B1B0D on Jeep by model: symptoms, diagnosis and fix
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.
Common Symptoms
- airbag warning light on
- service airbag system message
- restraint system warning chime
- intermittent warning after moving seats
- warning returns after clearing codes
How to Fix
Scan the Occupant Restraint Controller for stored codes, then inspect under-seat connectors, terminal tension, harness routing, and any signs of pin drag or intermittent contact. Repairs typically involve connector replacement, terminal repair, harness retention updates, or module/software updates depending on the exact fault. Clearing the light without fixing the root cause usually results in repeat warnings.
Owner tips & cautions
- TipOwners often suggest documenting exactly when the warning appears, especially after seat movement or folding the second row, to help isolate an intermittent connector issue.
- TipAvoid probing SRS connectors with generic test lights; use proper scan diagnostics and battery disconnect procedures before any seat harness inspection.
