Hopefully this will help you out;
airbag code 16 indicates a passenger seat weight sensor CAN fault. This means there's a communication issue with the sensor that detects if someone is sitting in the passenger seat. The CAN (Controller Area Network) is a communication bus that various modules in the car use to talk to each other, and the fault code suggests a problem with the signal from the passenger seat weight sensor being transmitted over the CAN.
Here's a more detailed explanation:
Passenger Seat Weight Sensor:
This sensor is located under the passenger seat cushion and is designed to detect the weight of a person sitting there.
CAN Fault:
The CAN bus is a communication network that allows different modules in the car to exchange data. If the passenger seat weight sensor is not communicating properly with the other modules (like the airbag control module) via the CAN, it will trigger code 16.
Possible Causes:
Faulty weight sensor under the seat.
Wiring or connection issues in the passenger seat weight sensor circuit.
A problem with the CAN bus itself (less likely).
Faulty passenger airbag module.
