What Does U0486 Mean?
The control module is receiving corrupted or implausible data from the antenna control module over the vehicle communication network. This typically affects radio reception, GPS, satellite radio, or cellular connectivity depending on the antenna system.
Common Causes
35%
Faulty antenna control module with internal circuit or software corruption
30%
Damaged or corroded wiring harness/connectors between antenna module and network bus
20%
Network communication bus fault (CAN/LIN circuit issues)
10%
Low voltage supply to antenna control module causing data corruption
5%
Software version mismatch or corrupted module programming
Diagnostic Steps
1
Step 1: Monitor live data stream from antenna control module to identify specific invalid parameter
2
Step 2: Check voltage supply and ground circuits to antenna control module (typically 12V and ground)
3
Step 3: Inspect wiring harness and connectors for damage, corrosion, or water intrusion
4
Step 4: Use scan tool to verify network communication integrity and check for network-wide issues
5
Step 5: Replace antenna control module if all circuits test normal and software is up-to-date
Estimated Repair Cost
$150 - $600
Parts + labor, varies by vehicle and location
The control module is receiving corrupted or implausible data from the antenna control module over the vehicle communication network. This typically affects radio reception, GPS, satellite radio, or cellular connectivity depending on the antenna system.
The most common cause of U0486 (Invalid Data Received From Antenna Control Module) is: Faulty antenna control module with internal circuit or software corruption
Typical repair costs for U0486 range from $150 to $600, depending on the vehicle, location, and whether you do it yourself or go to a shop.
No direct safety impact on vehicle operation. Radio, navigation, or satellite services may be degraded or inoperative.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to U0486 to identify the root cause.
