What Dodge airbag codes mean

What Dodge calls the module and where it lives

Dodge, Chrysler, Jeep and Ram all run the same computer, the Occupant Restraint Controller, or ORC. Inside the housing are a microprocessor, an electronic impact sensor, an electronic safing sensor, and an energy storage capacitor, and Mopar says the internal sensors are calibrated to the specific vehicle and only serviced with the module.

On the LX cars, Charger and Challenger and 300, factory text puts the ORC on the transmission tunnel near the dash panel beneath the instrument panel center support. Grand Caravan sits it just behind the front seat crossmember under the center console. Every ORC has an orientation arrow on its top label that has to point toward the front of the vehicle. Model coverage lives on our Dodge airbag service page.

How Dodge airbag codes are organized

The B1B block is where the firing circuits live, and Mopar groups each one into four consecutive codes in the same order every time: circuit low, circuit high, circuit open, circuit shorted together. So B1B02 is driver airbag squib 1 open and B1B03 is that same squib shorted together. B1B04 through B1B07 repeat it for driver squib 2, B1B08 through B1B0B for passenger squib 1, and so on through the block.

• B1B00 to B1B0F: driver and passenger frontal squibs, stage 1 and stage 2.
• B1B70 and up: satellite acceleration sensors.
• B1B79 to B1BBD: occupant classification, seat weight sensors, calibration state.
• B1C27 to B1C4F: seat thorax squibs, retractor pretensioners, buckle tensioners.
• B2207 to B2212: ORC and occupant classification module internal faults.
• B2722 and the B22xx configuration codes: module identity and setup state.

Only one code on a Dodge is the crash record. B1BC7, deployment data record full, sets when the ORC's deployment register fills, and factory text calls for the controller to be replaced. After a real deployment you will see circuit open codes in the B1B block sitting alongside it, because the fired inflators now read open. Those are a symptom of the deployment, not four new wiring faults. One block that is not restraint at all: B2100 through B2119 are FCA body and security codes, and they get published as airbag codes on aggregator sites constantly.

Scan tool notes for Dodge

Generic OBD2 covers emissions data on the powertrain and nothing else, so a basic reader will not show a B1B code. Reading them takes a scanner with FCA coverage, and the factory tool is wiTECH.

B1BC7 latches. Reset shops report that a tool attempting to erase it answers cannot execute the routine, and the factory remedy is stated as replacing the controller. Two other things a tool cannot do for you: Mopar says the ORC cannot be repaired or adjusted, and if one gets dropped during service it has to be scrapped rather than reinstalled.

A replacement ORC does not need flash programming, which surprises people. It needs initialization. Mopar ships service controllers in a state that inhibits every squib circuit, described as ORC unlocked, so a new module arrives with B2722 already active and a scan tool has to run module initialization from the miscellaneous menu to lock it. A module out of a different vehicle can also want a vehicle configuration restore, since B222A vehicle line mismatch and B223B vehicle configuration mismatch set when the ORC and the car disagree.

What we see on Dodge vehicles

The Grand Caravan has a genuinely alarming documented fault worth knowing about. NHTSA recall 17V376000 covers 2011 and 2012 Grand Caravans where the driver frontal airbag may deploy on its own if the airbag wiring harness chafes inside the steering wheel. That is the same steering column area that sets driver squib codes when it wears through rather than shorting.

Durango has its own ORC history: 12V391000 covered 2013 Durangos built with the wrong ORC entirely, and 14V643000 covered a 2014 Durango and Grand Cherokee ORC fault that disabled the frontal airbags, the pretensioners and the side airbags. On the Charger and Challenger, the ORC installation procedure spends its warnings on connector latches, and Mopar's own intermittent fault routine is a wiggle test on the harness plus rotating the steering wheel lock to lock if the code is on a driver circuit.
