Komatsu ECM Part Numbers

TOSOG can identify and source controllers using the Komatsu part number printed on the module.

Examples of electronic module references encountered in Komatsu equipment include:

7835-26-1009
6560-61-1502
6560-61-1503
Other 783x-series electronic controller numbers
Model-specific controller part numbers

For example, Komatsu’s parts system identifies 6560-61-1502 as an ECM controller assembly and lists 6560-61-1503 as its latest replacement product.

Important: A part number should always be verified against the machine serial number and application before ordering. A visually similar controller is not necessarily interchangeable.

Komatsu Engine ECM Applications

Komatsu equipment can use different engine families depending on machine model, production year and market.

Controllers may be associated with engines such as:

Komatsu SAA4D95
Komatsu SAA6D102
Komatsu SAA6D107
Komatsu SAA6D114
Komatsu SAA6D125
Komatsu SAA6D140
Komatsu SAA6D170
Komatsu SDA16V160
Cummins QSB
Cummins QSL
Other engine configurations

The engine model and engine serial number are therefore important when identifying an ECM.

ECU / ECM Manufacturers & Technology Suppliers

Electronic control systems used on heavy equipment can involve several manufacturers depending on the machine generation and application.

Common manufacturers and technology providers encountered in heavy-equipment electronic control systems include:

Komatsu

Komatsu manufactures and supplies electronic and electrical components for its equipment, including genuine electrical parts designed to Komatsu Engineering Standards.

Cummins

Cummins engines used in certain equipment applications may use Cummins engine control modules and electronic engine management systems.

Denso

Denso supplies electronic and engine-management technologies used across heavy-duty and industrial applications.

Woodward

Woodward develops electronic control systems and engine-management technologies used in industrial and heavy-duty applications.

Siemens

Siemens electronic and automation technologies are encountered in industrial control applications and certain heavy-equipment systems.

Other OEM / Specialist Suppliers

Depending on the machine generation, application and controller function, electronic components can also originate from specialist OEM electronics manufacturers and suppliers.

TOSOG identifies the actual controller and application before recommending a replacement rather than assuming that all Komatsu machines use the same ECU or ECM.

New, Used & Reconditioned Komatsu ECM

Depending on availability, TOSOG can source:

Genuine Komatsu

Original Komatsu electronic components supplied for the applicable machine.

OEM

Electronic modules manufactured by an original equipment manufacturer or approved component supplier.

Aftermarket

Replacement controllers manufactured for a specified application.

Used

Previously installed electronic modules that may be suitable for replacement applications after verification.

Reconditioned

Controllers that have undergone inspection, repair or refurbishment, subject to supplier availability.

Exchange Units

Exchange or remanufactured solutions may be available for selected applications.

Komatsu itself also offers Reman components as part of its lifecycle-support offering.

Why Correct Komatsu ECU / ECM Identification Matters

An ECU or ECM is not simply a plug-and-play electronic box.

The correct controller may depend on:

Machine model
Machine serial number
Production year
Engine model
Engine serial number
Controller part number
Controller hardware version
Software version
Machine configuration
Market specification
Harness configuration
Connector arrangement
Transmission configuration
Hydraulic configuration

Two machines with the same model designation can potentially have different controller configurations.

This is why TOSOG recommends providing the complete machine information before ordering.

Common Symptoms of a Faulty Komatsu ECM / ECU

A defective or communication-related controller can potentially result in:

Machine will not start
Engine does not crank
Engine cranks but does not start
Loss of engine power
Incorrect engine speed
Excessive fuel consumption
Warning lights
Diagnostic fault codes
Intermittent machine operation
Communication failure
CAN-Bus communication faults
Hydraulic functions not operating correctly
Transmission shifting problems
Limp-home mode
Sensor communication errors
Injector-related faults
Unexpected engine shutdown

However, these symptoms do not automatically prove that the ECM is faulty.

Wiring, power supply, grounds, sensors, communication networks, connectors and other control modules should also be checked.

TIPS When Buying a Komatsu ECU or ECM

Tip 1 – Send the Complete Part Number

Take a clear photograph of the controller identification label.

Make sure the photograph shows:

Part number
Serial number
Manufacturer
Model/reference
Hardware number
Software information where available

Tip 2 – Provide the Machine Serial Number

The machine serial number is one of the most important pieces of information for controller identification.

Tip 3 – Provide the Engine Details

Send:

Engine model
Engine serial number
Engine dataplate photograph

Tip 4 – Photograph the Connectors

Send clear photographs showing:

Front of controller
Rear of controller
Connector plugs
Pin configuration
Mounting points

Tip 5 – Do Not Order Based Only on a Photograph

Controllers can look identical externally while having different software, hardware or calibration.

Tip 6 – Check Programming Requirements

Some replacement electronic controllers may require:

Programming
Configuration
Calibration
Parameter setting
Machine identification
Software installation

Always establish these requirements before purchasing.

Tip 7 – Confirm the Fault Before Replacing the Controller

Before replacing an ECM, check:

Battery voltage
Power supply
Ground connections
Fuses
Relays
Harness continuity
CAN-H
CAN-L
Connector condition
Sensor circuits
Communication with diagnostic equipment

A wiring fault can sometimes produce symptoms that appear to be an ECM failure.
