This summary uses the existing diagnostic information shown in full below.
This code means that the car's computer isn't getting a message from the steering wheel controls. It's like when you send a text and it doesn't go through.
The car's computer system uses a network called CAN (Controller Area Network) to communicate. This code indicates that there is no signal from the Switch Cluster on the Steering Column.
The P3220 code is set when the CAN bus system fails to receive a signal from the Switch Cluster Steering Column (SZL). This component is responsible for sending various control signals, such as those for the steering wheel buttons, to the vehicle's central computer.
• Non-functional steering wheel controls
• Warning lights on the dashboard
• Possible loss of certain steering functions
• Faulty Switch Cluster Steering Column (SZL)
• Damaged or corroded wiring/connectors
• Faulty CAN bus network
CAN: Controller Area Network, a vehicle bus standard designed to allow microcontrollers and devices to communicate with each other.
SZL: Switch Cluster Steering Column, a component responsible for the controls on the steering wheel.
• Check for any other related error codes.
• Inspect the wiring and connectors related to the SZL.
• Test the CAN bus network for proper communication.
• Replace the faulty SZL unit.
• Repair or replace damaged wiring/connectors.
• Reset the vehicle's computer system.
• OBD-II scanner
• Multimeter
• CAN bus diagnostic tool

This code has been associated with BMW models due to the complexity of their electronic systems.
Moderate – While the vehicle may still be drivable, it is recommended to address the issue to avoid further complications.
Driving with impaired steering controls can be hazardous. Ensure repairs are made promptly to maintain vehicle safety.
• Vehicle in Park

Q: Can I drive with a P3220 code?
A: While you may be able to drive, it's best to get it checked as steering controls may not function properly.
Q: How do I reset the P3220 code?
A: After repairs, use an OBD-II scanner to clear the code from the vehicle's computer.
