What Does U2011 Mean?
A module on the vehicle's communication network is sending corrupted or incorrect data to other modules. This prevents proper communication between control units, potentially affecting multiple vehicle systems.
Common Causes
35%
Faulty control module with corrupted software or internal failure
30%
Corroded or damaged module connector pins causing signal distortion
20%
Low battery voltage or unstable power supply to modules
15%
Software version mismatch between communicating modules
Diagnostic Steps
1
Step 1: Check battery voltage and charging system; ensure stable 12-14V supply
2
Step 2: Identify which specific module is transmitting invalid data using bi-directional scan tool or network monitoring
3
Step 3: Inspect identified module connector for corrosion, bent pins, or moisture intrusion
4
Step 4: Check for available software updates or TSBs for the affected module
5
Step 5: Monitor live network data to verify proper message format and timing from suspect module
Estimated Repair Cost
$150 - $1,200
Parts + labor, varies by vehicle and location
A module on the vehicle's communication network is sending corrupted or incorrect data to other modules. This prevents proper communication between control units, potentially affecting multiple vehicle systems.
The most common cause of U2011 (Module Transmitted Invalid Data (Non SCP)) is: Faulty control module with corrupted software or internal failure
Typical repair costs for U2011 range from $150 to $1,200, depending on the vehicle, location, and whether you do it yourself or go to a shop.
May cause erratic behavior of multiple vehicle systems including instrument cluster, climate control, or body functions. Generally safe to drive but may experience unpredictable issues.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to U2011 to identify the root cause.
