B1B01 is the occupant restraint controller reporting voltage sitting on the driver airbag squib circuit, where there is supposed to be none. It is a live circuit fault pointing at the driver airbag, the clockspring, or the wiring between them. Clearing the module's memory does not turn this light off.
The squib is the small electrical initiator buried inside the driver airbag. On Chrysler, Dodge, Jeep, and Ram vehicles the occupant restraint controller, or ORC, deliberately holds both squib wires in a floating state, connected to neither power nor ground, so nothing outside the module can fire the bag by accident. With the ignition on, the ORC watches the voltage on those two driver squib 1 lines.
B1B01 sets when the ORC measures voltage where that floating circuit should read nothing. Factory service information spells the code out as DRIVER AIRBAG SQUIB 1 CIRCUIT HIGH, and the set condition is simply that the ORC has detected voltage on the driver squib 1 circuits. Something has tied a line that is supposed to float to a power source.
The Chrysler test walks the circuit backward from the bag toward the module. A load tool goes on the driver airbag connector first, then the clockspring connector, then the ORC connector, where the two driver squib lines get measured for voltage to ground. Whichever step makes the code stop reporting holds the fault.
B1B01 is a circuit fault. The ORC is reporting a voltage it is measuring right now on a live wire, which is why the code comes right back on the next key cycle while the short is still there. Nothing about B1B01 says the vehicle was in an accident, and it does not lock the module the way a stored deployment record does.
No. A reset restores a module that is holding crash data and locked deployment records, and B1B01 is neither. The short to battery has to be found and repaired at the airbag, the clockspring, or the harness before the light goes out. We would rather say that up front than have somebody ship us a module that tests fine.
If the factory test lands on the clockspring or the driver airbag, those are the parts to change, and we stock genuine OEM clocksprings and driver airbags. If the same scan also turns up deployment or crash data codes from an earlier collision, that half is our work: our airbag module reset handles the stored data once the circuit is repaired.
B1B01 in this squib form belongs to the Chrysler group vehicles built around the ORC, which covers Chrysler, Dodge, Jeep, and Ram from the mid 2000s into the mid 2010s. Factory service information carries it on the 2007 and 2010 Jeep Grand Cherokee, the 2009 Dodge Journey, the 2011 Dodge Durango, and the 2013 Chrysler 200. Later platforms such as the 2012 Charger and 300 and the 2013 Grand Cherokee report driver circuit problems under the generic B0001 range instead. Other automakers reuse the B1B number block for systems that have nothing to do with restraints, so confirm the make before you order a part off this code.
Scan the vehicle and note whether B1B01 is active or stored. Active means the fault is present right now and can be chased with a meter. Stored means it came and went, and the factory approach there is to wiggle the airbag harness and turn the steering wheel from stop to stop while watching for the code to reappear. Work the circuit in the order the manual does: driver airbag, clockspring, harness, then module.
Read B1B02 and B1B03 alongside this one, the open and shorted together versions of the same driver squib circuit. B0001 is the generic driver frontal code if your scan tool reports that instead, and B1925 is the Ford version of a short to battery on an airbag loop.
