Komatsu related questions
Good Morning all,
Can anyone here give me information on Komatsu diagnostics? How do they differ from Cummins-drive?
What engine families? What protocols? Which units run diagnostics from the onboard monitors? What are the different procedures to access this data? Do they utilize a 12 pin Deutch connector for data extraction? Is there a OEM diagnostic tool that is separate to the data extraction tool?
Any and all information will be of use.
Hello all, does the lack of responses indicate that no-one here has any information on this subject?
Hi Jaxson, I recently reached out to someone that might have info on this but I haven't heard back.
Hi Scott, thank you for your your reply
I've done work on some komatsu mini excavators in the past. I reached out this morning to a friend who deals with komatsu rather regularly. I will update when I hear back, or try to convince him to join the forum here.
This information may be somewhat dated but here is what I have from personal notes and a few quick texts with my buddy: There is no factory scan tool for komatsu, DTCs, bi directional controls, and diagnostics are all accessed through the monitor (read instrument panel) with different button press protocols (access codes) based on machine configuration and serial number. Larger excavators…
Hello Chris, Thank you When you say J1939 connector are you referring to the Deutch 9 pin connector? Do you have a list of engines / systems that appear on the insite tool? Do you have a list of Komatsu engines in total, and showing those that are common rail? Thank you.
Jaxon, As far as J1939, yes your standard 9 pin I do not have/have access to the Insite tool nor any Komatsu service info. Research is the route to go here. This is one resource I use.
Ask away I am a auto electrician for … In new Zealand. The monitor panel is the electrical hub, were you can get live data and fault codes. There are no bidirectional control. Excavators have a monitor, engine controller and pump controller all on high speed can bus. The dump trucks have additional transmission control and brake controller. Information is not given out easily. The bigger
Hello Michael, thank you and welcome. What high speed bus protocols are used? Also, do you have any lists of any data/information ?
Not sure on the bus protocols to be honest. What do you mean by list of data? What do you want to achieve ? What benift does knowing the protocol give you? I have worked on my network systems, and I have build can systems for hydraulic controllers and in diagnostics it's irrelevant what protocol it is. It's just wires
