Wiring Diagram For Seat Weight sensor
Chrysler Town & Country
The occupant classification module (OCM) is the module that monitors the weight in the passenger seat.
Inside the right front seat there is a bladder type weight sensor that weighs the passenger and the OCM device determines how hard the airbag should be deployed. If the light is coming on it's because the sensor is reporting a weight in the seat under 100 pounds or there is a fault code setting.
I suggest get the module scanned to retrieve error codes stored.
But if there are no codes stored in the module and no weight is being put in the seat at the times the light is on then either the faulty OCM or the weight sensor could be bad, more likely it would be the sensor.
