Schematic Diagram

Monitor Scantool Data

1.	Ignition "OFF", connect scantool.

2.	Ignition "ON" & Engine "OFF", select "Diagnostic Trouble Codes(DTC)" mode.

3.	Monitor diagnostic trouble code and present of trouble code.

4.	Using a scan tool, clear the DTC.

5.

Is DTC present problem ? ▶ Go to "W/Harness Inspection" procedure. ▶ Displaying nothing(no DTC) or DTC with label "H"(historical) shows that Fault is intermittent caused by poor contact in the part's and/or SRSCM connector or was repaired and SRSCM memory was not cleared. Thoroughly check shorting bar/shorting bar release pin and connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or damage. ▶ Repair or replace as necessary and then go to "Verification of Vehicle Repair" procedure.

Terminal and Connector Inspection

1.	Many malfunctions in the electrical system are caused by poor harness and terminals. Faults can also be caused by interference from other electrical systems, and mechanical or chemical damage.

2.	Thoroughly check shorting connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or damage.

3.	Has a problem been found? ▶ Repair as necessary and then go to "Verification of Vehicle Repair" procedure. ▶ Go to "Telltale lamp Circuit Inspection" procedure.

Telltale lamp Circuit Inspection

1.	Ignition "OFF".

2.	Disconnect the battery (-) terminal cable from the battery and wait at least one minutes.

3.	Disconnect SRSCM main harness connector.

4.	Connect the battery (-) terminal cable to the battery and Inginion "ON" & Engine "OFF"

5.	Measure voltage between Telltale lamp terminal of the cluster harness connector and chassis ground. ■ Specification : Batt Voltage

6.

Is the measured voltage within specifications? ▶ Check warning lamp and connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or damage. Repair or replace as necessary and then go to "Verification of Vehicle Repair" procedure. ▶ Check airbag fuse, passenger compartment junction block, harness between junction block and SRS . Repair as necessary and go to "Verification of Vehicle Repair" procedure.
