B1B00 on Jeep by model: symptoms, diagnosis and fix
FCA bulletin 08-005-17 REV. A covers an airbag or traction-control warning light on 2011-2016 JK Wranglers caused by the steering-column clockspring, with driver-airbag circuit, steering-angle-sensor, speed-control switch or steering-wheel control codes stored. A failed clockspring can leave the driver airbag circuit open. It applies to 2011-2016 Jeep Wrangler and Wrangler Unlimited (JK) left-hand-drive models built on or after February 16, 2010 and before May 2, 2016, when one of the bulletin's trouble codes is stored. A 2016 built on or after May 2, 2016 is outside the bulletin. Right-hand-drive JKs were covered instead by safety recalls S40 (NHTSA 16V-288, built through May 2, 2016) and 27B (NHTSA 24V-196, 2016 models built May 3 to September 16, 2016).
Common Symptoms
- Airbag warning light on
- Traction-control warning light on
- Cruise control not working
- Steering-wheel controls not working
How to Fix
If the airbag light is on, have a dealer read the codes; the bulletin applies only when one of its codes is found. The repair replaces the clockspring, the upper and lower steering-column shrouds and the steering-wheel back cover. The bulletin notes a 15-year, unlimited-mile warranty for this repair on included vehicles, counted from the in-service date; the dealer must confirm that your VIN is included. This is not a recall. Do not work on the airbag yourself.

Frequently asked questions
What does B1B00 mean on a Jeep?
B1B00 stands for "Driver Airbag Squib 1 Circuit Low." The Occupant Restraint Controller (ORC / airbag control module) continuously measures the resistance of the driver frontal airbag squib 1 (initiator) circuit. B1B00 sets when that measured resistance falls below the specified window, indicating one or both squib 1 lines are shorted to ground or to each other rather than presenting the normal initiator resistance. The ORC disables airbag deployment on that circuit and illuminates the airbag warning lamp. On Jeep it is documented across 1 model: Wrangler.
What are the most common causes of B1B00?
The most common causes of B1B00 are: Driver squib 1 line 1 or line 2 circuit shorted to ground, Chafed or pinched clockspring ribbon in the steering column, Failed clockspring assembly, Faulty driver frontal airbag module (inflator initiator), Damaged or corroded connector at the steering wheel or ORC, Failed Occupant Restraint Controller.
