What Does U0413 Mean?
The vehicle control system is receiving invalid or corrupted data from battery energy control module B via the communication network. This code applies to vehicles with dual battery management systems or split battery packs.
Safety Warning
May result in battery system shutdown, reduced power, or inability to charge. Vehicle should not be operated until diagnosed due to high-voltage safety concerns and potential stranding risk.
Common Causes
35%
Battery energy control module B internal failure or software corruption
30%
CAN bus or network communication circuit fault to battery control module B
20%
Battery pack B cell voltage or temperature sensors providing invalid data
10%
Power supply or ground connection issue at battery energy control module B
5%
Secondary battery pack internal fault affecting module data processing
Diagnostic Steps
1
Step 1: Monitor battery energy control module B data stream to identify which parameters are invalid or showing implausible values
2
Step 2: Verify all cell voltages and temperatures from battery pack B are reading correctly and within expected ranges
3
Step 3: Check voltage supply and ground integrity at battery energy control module B; ensure proper power distribution
4
Step 4: Inspect network wiring between main vehicle controller and battery energy control module B; verify connector pins and shielding integrity
5
Step 5: Check for technical service bulletins and available software updates; replace battery energy control module B if all circuits verify properly
Estimated Repair Cost
$300 - $2,500
Parts + labor, varies by vehicle and location
The vehicle control system is receiving invalid or corrupted data from battery energy control module B via the communication network. This code applies to vehicles with dual battery management systems or split battery packs.
The most common cause of U0413 (Invalid Data Received From Battery Energy Control Module B) is: Battery energy control module B internal failure or software corruption
Typical repair costs for U0413 range from $300 to $2,500, depending on the vehicle, location, and whether you do it yourself or go to a shop.
May result in battery system shutdown, reduced power, or inability to charge. Vehicle should not be operated until diagnosed due to high-voltage safety concerns and potential stranding risk.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to U0413 to identify the root cause.
