1.CHECK POOR CONTACT OF CONNECTORS.

Check for poor contact of the connectors between the airbag control module and the side airbag sensor (RH).

Is there poor contact?

Replace the airbag rear harness along with body harness.

Diagnostic Chart with Trouble Code > DTC B1623 SIDE AIRBAG SENSOR RH INITIALIZATION ERROR">Go to Step 2.

2.CHECK AIRBAG REAR HARNESS (BETWEEN AIRBAG CONTROL MODULE AND SIDE AIRBAG SENSOR RH).

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

2) Disconnect the connector (AB26) from seat belt pretensioner (RH).

3) Disconnect the connector (AB33) from curtain airbag module (RH).

4) Disconnect connector (AB24) of the side airbag module (RH).

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

6) Connect the connector (1AG) in the test harness AG to the connectors (AB6, AB17, AB18).

7) Disconnect the connector (AB28) from side airbag sensor (RH), and connect the connector (2V) in test harness V to connector (AB28).

8) 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. 1:
(5AG) No. 16 — (3V) No. 2:

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 RH).

Measure the resistance between connector (3V) in test harness V and chassis ground, and the resistance between connector (3V) terminals in test harness V.

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?

Diagnostic Chart with Trouble Code > DTC B1623 SIDE AIRBAG SENSOR RH INITIALIZATION ERROR">Go to Step 6.

5.REPLACE SIDE AIRBAG SENSOR (RH) 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) Replace 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 the system normal?

Diagnostic Chart with Trouble Code > DTC B1623 SIDE AIRBAG SENSOR RH INITIALIZATION ERROR">Go to Step 6.

Replace the curtain airbag sensor RH. Curtain Airbag Sensor > REMOVAL"> Replace the airbag control module if not operating normally even after replacing the sensor. Airbag Control Module > REMOVAL">

6.CHECK FOR ANY OTHER DTC ON DISPLAY.

Is any other DTC displayed?

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

Finish the diagnosis.
