DIAGNOSTIC PROCEDURE CHART

Step	Check	Yes	No
1 CHECK POOR CONTACT OF CONNECTORS. Check for poor contact of the connectors between the airbag control module, curtain air-bag module RH and the curtain airbag sensor RH.	Is there poor contact?	Replace the airbag rear harness along with body harness.	Go to step 2 .
2 CHECK CURTAIN AIRBAG MODULE. Turn the ignition switch to OFF, disconnect the battery ground cable, and wait for 60 seconds or more. Disconnect the connector (AB33) from curtain airbag module (RH). Connect the connector (1N) in the test harness N to the connector (AB33). Connect the airbag resistor to the connector (2N) of test harness N. Connect the battery ground terminal and turn the ignition switch to ON.	Does the airbag warning light illuminate for 6 seconds and go off?	Replace the curtain airbag module (RH). < Ref. to CURTAIN AIRBAG MODULE . >	Go to step 3 .
3 CHECK AIRBAG REAR HARNESS (CURTAIN AIRBAG MODULE HARNESS 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 connector (AB24) from side air-bag module (RH). Disconnect the airbag resistor from test harness N. Disconnect the connectors (AB6, AB17, AB18) from airbag control module. Connect the connector (1 AG) in the test harness AG to the connectors (AB6, AB17, AB18). Measure the resistance between connector (6AG) terminals in test harness AG. Connector & terminal (6AG) No. 6 - (6AG) No. 8:	Is the resistance 1 MΩ or more?	Go to step 4 .	Replace the airbag rear harness along with body harness.
4 CHECK AIRBAG CONTROL MODULE. Connect all connectors. Clear the memory. Perform the Inspection Mode. Read the DTC.	Is the same DTC displayed?	Replace the airbag control module. < Ref. to AIRBAG CONTROL MODULE . >	Go to step 5 .
5 CHECK FOR ANY OTHER DTC ON DISPLAY.	Is any other DTC displayed?	Check DTC using "List of Diagnostic Trouble Code (DTC)". < Ref. to LIST OF DIAGNOSTIC TROUBLE CODE (DTC) . >	Finish the diagnosis.
