B1B0E is set when the occupant restraint controller cannot get a good resistance reading from the passenger airbag squib 2 circuit. Squib 2 is the second stage of the passenger bag, the one that only comes in on a hard hit. Everything about the repair happens in the wiring or the bag.
Chrysler dual stage passenger airbags carry two initiators, and the ORC checks each one separately. Squib 2 rides on its own pair of wires, (R62) passenger squib 2 line 2 and (R64) passenger squib 2 line 1, and the module reads their resistance with the ignition on.
B1B0E, spelled out in the manual as PASSENGER AIRBAG SQUIB 2 CIRCUIT OPEN, sets when that pair reads open or high. The stage 1 pair can pass its check at the same moment, which is why a scan can show B1B0E by itself with no other airbag code alongside it.
When B1B0E and B1B0A both show up, the whole passenger connector is usually the issue. When B1B0E stands alone, the fault is confined to the stage 2 pins or the two wires behind them, and that narrows the search considerably.
Circuit fault. The ORC is reading resistance in real time and reporting what it finds, so B1B0E is not a stored record of anything and it does not lock the module. Repair the path and the code goes away on the next self test.
No. A reset restores modules that are holding crash data, and B1B0E is an open electrical path. Nothing in the module's memory has to change for this light to go out.
Work the connector and the harness first. If the passenger bag has a failed second initiator, we carry genuine OEM passenger airbags matched by year and model, and we can help you confirm you are ordering a dual stage bag rather than a single stage one. If the vehicle was damaged and the control module is also holding a deployment record, that is separate work that follows the circuit repair.
B1B0E belongs to the Chrysler, Dodge, Jeep, and Ram vehicles built around an ORC, roughly the 2006 to 2015 range. It is documented in the 2007 Jeep Grand Cherokee manual and carries forward through the Dodge Journey, Dodge Durango, and Chrysler 200. Later FCA vehicles report a passenger stage 2 problem as B0011 instead. Numbers in the B1B block are reused by other manufacturers for entirely different systems, so the make has to be right before this definition applies.
Get the glovebox out and put a load tool on the passenger airbag connector. If B1B0E clears with the tool connected, the bag is the failure. If it stays active, measure the (R62) and (R64) wires back to the ORC connector, looking for resistance above one ohm. Check the cowl area for water intrusion while you are in there, since corrosion on those pins is common on older vehicles.
