Passenger Airbag Indicator Disabled

Variant 1

System

Occupant Detect

Symptom

Passenger Airbag Indicator Disabled

Diagnosis & fix steps

LOGIC: Occupant Detection System (ODS) Control Module Requesting Malfunction. ACTION: Scan Occupant Detection Module as an independent sub-controller. Verify seat track load cell calibration; check for objects wedged underneath passenger seat frame.

Red Seal field insights

Mechanical Bind: Heavy debris wedged under the seat frame wedges the four corner strain-gauge load cells, skewing weight measurements and flagging fault status to the main SRS ECU.

Variant 2

System

Safety Restraints (SRS)

Symptom

Airbag Warning / Seat Weight Fault

Diagnosis & fix steps

LOGIC: Occupant Classification System (OCS) Sensor Circuit Range/Performance. ACTION: Clear debris from underneath the passenger seat rails. Perform a zero-point OCS bladder sensor weight recalibration routine using a diagnostic tool.

Red Seal field insights

Correlation Math: The seat weight sensor detects an static weight offset that conflicts with initial factory empty-bench baseline tracking parameters.
