I've got a D6T LAY968. Engine died in the middle of pushing. Not able to see the engine ECM on the laptop. The fuse is good. How do I troubleshoot the ECM? I dont have a schematic. Any help will be greatly appreciated.
Does the laptop show any diagnostic codes, especially anything relating to a lack of communication between ECMs.?
030 0248.02 I'm seeing some active codes for blade tilt right side and left side solenoid valves and a code for control lever position sensor. This machine does not have that type of joy stick on it. It has a regular old pilot operated joystick. Not sure whats going on with these type of codes.
That’s the key. Does it have an Implement ECM.? If so I wonder if it has the wrong software in it, or was maybe pulled off another machine that was set up differently.? Sorry I can’t help you more than that because my computer is down and I cannot access service information, which includes schematics and troubleshooting procedures. EDIT: See this link. The troubleshooting procedure uploaded to that thread should work for your machine as well. Note the comment regarding the Datalink comms wires being a twisted pair. HeavyEquipmentForums
It does not have an ECM for the hydraulics. What's your thoughts on a harness code plug?
Without access to info it’s hard to comment. I just got word that MAYBE I’ll get the computer back tomorrow lunchtime. If that actually happens I may be in a better position to offer advice.
Thanks for helping me with this. Have a good day
On the assumption that I’m going to be back up and running tomorrow why not list all the other Codes you mentioned for blade tilt.
I have a video that shows how to get into the diagnostics menu on a D8T. Click on the link below and let me know if this is the dash monitor that you have.
The 6T monitor is different.
I'll get the codes listed.
Good Morning, Here's the active codes.PID:247FMI:9, PID:1934FMI:5, PID:1870 FMI:3, PDI:1933 FMI:13, PDI:590 FMI:9, PDI:248 FMI:2. Its got a lot going on. Not sure where to start. Thanks for your help.
Just a follow up on the D6T. It had to have a new ecm. All is well. Thanks for your help.
