Delphi Paccar ETC-3 PCI Engine Computer – Failure & Repair Options

The engine control computer, also known as the engine controller, engine module, PCI module, or ECU, is a key component managing the operation of the power unit. In DAF XF 106 trucks, the Delphi Paccar ETC-3 PCI controller is responsible for the proper functioning of the diesel engine.

Issues with the Delphi ETC-3 Engine Computer

These units have a factory design flaw that can lead to a complete controller failure. As a result, the vehicle may suddenly stop working, which poses serious problems for fleet operators using semi-trucks.
The Delphi ETC-3 controller was designed as a non-repairable module—its manufacturer did not anticipate refurbishment or repairs. However, with specialized solutions, it is possible to effectively restore its functionality.

Symptoms of a Faulty Delphi ETC-3 Controller

• Sudden vehicle immobilization without prior warning
• Difficulty starting the engine
• No communication between the controller and the diagnostic system
• Error messages related to the ECU

Repair & Refurbishment Options

With modern technologies and extensive experience in engine controller repairs, we can effectively eliminate the issue and restore full functionality to the module. The repair process includes:

• Computer diagnostics to identify the fault
• Replacement of damaged components
• Post-repair functionality testing

Refurbishing the controller provides significant cost savings compared to purchasing a new module while ensuring long-lasting and reliable engine operation.
