B1B05-DRIVER AIRBAG SQUIB 2 CIRCUIT HIGH
2010 Jeep Truck Grand Cherokee SRT-8 V8-6.1L Page 121
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 Adaptor 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 voltage on the Driver Squib 2 circuits.
- Set Condition:
The ORC has detected voltage on the Driver Squib 2 circuits.

instructions may result in possible serious or fatal injury.
4. Measure the voltage of the (R63) Driver Squib 2 Line 1 circuit between the Clockspring connector and ground.
5. Measure the voltage of the (R61) Driver Squib 2 Line 2 circuit between the Clockspring connector and ground.
Is there any voltage present for either measurement?
Yes
- Repair the Driver Squib 2 circuit(s) for a short to Battery.
- Perform the ORC VERIFICATION TEST. See: Verification Tests/Occupant Restraint Controller (ORC) Verification Test.
No
- 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.
- 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.
