What Does U0214 Mean?
The network has lost communication with the Remote Function Actuation module, which handles remote keyless entry, remote start, alarm functions, and other wireless command features. This prevents proper remote operation of vehicle systems.
Common Causes
35%
Faulty remote function actuation module internal failure or antenna circuit issue
30%
Damaged wiring or connector to remote actuation module, often located in overhead console or near antenna
20%
CAN bus or LIN bus communication network fault affecting body systems
10%
Power supply fault including blown fuse or poor ground connection
5%
Module not programmed or configured properly after replacement or battery disconnect
Diagnostic Steps
1
Step 1: Verify all relevant fuses and check battery voltage; confirm good ground connections at module location
2
Step 2: Locate remote function actuation module (typically overhead console, behind dash, or near antenna) and inspect connector for damage or corrosion
3
Step 3: Test scan tool communication directly with remote actuation module to verify if module is responsive
4
Step 4: Check network communication signals (CAN or LIN) at module connector using multimeter or scope
5
Step 5: If power and network signals are present but module doesn't communicate, replace remote function actuation module and reprogram vehicle configuration
