For a complete wiring diagram Refer to Section 8W.When Monitored:With the ignition on.Set Condition:The Occupant Restraint Controller (ORC) monitors the resistance of the Driver Squib 1 circuits. The ORC will set this DTC if it detects low resistance between the Driver Squib 1 circuits.Possible Causes(R43) DRIVER SQUIB 1 LINE 2 CIRCUIT SHORTED TO (R45) DRIVER SQUIB 1 LINE 1 CIRCUITSTEERING CONTROL MODULE (SCM)DRIVER AIRBAGOCCUPANT RESTRAINT CONTROLLER (ORC)1. DETERMINE ACTIVE OR STORED DTCEnsure that the battery is fully charged.The scan tool, SRS Airbag Load Tool MRL 8443, and DVOM are required to perform the following test.Turn the ignition on.Select ACTIVE or STORED DTC:ACTIVE DTCGo To 2 STORED DTCGo To 52. CHECK FOR SHORTED SQUIB CIRCUITS IN DRIVER AIRBAG

To avoid serious or fatal injury, turn the ignition off, disconnect the battery and wait two minutes before proceeding.To avoid serious or fatal injury, do not place an intact undeployed airbag face down on a hard surface, the airbag will propel into the air if accidentally deployed.Disconnect the Driver Airbag Squib connectors.Check connectors - Clean and repair as necessary.Connect the 8443 Load Tool and 8443-1 Jumper to the Driver Airbag Squib connectors.To avoid serious or fatal injury, turn the ignition on, then reconnect the battery.With the scan tool, read the active ORC DTCs.Does the scan tool display: B1B03-DRIVER AIRBAG SQUIB 1 CIRCUIT SHORTED TOGETHER?YesGo To 3NoTo avoid serious or fatal injury, turn the ignition off, disconnect the battery and wait two minutes before proceeding.Replace the Driver Airbag in accordance with the Service Information.Perform *AIRBAG SYSTEM VERIFICATION TEST - VER 1.3. CHECK STEERING CONTROL MODULE C4 (CLOCKSPRING) SQUIB CIRCUITS FOR A SHORT TOGETHER

To avoid serious or fatal injury, turn the ignition off, disconnect the battery and wait two minutes before proceeding.Disconnect the 8443 Load Tool and Jumper from the Driver Airbag Squib connectors.Disconnect the Steering Control Module C4 connector.Check connectors - Clean and repair as necessary.Connect the 8443 Load Tool and 8443-19 Jumper to the Steering Control Module C4 connector.To avoid serious or fatal injury, turn the ignition on, then reconnect the battery.With the scan tool, read the active ORC DTCs.Does the scan tool display: B1B03-DRIVER AIRBAG SQUIB 1 CIRCUIT SHORTED TOGETHER?YesGo To 4NoTo avoid serious or fatal injury, turn the ignition off, disconnect the battery and wait two minutes before proceeding.Replace the Steering Control Module in accordance with the Service Information.Perform *AIRBAG SYSTEM VERIFICATION TEST - VER 1.4. CHECK (R43) DRIVER SQUIB 1 LINE 2 CIRCUIT FOR A SHORT TO (R45) DRIVER SQUIB 1 LINE 1 CIRCUIT

To avoid serious or fatal injury, turn the ignition off, disconnect the battery and wait two minutes before proceeding.Disconnect the 8443 Load Tool and Jumper from the Steering Control Module connector.Disconnect the ORC connectors.Check connectors - Clean and repair as necessary.Connect the ORC 8443-32-L Adaptor to the ORC connectors.The IP Harness is always connected to the right side (C1) of the 8443-32-L Adapter.Measure the resistance between the (R43) Driver Squib 1 Line 2 circuit and the (R45) Driver Squib 1 Line 1 circuit at the ORC 8443-32-L Adapter cavities C1-9 and C1-10.Is the resistance below 10k ohms?YesRepair the (R43) Driver Squib 1 Line 2 circuit for a short to the (R45) Driver Squib 1 Line 1 circuit.Perform *AIRBAG SYSTEM VERIFICATION TEST - VER 1.NoIf the Occupant Restraint Controller (ORC) is dropped at any time, it must be replaced. Failure to take the proper precautions can result in accidental airbag deployment and serious or fatal injury.Replace the ORC in accordance with Service Information.Perform *AIRBAG SYSTEM VERIFICATION TEST - VER 1.5. CHECKING STORED OR INTERMITTENT CODESDiagnose and repair all active codes before diagnosing stored codes. Refer to the Table of Contents in this Section for a complete list of airbag system diagnostic procedures.With the scan tool, record and erase all Airbag System Module DTCs.To avoid serious or fatal injury, turn the ignition off, disconnect the battery and wait two minutes before proceeding.Using the wiring diagram/schematic as a guide, inspect the related wiring and connectors for chafed, pierced, pinched, and partially broken wires, and for broken, bent, pushed out, corroded, and contaminated terminals. Repair as necessary.Reconnect all disconnected components and harness connectors.To avoid serious or fatal injury, turn the ignition on, then reconnect the battery.With the scan tool, monitor for active codes while performing the following:Wiggle the wiring harness and connectors of the related airbag circuit.Continue the test until either a code becomes active or the problem area is isolated.In the previous steps you have attempted to recreate the conditions responsible for setting the DTC in question / causing the intermittent condition.Are any ACTIVE DTCs present?YesSelect the appropriate diagnostic procedure from the Table of Contents in this section.NoNo problem found at this time. Erase all codes before returning the vehicle to the customer.
