mode. Inspection Mode

6) Read the DTC. (Current malfunction) Read Diagnostic Trouble Code (DTC)

Is DTC B16EB displayed-

Replace the side airbag sensor LH. Side Airbag Sensor > REMOVAL

6.REPLACE SIDE AIRBAG SENSOR LH AND CHECK AIRBAG CONTROL MODULE AFTER REPLACEMENT.

1) Turn the ignition switch to OFF, disconnect the battery ground cable, and wait for 60 seconds or more.

2) Restore the side airbag sensors RH and LH back to their original position. Side Airbag Sensor > REMOVAL

3) Connect all connectors.

4) Clear the memory. Clear Memory Mode

5) Perform the Inspection Mode. Inspection Mode

6) Read the DTC. (Current malfunction) Read Diagnostic Trouble Code (DTC)

Is DTC B16EB displayed-

Replace the airbag control module. Airbag Control Module > REMOVAL

7.CHECK FOR ANY OTHER DTC ON DISPLAY.

Read the DTC. (Current malfunction) Read Diagnostic Trouble Code (DTC)

Is any other DTC displayed-

Check DTC using “List of Diagnostic Trouble Code”. List of Diagnostic Trouble Code (DTC) > LIST

Finish the diagnosis.
