What Does U010C Mean?
The PCM has lost network communication with the primary turbocharger/supercharger control module. This prevents proper monitoring and control of forced induction boost pressure and wastegate operation.
Common Causes
35%
Turbo/supercharger control module internal failure
30%
Damaged wiring or corroded connectors in module circuit
20%
CAN bus communication circuit fault
10%
Loss of module power supply or ground connection
5%
PCM software issue or module programming error
Diagnostic Steps
1
Step 1: Verify power and ground at turbo/supercharger control module connector using multimeter
2
Step 2: Inspect wiring harness and connectors for heat damage (common near turbocharger due to high temperatures)
3
Step 3: Test CAN bus signals at module connector for proper voltage and waveform
4
Step 4: Check module cooling and mounting location for excessive heat exposure causing module failure
5
Step 5: Scan for additional network codes and test module in isolation if possible
Estimated Repair Cost
$200 - $1,500
Parts + labor, varies by vehicle and location
The PCM has lost network communication with the primary turbocharger/supercharger control module. This prevents proper monitoring and control of forced induction boost pressure and wastegate operation.
The most common cause of U010C (Lost Communication With Turbocharger/Supercharger Control Module "A") is: Turbo/supercharger control module internal failure
Typical repair costs for U010C range from $200 to $1,500, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Vehicle may enter limp mode with reduced power output. Safe to drive with caution but performance will be significantly limited and potential for overboosting exists.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to U010C to identify the root cause.
