B1046 on Jeep
Occupant Classification / Restraint Sensor Circuit Fault
B1046 on Jeep vehicles indicates occupant classification / restraint sensor circuit fault. Au7o has documented this code across 1 Jeep model — most commonly on Grand Wagoneer. B1046 is a manufacturer-specific body code most commonly associated with the supplemental restraint (airbag) system, typically a fault in the occupant classification system (passenger seat weight/presence sensing) or a related restraint sensor unit. The airbag control module has detected a sensor or circuit reading outside its expected range. Because this is a safety-restraint code, the airbag warning light is usually on and passenger airbag deployment behavior may be affected. Exact meaning varies by maker, so confirm with vehicle-specific data. Typical repair costs on Jeep range from $350 to $1,400, depending on the specific model and root cause.
Common Causes of B1046
- •Faulty passenger seat occupant weight/classification sensor
- •Damaged wiring or connector under the seat
- •Faulty airbag/restraint control (sensor) module
- •Aftermarket seat covers or items affecting seat sensing
- •Loose or corroded connector at the seat harness
- •System needs recalibration after seat or sensor service

Jeep Grand Wagoneer(1 issue)
- Tailgate Power Cinch Latch Failure / Tailgate Won't Latch or Open2021-2024
The Grand Wagoneer's power cinch tailgate latch mechanism, which uses an electric motor to fully close and seal the rear liftgate, has been reported to fail in both directions — either not cinching closed or not releasing when the open button is pressed. The electric cinch latch assembly can develop motor failures or the latch pawl can bind, leaving owners unable to open or securely close the tailgate. Multiple NHTSA complaints reference the tailgate appearing closed but unlatching while driving.
