What Does U010D Mean?
Network communication has been lost with the secondary turbocharger/supercharger control module B. This code appears in vehicles with twin-turbo or staged boost systems requiring multiple control modules.
Common Causes
35%
Failed turbo/supercharger control module B electronics
30%
Heat-damaged wiring or melted connectors near turbocharger B
20%
CAN network fault affecting module B communication
10%
Power or ground circuit failure specific to module B
5%
Module mounting or cooling system failure causing overheating
Diagnostic Steps
1
Step 1: Check power supply and ground integrity at turbo control module B connector
2
Step 2: Thoroughly inspect for heat damage to wiring, especially near exhaust components and turbocharger B
3
Step 3: Test CAN communication signals at module B and compare with module A for consistency
4
Step 4: Verify module B is properly mounted with adequate heat shielding and cooling
5
Step 5: Test module functionality by swapping with module A if identical and accessible
Estimated Repair Cost
$200 - $1,500
Parts + labor, varies by vehicle and location
Network communication has been lost with the secondary turbocharger/supercharger control module B. This code appears in vehicles with twin-turbo or staged boost systems requiring multiple control modules.
The most common cause of U010D (Lost Communication With Turbocharger/Supercharger Control Module "B") is: Failed turbo/supercharger control module B electronics
Typical repair costs for U010D range from $200 to $1,500, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Performance will be reduced and vehicle may operate in limp mode. Safe to drive but acceleration will be limited and uneven boost delivery may occur.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to U010D to identify the root cause.
