What Does U0485 Mean?
The receiving control module is detecting corrupted or out-of-range data from the Radio/Infotainment module on the vehicle communication network. This indicates the radio is transmitting invalid information to other vehicle systems.
Common Causes
30%
Faulty radio/infotainment module with internal processor or memory failure
25%
Damaged or corroded wiring and connectors between radio and CAN bus network
20%
Software glitch or corrupted firmware in radio module requiring update
15%
Poor ground connection or inadequate power supply at radio module
10%
Aftermarket radio installation or modification causing network communication issues
Diagnostic Steps
1
Step 1: Verify proper battery voltage and check power and ground connections at radio module
2
Step 2: Inspect radio connector and antenna connections for corrosion, damage, or loose pins
3
Step 3: Monitor radio module data parameters on scan tool to identify which transmitted values are invalid
4
Step 4: Check for available radio software updates or technical service bulletins related to communication issues
5
Step 5: Perform radio module reset/initialization; replace radio module if invalid data transmission continues
Estimated Repair Cost

Parts + labor, varies by vehicle and location
The receiving control module is detecting corrupted or out-of-range data from the Radio/Infotainment module on the vehicle communication network. This indicates the radio is transmitting invalid information to other vehicle systems.
The most common cause of U0485 (Invalid Data Received From Radio) is: Faulty radio/infotainment module with internal processor or memory failure
Typical repair costs for U0485 range from $150 to $1,200, depending on the vehicle, location, and whether you do it yourself or go to a shop.
While radio malfunction is primarily a comfort issue, invalid data can interfere with other vehicle systems sharing the network. Backup camera, voice commands, or phone integration may be affected, potentially impacting driver awareness.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to U0485 to identify the root cause.
