B1B73-LEFT SIDE SATELLITE ACCELERATION SENSOR 2 INTERNAL
2010 Jeep Truck Grand Cherokee SRT-8 V8-6.1L    Page 186
Theory of Operation
The impact sensors perform their own self-test using power supplied by the Occupant Restraint Controller (ORC) then communicates this status back
to the ORC with periodic updates. The repair of this fault condition involves verifying the integrity of the wiring between the ORC and the sensor.
- When Monitored:
The Occupant Restraint Controller (ORC) continuously communicates with the Left Side Impact Sensor 2 over the sensor signal circuit. The
sensor communication and on board diagnostics are powered by the ORC signal.
- Set Condition:
This code will set, if the ORC and the Left Side Impact Sensor 2 do not establish and maintain valid data communications.

B1C3F-1st ROW DRIVER SEAT BELT BUCKLE PRETENSIONER CIRCUIT OPEN
2010 Jeep Truck Grand Cherokee SRT-8 V8-6.1L    Page 218
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 the 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 jumpers and the SRS Load Tool Adapter tool provides a test point, as well as a method for opening the shorting bar connections within
the harness connector.

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.
