B1B0F-PASSENGER AIRBAG SQUIB 2 CIRCUIT SHORTED TOGETHER
2010 Jeep Truck Grand Cherokee SRT-8 V8-6.1L Page 94
Theory of Operation
When powered, the Occupant Restraint Controller (ORC) sends a test current to the squibs to verify the integrity of the squib and wiring. These
circuits are maintained in a "floating" configuration at the module (connected to neither power nor ground) as protection against inadvertent
deployment. Use of the SRS Load Tool Kit 8443A in the tests below substitutes a suspect squib with a known good component. The use of the SRS
Load Tool Adapter provides a test point as well as a method for opening the shorting bar connections within the harness connector.
- When Monitored:
With the ignition on, the Occupant Restraint Controller (ORC) monitors the resistance of the Passenger Squib 2 circuits.
- Set Condition:
The ORC has detected low resistance between the Passenger Squib 2 circuits.

Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding. See: Restraints and Safety Systems/Testing and
Inspection/Initial Inspection and Diagnostic Overview/Restraints System Pre-Diagnostic Procedure.
1. DETERMINE ACTIVE OR STORED DTC
NOTE: Make sure the battery is fully charged.
NOTE: The scan tool, SRS Airbag Load Tool MRL 8443A, and DVOM are required to perform the following test.
1. Select Active or Stored DTC.
Is the DTC active or stored?
ORC - ACTIVE DTC
- Go To 2
ORC - STORED DTC
- Perform the RESTRAINTS SYSTEM INTERMITTENT TEST. . See: Restraints and Safety Systems/Testing and Inspection/Initial
Inspection and Diagnostic Overview/Restraints System Intermittent Condition Test
2. CHECK FOR SHORTED SQUIB CIRCUITS IN PASSENGER AIRBAG
WARNING: Turn the ignition off disconnect the 12-volt battery and wait two minutes before proceeding. Failure to follow these
instructions may result in possible serious or fatal injury.
1. Disconnect the Passenger Airbag Squib connector.
WARNING: Do not place an intact non-deployed airbag face down on a hard surface, the airbag propels into the air if accidentally
deployed. Failure to follow these instructions may result in possible serious or fatal injury.
NOTE: Check the connectors - Clean and repair as necessary.

2. Connect the SRS Load Tool Kit 8443A and SRS Load Tool Jumper 8443-14 to the Passenger Airbag Squib connector.
WARNING: Turn the ignition on, then reconnect the 12-volt battery and wait two minutes before proceeding. Failure to follow these
instructions may result in possible serious or fatal injury.
3. With the scan tool, read the active ORC DTCs.
Does the scan tool display: B1B0F-PASSENGER AIRBAG SQUIB 2 CIRCUIT SHORTED TOGETHER?
Yes
- Go To 3
No
- Replace the Passenger Airbag.
- Perform the ORC VERIFICATION TEST. See: Verification Tests/Occupant Restraint Controller (ORC) Verification Test.
3. CHECK (R64) PASSENGER SQUIB 2 LINE 1 CIRCUIT FOR A SHORT TO (R62) PASSENGER SQUIB 2 LINE 2 CIRCUIT
WARNING: Turn the ignition off disconnect the 12-volt battery and wait two minutes before proceeding. Failure to follow these
instructions may result in possible serious or fatal injury.
1. Disconnect the SRS Load Tool Kit 8443A and SRS Load Tool Jumper 8443-14 to the Passenger Airbag Squib connector.
2. Disconnect the ORC connectors.
NOTE: Check the connectors - Clean and repair as necessary.
3. Connect the SRS Load Tool Adaptor 8443-24 to the ORC C2 connector.
4. Measure the resistance between the (R64) Passenger Squib 2 Line 1 circuit and the (R62) Passenger Squib 2 Line 2 circuit at the SRS Load
Tool Adaptor 8443-24.
Is the resistance below 10K Ohms?
Yes
- Repair the (R64) Passenger Squib 2 Line 1 circuit for a short to the (R62) Passenger Squib 2 Line 2 circuit.
- Perform the ORC VERIFICATION TEST. See: Verification Tests/Occupant Restraint Controller (ORC) Verification Test.
No
- WARNING: If the Occupant Restraint Controller (ORC) is dropped at any time, it must be replaced. Failure to follow these
instructions may result in possible serious or fatal injury.
- Replace the ORC.
- Perform the ORC VERIFICATION TEST. See: Verification Tests/Occupant Restraint Controller (ORC) Verification Test.
