Product Overview

The 2480U310F3 CPU Controller is the primary electronic control module for your excavator. It receives input signals from sensors and operator controls throughout the machine, processes this data according to its programmed logic, and outputs commands to govern engine RPM, hydraulic pump flow, solenoid valves, and monitor system health. Our replacement controller is an exact match for the original, designed to plug directly into the existing machine wiring harness and mount in the standard location. It is the definitive solution for resolving complex electronic issues that are traced back to the main computer.

Key Features & Benefits

• Direct Plug-and-Play Replacement: An exact-fit replacement for part number 2480U310F3, guaranteeing perfect connector compatibility and seamless integration with the electrical system of your Kobelco SK120-3 or SK200-3 excavator.

• Resolves Complex Electrical & Performance Issues: Replaces a faulty unit to fix problems like engine derating or stalling, unresponsive hydraulic functions, erratic operation, warning lights, and diagnostic communication failures.

• Restores Factory Performance Parameters: The controller contains the original factory programming for engine horsepower management, hydraulic pump control, and safety interlocks, ensuring the machine operates as designed.

• Essential for Machine Operation: Modern excavators rely entirely on this ECU. A failed unit will often prevent the machine from starting or operating correctly. This replacement restores full functionality.

• Durable, OEM-Quality Construction: Housed in a robust, sealed case to protect the internal circuitry from moisture, dust, and vibration typical in heavy equipment environments.

• Cost-Effective Core Repair: For a confirmed faulty ECU, replacement is the most reliable and often most economical repair path compared to extensive diagnostic time and component swapping.

Frequently Asked Questions (FAQ)

Q1: What are the symptoms of a failing main CPU controller (2480U310F3)?
A: Symptoms can vary widely but often include:

• Machine will not start or crank (with good power and starter).

• Engine runs erratically or shuts down unexpectedly.

• Loss of hydraulic functions or weak/uncontrolled movement.

• Multiple, seemingly unrelated warning lights illuminated.

• Diagnostic tool cannot communicate with the machine’s computer.

Q2: Is programming required after installation?
A: Typically, NO. The 2480U310F3 is a direct replacement controller that should come with the necessary base programming for the SK120-3/SK200-3. It is a “plug-and-play” unit. However, it is always advisable to verify this with the seller before purchase.

Q3: Can I install this controller myself?
A: Physically, installation is simple: locate the old ECU (usually in the cab or under the seat), disconnect the battery, unplug the wiring connectors, swap the units, and reconnect. However, proper diagnosis is critical. You must be absolutely sure the controller is the cause of the problem, as it is an expensive part. Misdiagnosis is common. Professional troubleshooting is highly recommended.

Q4: How do I know for sure my controller is bad?
A: Diagnosing a faulty ECU requires a systematic process by a qualified technician. This involves checking for power and ground at the ECU, verifying input signals from sensors, and ruling out other potential causes (like faulty sensors, relays, or wiring harness issues). It is rarely the first component to suspect.

Q5: Is this a new, used, or rebuilt unit?
A: This may be a new old stock (NOS) OEM unit, a quality used unit tested from a working machine, or a professionally repaired/refurbished unit. The reliability and warranty will vary greatly depending on the source. Always confirm the condition, origin, and warranty with the seller.
