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, side airbag module RH and the side airbag sensor RH.	Is there poor contact?	Replace the airbag rear harness along with body harness.	Go to step 2 .
2 CHECK SIDE AIRBAG MODULE. Turn the ignition switch to OFF, disconnect the battery ground cable, and wait for 60 seconds or more. Disconnect the connector (AB24), and connect the connector (1AJ) in test harness AJ to connector (AB24). Connect the airbag resistor to the test harness AJ connector (3AJ). 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 side airbag module (RH). < Ref. to REMOVAL , Side Airbag Module. >	Go to step 3 .
3 CHECK AIRBAG REAR HARNESS (SIDE 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 the connector (AB33) from curtain airbag module (RH). Disconnect the airbag resistor from test harness. Disconnect the connectors (AB6, AB17, AB18) from airbag control module. Connect the connector (1AG) in the test harness AG to the connectors (AB6, AB17, AB18). Connect the battery ground terminal and turn the ignition switch to ON. Measure the voltage between connector (5AG) in the test harness AG and chassis ground. Connector & terminal (5AG) No. 5 (+) - Chassis ground (-): (5AG) No. 7 {+) - Chassis ground (-):	Is the voltage less than 1 V?	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.
