B1B00 on Jeep
Driver Airbag Squib 1 Circuit Low
B1B00 on Jeep vehicles indicates driver airbag squib 1 circuit low. Au7o has documented this code across 1 Jeep model — most commonly on Compass. 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. Typical repair costs on Jeep range from $150 to $600, depending on the specific model and root cause.
Common Causes of B1B00
- •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

Jeep Compass(1 issue)
- Auxiliary Stop/Start Battery Failure Causing Parasitic Drain and No-Start2017-2022
MP Compasses with engine Stop/Start carry a small auxiliary battery in addition to the main battery. When the auxiliary battery degrades - which owners commonly report at 2-4 years - it back-drains the main battery while the vehicle sits, leaving the Compass dead after a few days despite a new main battery, alternator and starter. The first warning is usually the Stop/Start Not Available message or a Stop/Start warning light, followed by intermittent no-crank, flickering dash lights and spurious module faults. Replacing only the main battery is the classic misdiagnosis; the pair must be healthy and both must be registered/relearned so the charging strategy is correct.
