CAT excavator CANbus location

[Raul Ramirez]

Hello! Does anyone know where to find the CANBUS location on a CAT 320D/320D2L year 2013, also Caterpillar 416E/F2; I have to install a contactless canbus reader (CANcrocoLITE from Technoton) using a device called "Mastercan Tool Lite", I tried several twisted pair (green/yellow, green/brown) of cables but I didn´t get a reading; note that I don´t have any issue with motorgraders 140/H/K, 12M using the same twisted pair colors (green/yellow)
Thanks in advance for the help

The wires for the CANBUS twisted pair (if installed) are usually marked F711/F712. The wire base colours are Green and Grey.

I suspect that the Green/Brown twisted pair that you were tapping into on the motor graders are for the Cat Datalink. They are wire numbers 892 & 893.

Many machines could have both Datalinks in the wiring harness, especially new models. Older models may only have the Cat Datalink installed. A brief look at an electrical schematic for a 140H motor grader confirmed that.

Hello Nige and thanks for your reply; by any chance do you know where I can find electrical schematics for Sinotruk Howo 371, Liugong 856H, Liugong 922/925 excavators, we tried to install the canbus reader but in the Sinotruk we found some twisted pair light blue/light blue&green but we didnt get a reading either, on the Liugong machines we couldnt find any twisted pair of cables (there are a lot of orange and white cables but none of them twisted)
Again thanks in advance for the help.

Sorry I can’t help with schematics for anything other than Cat machines.

Do you have schematics for cat 323, 320D, 320D 2L, 336, its with the excavators that I´m having a bit of trouble to install the canbus reader.
Thanks in advance

Can bus wires are in the diagnostic connector.

Good day, do you perhaps know the PGN and SPN and bits that current gear can be read from a CAT loader?
