B1B0A is the occupant restraint controller reporting an open on the passenger airbag squib 1 circuit. It is the passenger side counterpart to the driver squib codes, and the suspect list is different because there is no clockspring in the path. The fix lives in the wiring or the bag.
Squib 1 is the first stage initiator in the passenger airbag. With the ignition on, the ORC on Chrysler, Dodge, Jeep, and Ram vehicles measures the resistance of the passenger squib 1 pair, listed in the service manual as (R42) passenger squib 1 line 2 and (R44) passenger squib 1 line 1. B1B0A sets when that reading comes back open or too high to trust.
The factory wording is PASSENGER AIRBAG SQUIB 1 CIRCUIT OPEN, and the diagnostic starts by putting a load tool on the passenger airbag connector. If the code drops with the tool in place, the bag is the problem. If it stays, the trouble is further back in the harness or at the ORC.
The passenger circuit lives behind the dash and the glovebox instead of inside the steering column, so it never flexes the way the driver loop does. B1B0A is far more often a disturbed connector than a worn one. Dash work, radio and HVAC jobs, glovebox removal, and windshield replacement all put hands near this harness.
Circuit fault. The module is measuring an open right now, on this key cycle, which is why the light comes back immediately after any attempt to clear the code. There is no crash record involved and the module is not locked, so nothing about B1B0A requires the module to leave the vehicle.
No. Erasing memory does not close an open circuit. Repair the connector, the harness, or the bag, and B1B0A clears itself once the ORC gets a good resistance reading back.
Start with the connector, since an unseated plug after dash work costs nothing to fix. If the bag itself is open we stock genuine OEM passenger airbags by year and model. If the vehicle also has stored crash data from an accident, that part is what our airbag module reset handles, and it comes after the circuit is right.
B1B0A is a Chrysler group code, so it appears on Chrysler, Dodge, Jeep, and Ram vehicles that use an ORC, roughly 2006 through the mid 2010s. The Jeep Grand Cherokee, Dodge Journey, Dodge Durango, and Chrysler 200 service manuals all list it. On later FCA platforms the same problem reports as B0010, the generic passenger frontal stage 1 code. Other manufacturers use B1B numbers for unrelated systems such as parking sensors, so check the make before ordering anything.
Pull the glovebox and get eyes on the passenger airbag connector before anything else. Confirm it is fully home with its lock engaged, and look for a terminal that has spread or backed out. If the connector is good, put a load tool on it and see whether the code goes away, since that single test splits the bag from the harness in one step.
B1B0E is the same fault on the passenger second stage, B1B02 is the driver side equivalent, and B0010 is the generic code newer vehicles report instead.
