DIAGNOSTIC PROCEDURE

Step	Check	Yes	No
1 CHECK DTC. Read the DTC. (Current malfunction)	Is DTC B1622 or B1623 displayed?	Perform the diagnosis according to DTC.	Go to step 2 .
2 CHECK DTC. Read the DTC. (Current malfunction)	Is DTC B1632 or B1633 displayed?	Perform the diagnosis according to DTC.	Go to step 3 .
3 CHECK POOR CONTACT OF CONNECTORS. Check for poor contact of the connectors between the airbag control module and the front door impact sensor (RH).	Is there poor contact?	Replace the airbag rear harness and the door harness.	Go to step 4 .
4 CHECK AIRBAG REAR HARNESS AND DOOR HARNESS (BETWEEN CURTAIN AIRBAG SENSOR RH AND DOOR SENSOR RH). Turn the ignition switch to OFF, disconnect the battery ground cable, and wait for 60 seconds or more. Disconnect the connector (AB26) from seat belt pretensioner (RH). Disconnect the connector (AB33) from curtain airbag module (RH). Disconnect connector (AB24) from side airbag module (RH). Disconnect the connector (AB34) from curtain airbag sensor (RH), and connect the connector (2V) in test harness V to connector (AB34). Disconnect the connector (AB64) from the front door impact sensor (RH), and connect the connector (1H) in the test harness H to connector (AB64). Measure the resistance between connector (3V) in the test harness V and connector (3H) in the test harness H. Connector & terminal (3V) No. 4 - (3H) No. 5: (3V) No. 5 - (3H) No. 6:	Is the resistance less than 10 Ω?	Go to step 5 .	Check the door harness, and if any fault is found, replace the harness. If there is no fault, replace the airbag rear harness together with body harness.
5 CHECK AIRBAG REAR HARNESS AND DOOR HARNESS (BETWEEN CURTAIN AIRBAG SENSOR RH AND DOOR 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. 4 - Chassis ground: (3V) No. 5 - Chassis ground: (3V) No. 4 - (3V) No. 5:	Is the resistance 1 MΩ or more?	Go to step 6 .	Check the door harness, and if any fault is found, replace the harness. If there is no fault, replace the airbag rear harness together with body harness.
6 CHECK AIRBAG CONTROL MODULE. Connect all connectors. Clear the memory. Perform the Inspection Mode. Read the DTC. (Current malfunction)	Is the same DTC displayed?	Go to step 7 .	Go to step 9 .
7 REPLACE FRONT DOOR IMPACT SENSOR (RH) AND CHECK AIRBAG CONTROL MODULE AFTER REPLACEMENT. Turn the ignition switch to OFF, disconnect the battery ground cable, and wait for 60 seconds or more. Replace the front door impact sensor (RH). Refer to REMOVAL . Connect all connectors. Clear the memory. Perform the Inspection Mode. Read the DTC. (Current malfunction)	Is the same DTC displayed?	Go to step 8 .	Go to step 9 .
8 REPLACE CURTAIN AIRBAG SENSOR (RH) AND CHECK AIRBAG CONTROL MODULE AFTER REPLACEMENT. Turn the ignition switch to OFF, disconnect the battery ground cable, and wait for 60 seconds or more. Replace the curtain airbag sensor (RH). Refer to REMOVAL . Connect all connectors. Clear the memory. Perform the Inspection Mode. Read the DTC. (Current malfunction)	Is the same DTC displayed?	Replace the airbag control module. Refer to REMOVAL .	Go to step 9 .
9 CHECK FOR ANY OTHER DTC ON DISPLAY.	Is any other DTC displayed?	Check DTC using "List of Diagnostic Trouble Code". Refer to LIST .	Finish the diagnosis.
