Circuit Testing Connector Repairs Testing for Intermittent Conditions and Poor Connections Wiring Repairs Circuit/System Testing 1. With the ignition ON, with a scan tool, request the ignition voltage parameter in the SIR data list. If the parameter does not read 9-16 volts, test the ignition 1 voltage for a short to If a condition exists, make the appropriate repair. 2. With the ignition OFF, test the SDM ground circuit for an open or high resistance. If a condition exists, make the appropriate repair 3. Remove the inflatable restraint SDM connector. Inspect the SDM connector for damage or corrosion that may cause a malfunction. If damage or corrosion is found make the appropriate repair. 4. Replace the SDM. 5. If replacement of the SDM does not repair the vehicle, replace the IPC. Repair Procedures Perform the Diagnostic Repair Verification after completing the diagnostic procedure.
