What Jeep airbag codes mean

What Jeep calls the module and where it lives

Jeep runs the corporate Mopar computer, the Occupant Restraint Controller. Inside are a microprocessor, an electronic impact sensor, an electronic safing sensor, an energy storage capacitor, and the rollover sensor. That last one is the detail that catches people out. The rollover sensor is not a separate part you can replace, and Mopar warns that an ORC accidentally rolled during service while still connected to battery power will fire the side curtains.

On the Wrangler JK, factory text secures the ORC with four nuts to a bracket welded to the transmission tunnel between the front seats, under the console and behind the shifter. The Grand Cherokee uses three screws next to the park brake mechanism. Compass and Patriot move it forward of the shifter near the dash panel. Coverage is on our Jeep airbag service page.

How Jeep airbag codes are organized

Mopar assigns four consecutive numbers to every firing circuit, in a fixed order: circuit low, circuit high, circuit open, circuit shorted together. Learn the pattern once and any B1B code decodes itself. B1B01 is driver squib 1 reading high, B1B02 is that circuit open, B1B03 is it shorted to itself.

• B1B00 to B1B0F: driver and passenger frontal squibs.
• B1B10 to B1B1A: knee bolster and side curtain squibs.
• B1B70 to B1B75: up-front and side satellite acceleration sensors.
• B1B8D to B1B95: driver and passenger seat track position sensors.
• B1C27 to B1C47: seat thorax squibs and retractor pretensioners.
• B2207 to B220D: ORC internal faults and its two accelerometers.

The crash record on a Jeep is a single code, B1BC7 deployment data record full, and factory text says replace the controller. Everything else in the list is either a live circuit measurement or the module reporting on itself. After a rollover or a side hit you will see curtain squib circuits reading open next to B1BC7, which is the fired hardware, not fresh wiring damage. The B2100 through B2119 block that shows up on some code sites as Jeep airbag codes is body and security, not restraints.

Scan tool notes for Jeep

A generic OBD2 reader will not show a B1B code. Reading Jeep restraint codes takes a scanner with FCA coverage, and wiTECH is the factory tool. On 2018 and newer Jeeps there is a second wall: the Security Gateway module allows reading codes but blocks erasing them, blocks resets and relearns and calibrations, and blocks special functions, unless the tool authenticates through an AutoAuth account. So a shop can tell you what your Wrangler's code is and still not be able to clear it.

B1BC7 latches. Reset shops report a tool attempting to erase it answers cannot execute the routine, and the factory remedy is stated as controller replacement. A service ORC ships unlocked with every squib circuit inhibited and arrives with B2722 active until a scan tool runs module initialization.

Mopar's own routine for an intermittent airbag light is worth copying: inspect the harness and connectors for chafed, pierced or pinched wire and bent, spread or corroded terminals, wiggle the harness for the circuit the code names, and if it is a driver circuit, rotate the steering wheel stop to stop while watching. That last step is factory-endorsed clockspring diagnosis.

What we see on Jeep vehicles

Wrangler clocksprings are the story. NHTSA recall 16V290000 covers 2007 to 2010 JK Wranglers where the clockspring assembly can be contaminated with dust and cause the airbag circuit to fail. 16V288000 covers right hand drive 2011 to 2016 Wranglers for the same mode, and 24V196000 covers 2016 right hand drive units where debris contamination can keep the driver airbag from deploying. Owners routinely report the pairing directly: airbag light cycling on and off with a chime, code B1B02, clockspring test failed.

Beyond the column, 16V734000 covered 2016 and 2017 Wranglers where front impact sensor wiring could detach before the signal reached the ORC. Grand Cherokee has ORC recall history of its own, from 14V643000 in 2014 through a 2026 campaign covering 2022 and newer Grand Cherokee and Grand Cherokee L for an ORC software error that delayed side airbag deployment. A VIN check is cheap before anyone condemns a module.
