What Does U055E Mean?
Invalid data is being received from Front Controls Interface Module B on the vehicle network. This module typically handles secondary front-mounted controls, switches, or interface functions, with the exact application varying by manufacturer.
Common Causes
35%
Failed front controls interface module B requiring replacement
30%
Damaged wiring or corroded connectors at front controls module
20%
CAN bus communication network faults or signal interference
10%
Module software issues or programming corruption
5%
Power supply circuit problems or intermittent voltage
Diagnostic Steps
1
Step 1: Identify the specific front controls handled by Interface Module B using service documentation (may include climate controls, audio controls, or other front-mounted switches)
2
Step 2: Monitor live scan tool data from the module to determine which control inputs or outputs are transmitting invalid data
3
Step 3: Inspect all wiring and connectors to the front controls interface module; check for water intrusion, corrosion, or physical damage common in front panel areas
4
Step 4: Verify CAN bus network integrity at module location; test for proper termination resistance and clean signal patterns
5
Step 5: Perform module reprogramming if available; test with known-good module if possible; replace module if fault is confirmed internal
Estimated Repair Cost
$150 - $900
Parts + labor, varies by vehicle and location
Invalid data is being received from Front Controls Interface Module B on the vehicle network. This module typically handles secondary front-mounted controls, switches, or interface functions, with the exact application varying by manufacturer.
The most common cause of U055E (Invalid Data Received From Front Controls Interface Module "B") is: Failed front controls interface module B requiring replacement
Typical repair costs for U055E range from $150 to $900, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Generally minor safety impact as this typically affects convenience controls. However, if module controls critical functions like defrost or climate systems, it could indirectly affect driver visibility or comfort during operation.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to U055E to identify the root cause.
