What Does U0411 Mean?
The vehicle control system is receiving invalid or corrupted data from the electric drive motor control module over the communication network. This code is specific to electric or hybrid vehicles with electric propulsion systems.
Safety Warning
May result in loss of electric propulsion, sudden power loss, or inability to drive. Vehicle should not be operated until diagnosed and repaired due to potential safety risk.
Common Causes
35%
Drive motor control module (inverter) internal fault or software corruption
30%
CAN bus communication fault between hybrid control module and motor controller
20%
Motor position sensor or resolver providing invalid data
10%
High voltage system issues affecting motor controller operation
5%
Poor ground or power supply at motor control module
Diagnostic Steps
1
Step 1: Monitor drive motor control module live data to identify which parameters are showing invalid values or communication errors
2
Step 2: Check high voltage system status and isolation; verify high voltage battery is operating within normal parameters
3
Step 3: Inspect all network communication wiring between hybrid control module and drive motor controller; verify shielding integrity on high-voltage vehicle networks
4
Step 4: Test motor position sensor/resolver signals for proper waveform and continuity; verify sensor power supply voltage
5
Step 5: Check for manufacturer technical service bulletins and software updates; replace drive motor control module if all circuits test properly
Estimated Repair Cost
$300 - $3,500
Parts + labor, varies by vehicle and location
The vehicle control system is receiving invalid or corrupted data from the electric drive motor control module over the communication network. This code is specific to electric or hybrid vehicles with electric propulsion systems.
The most common cause of U0411 (Invalid Data Received From Drive Motor Control Module) is: Drive motor control module (inverter) internal fault or software corruption
Typical repair costs for U0411 range from $300 to $3,500, depending on the vehicle, location, and whether you do it yourself or go to a shop.
May result in loss of electric propulsion, sudden power loss, or inability to drive. Vehicle should not be operated until diagnosed and repaired due to potential safety risk.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to U0411 to identify the root cause.
