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 and the seat belt pretensioner LH.	Is there poor contact?	Replace the airbag rear harness along with body harness.	Go to step 2 .
2 CHECK SEAT BELT PRETENSIONER. Turn the ignition switch to OFF, disconnect the battery ground cable, and wait for 60 seconds or more. Disconnect the connector (AB21) from seat belt pretensioner (LH). Connect the connector (1N) in the test harness N to the connector (AB21). 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 six seconds and go off?	Replace the seat belt pretensioner (LH). < Ref. to FRONT SEAT BELT . >	Go to step 3 .
3 CHECK AIRBAG REAR HARNESS (PRE-TENSIONER HARNESS LH). Turn the ignition switch to OFF, disconnect the battery ground cable, and wait for 60 seconds or more. Disconnect the airbag resistor from test harness. Disconnect connector (AB19) from side air-bag module (LH). Disconnect the connector (AB31) from curtain airbag module (LH). 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 (3AG) in the test harness AG and chassis ground. Connector & terminal (3AG) No. 12 - Chassis ground: (3AG) No. 10 - Chassis ground:	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.
