• U0121
This code means that one of the computers in the car is having trouble talking to another computer. It's like when your phone can't connect to the internet.
U0498 is a communication error between control modules in the vehicle.
U0498 indicates a communication error on the Controller Area Network (CAN) bus, which is used for communication between various control modules in the vehicle. This error suggests that a control module is sending data that is not understood by another module.
• Check for other codes that might indicate specific module failures.
• Inspect the wiring and connectors on the CAN bus for damage or disconnection.
• Use a scan tool to attempt communication with all control modules.
• Repair or replace damaged wiring or connectors.
• Reprogram or replace the faulty control module.
• Clear the codes and test drive to ensure the issue is resolved.

Communication Error
• If the vehicle is under warranty, take it to the dealership.
• Avoid driving the vehicle if critical systems are affected.
Check with your vehicle manufacturer for warranty coverage on control modules.
Communication errors like U0498 have become more common as vehicles have become more reliant on complex electronic systems.
Moderate – While the vehicle may still be operable, unresolved communication issues can lead to further complications.
Driving with unresolved communication issues may affect vehicle safety systems. Always address these issues promptly.
• Vehicle stationary with ignition on
• Engine running and vehicle in motion
The CAN bus wiring is typically located throughout the vehicle, connecting various control modules.
Q: Can I drive my car with a U0498 code?
A: It's best to have it checked as soon as possible, as communication issues can affect critical vehicle systems.
Q: Will a U0498 code clear itself?
A: The code may clear if the issue is intermittent, but it's important to diagnose and fix the underlying problem.
