B0083 indicates a fault in the deployment control circuit for the load limiter on the second-row left seat belt. This safety feature manages belt tension during a collision to reduce occupant injury. The Supplemental Restraint System (SRS) warning light will illuminate to alert the driver.
Seat adjustment mechanisms often chafe or break wires running beneath the cushion.
Electrical connections at the seat belt assembly may oxidize or become disconnected.
The pyrotechnic component within the retractor assembly may have an open circuit.
Prior accident repairs may have left restraint system components damaged or unplugged.
Internal processing failure within the safety restraint controller is rare.
The vehicle is drivable, but the seat belt safety system may not function correctly in a crash.
No, this is an SRS system code; the engine computer (PCM) is not involved, and the SRS module rarely needs replacement.
The code will likely return immediately if the underlying electrical fault is not corrected.
Seat tracks move frequently, causing stress and fatigue on the harnesses routed underneath.
