3. Monitor diagnostic trouble code and present of trouble code.
4. Using a scan tool, clear the DTC.






5. Is DTC present problem?

YES
a. Go to "W/Harness Inspection" procedure.

NO
a. 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 connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or damage.
b. 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 connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or damage.
3. Has a problem been found?

YES
a. Repair as necessary and then go to "Verification of Vehicle Repair" procedure.

NO
a. Go to "Component Inspection" procedure.

Component Inspection
1. Ignition "ON" & Engine "OFF" and Using a scan tool, clear the DTC.
2. Ignition "OFF".
3. Disconnect the battery (-) terminal cable from the battery, and wait at least one minute.
4. Disconnect RPSIS connector.
5. Substitute the RPSIS and check for proper operation.
6. Is DTC present problem?

YES
a. Substitute a known-good SRSCM, and check for proper operation. If the problem is corrected, replace SRSCM and then go to "Verification of Vehicle Repair" procedure.
b. Substitute the SRS main harness and check for proper operation. If the problem is corrected, replace SRS main harness and then go to "Verification of Vehicle Repair" procedure.

NO
a. Substitute a known-good RPSIS, and check for proper operation. If the problem is corrected, replace RPSIS and then go to "Verification of Vehicle Repair" procedure.

Verification of Vehicle Repair
After a repair, it is essential to verify that the fault has been corrected.
1. Connect scantool and select "Diagnostic Trouble Codes (DTC)" mode
2. Using a scan tool, clear the DTC.
3. Operate the vehicle within DTC Enable conditions in General information.
4. Are any DTC present?

YES
