u010c lost communication with turbocharger supercharger control module a

OBD2 Code: U010C

Description: Lost Communication With Turbocharger/Supercharger Control Module A

Definition: This code indicates that the vehicle’s main computer (PCM) has lost communication with the turbocharger/supercharger control module. The PCM uses this communication to monitor and control the performance of the turbo or supercharger system.

Typical Severity: Critical

Common Causes

Common causes of the OBD2 code u010c include:

• Defective turbocharger/supercharger control module
• Wiring issues such as damaged wires or poor connections
• Faulty powertrain control module (PCM)
• Interference from other electronic devices

 

Common Misdiagnosis

• Check for any other stored codes that might indicate a related issue.
• Inspect the wiring and connectors between the Engine Control Module (ECM) and the Turbocharger/Supercharger Control Module for damage or corrosion.
• Verify that the Turbocharger/Supercharger Control Module is receiving power and ground signals.
• Test the communication lines (CAN bus) for continuity and proper voltage levels.
• If equipped, use a scan tool to check for module-specific fault codes in the Turbocharger/Supercharger Control Module.
• Perform a visual inspection of the turbo/supercharger system components for obvious signs of failure or disconnection.
• If necessary, update or reprogram the ECM software to ensure compatibility with all modules.
• If all else fails, consider replacing the Turbocharger/Supercharger Control Module after confirming it is faulty through testing procedures.
