B1B02 on Jeep
Driver Airbag Squib 1 Circuit Open (manufacturer-specific)
B1B02 on Jeep vehicles indicates driver airbag squib 1 circuit open (manufacturer-specific). Au7o has documented this code across 2 Jeep models — most commonly on Grand Cherokee, Wrangler. B1B02 is a manufacturer-specific body (B) code used notably by Chrysler/Dodge to indicate an open circuit in the driver airbag squib (the igniter that deploys the airbag). The restraints control module continuously monitors this circuit, and an open means the driver airbag may not fire in a crash. The airbag warning light is typically on. This is safety-critical and is usually caused by a wiring, clockspring, or connector fault. Confirm against the specific vehicle's service data, as B-code meanings vary by maker. Typical repair costs on Jeep range from $150 to $1,200, depending on the specific model and root cause.
Common Causes of B1B02
- •Faulty clockspring (steering column connection)
- •Open or damaged wiring in the driver airbag circuit
- •Poor or corroded connector at the airbag
- •Faulty driver airbag module
- •Faulty restraints/occupant control module
- •Disturbed connector after steering or airbag service
B1B02 on Jeep by Model
Jeep Grand Cherokee(1 issue)
- Second-Row Seat Side Airbag Connector/Occupant Restraint Fault Warnings2022-2024
Owners of WL-generation Grand Cherokee models have reported persistent airbag warning lights and restraint system messages tied to seat wiring/connectors, especially around second-row or seat-mounted side airbag circuits. FCA also issued safety actions/TSB guidance on certain restraint-related faults in this generation. The practical problem is that the SRS may be disabled or operate improperly until the connector, harness, or module issue is corrected.
Jeep Wrangler(1 issue)
- Clock Spring Failure Causing Airbag Light, Horn, and Cruise Control Loss2000-2006
A common TJ/LJ Wrangler failure is the steering column clock spring wearing out internally, which breaks electrical continuity to the driver airbag, horn, and cruise-control switches. Owners typically report an illuminated airbag light along with an inoperative horn and cruise control. This was widespread enough to generate many owner complaints and a Jeep recall campaign on certain vehicles.
