Previously used electronic modules that have been professionally refurbished or remanufactured.

Used ECU / ECM

Used controllers may be available for older machines where new modules are difficult to source.

Important: A replacement module should only be purchased after confirming its exact application, hardware configuration, software/programming requirements and part-number compatibility.

Common Komatsu ECU / ECM Failure Symptoms

A failed or malfunctioning controller may be associated with symptoms such as:

Engine will not start
Engine starts and stops
Loss of engine power
Machine derating
Incorrect engine speed
Poor engine performance
Warning lights
Diagnostic fault codes
Communication errors
Intermittent machine operation
Hydraulic control problems
Transmission control problems
No communication with diagnostic equipment

However, these symptoms do not automatically mean the ECU or ECM has failed.

Wiring faults, poor grounds, damaged connectors, low battery voltage, voltage spikes, sensors, CAN-bus communication faults and other electrical problems can produce similar symptoms.

Tips When Buying a Komatsu ECU ECM

TIP 1 – Do Not Match by Appearance Only

Two Komatsu controllers can look almost identical but contain different hardware or software.

TIP 2 – Send the Complete Part Number

Photograph the controller label and send us the complete number.

TIP 3 – Provide the Machine Serial Number

The serial/PIN helps identify the correct machine configuration.

TIP 4 – Provide the Engine Model

Engine configuration can affect ECU/ECM compatibility.

TIP 5 – Send Photos

Provide clear photographs of:

Controller label
Part number
Serial number
Connectors
Connector pins
Machine data plate
Engine data plate

TIP 6 – Do Not Replace the ECM Before Diagnosis

Check:

Battery voltage
Grounds
Fuses
Relays
Wiring
Connectors
CAN communication
Sensors
Power and earth supplies

before condemning the controller.

TIP 7 – Confirm Programming Requirements

Some replacement controllers may require programming, calibration, parameter configuration or machine-specific commissioning.

TIP 8 – Keep the Original Controller

Do not dispose of the old ECU/ECM until the replacement has been correctly identified and commissioned.

TIP 9 – Check Connector Configuration

Connector shape alone is not enough. Pin configuration and controller specification must be confirmed.

TIP 10 – Tell Us the Machine Application

Tell us whether the machine is used for:

Mining
Quarrying
Construction
Roadworks
Agriculture
Plant hire
Material handling
