Can data link loss 299d3

[emostock]

Having some issues with my cat 299d3. Only has 85 hours on it. I don't use it often but the other day I was using it and it all came to a stop. And the can data link loss came on screen no functions worked I shut machine down turned battery connector off for 30 min and back on was fine. Today I started it few minutes later it shut down and same fault. This time after disconnecting battery won't turn on or do anything just that fault. has 12.8v I checked battery connections and grounds I checked the ohms on diagnostic port and it's 58.9 ohms what should I look for next before I bring it to dealer and pay thousands

Couple of thoughts.

1. Try resetting the display.

• Key off
• Disconnect battery for a few minutes
• Reconnect battery
• Key on
• Press and hold the two outermost buttons on the display for 15 seconds.

2. If option 1 does not work, try disconnecting the battery overnight.

Post a Serial Number. You are probably going to need an electrical schematic.
Meantime I will look up the troubleshooting procedure(s) for a lost CAN Datalink.

Between which two pins where you measuring resistance.?
To test either of the two datalinks really requires a Pico scope.

 

[emostock]

I tried option one no luck

 

[Nige]

Ah, you have ET. That makes it easier.

I see from that screenshot it says Active Codes present. Got a list.?

EDIT: Note for future reference. You posted in the wrong section, this one is for full-size steel track machines. I have requested that your thread be moved to the CTL/MTL section.

Those are all FMI13 "requires calibration" Codes, not failures per se.
How exactly did you get into the situation where you are now.?
Has the software in any of the machine ECMs been updated recently.?

Not recently I had the machine deleted and ecm updated for def dpf egr delete but that was when I bought it new I did it at around 5 hours been good till now 86 hours on it. I was just moving some metal with the forks. And it stopped dead in its tracks. But was still running with the data link lost on screen. I shut it down killed battery switch for 20-30 min and it was fine. Drove it back to the driveway shut it off started it yesterday and right away it shut down on me and thru same fault on screen and now I can't get it to start back up or get rid of fault

It's a good job you are in Canada or the conversation would have ended right there. It's not forum policy to assist with deleted machines in markets where the aftetreatment system is a legally-mandated requirement.

I checked the ohms on diagnostic port and it's 58.9 ohms what should I look for next before I bring it to dealer and pay thousandsI don't know what the dealers are like in Canada but in the US no dealer would work on a deleted machine.

I don't know what Canada is like but in other markets no dealer would agree to work on a deleted machine for fear of incurring the wrath of the relevant authority.

There are two 60-ohm terminating resistors on the CAN Datalink, so you should have measured 30 ohms not 60. Maybe that's the first place to go looking. Confirm you were measuring across Pins F & G on the service tool connector.?

I'll send you an electrical schematic. Keep an eye on your messages.

Do you have a contact for the company that did the delete?

I also see by looking at your et screen that the engine ecm is not available. It should be showing up when you connect et.

 

[emostock]

I know it's not from the delete as I've put 80 hours on it since delete and I only had 5 hours on it when I deleted it. Yes in Canada and don't have the regulations like some US states do I'll check again when home the resistance

I wouldn't say that is necessarily true. Just because it worked OK for X hours after whatever was done to it does not mean you can rule out the possibility of an issue with what was done previously and worked fine - if you get my drift. Don't rule it out.

As @Mobiltech says, the fact that the engine ECM is not appearing on the ET screen is a potential indication of either a comms issue (CAT or CAN Datalink, or maybe both) or an internal problem within the engine ECM.

I'll check again when home the resistance

Make sure you are checking the correct pins for the CAN Datalink. See above.

Could the lack of engine ecm comm be a result of a bad ground strap on the engine like the 259/279d have from time to time.
Was it deleted via programming or a sensor fooling device

 

[Mobiltech]

The reason I asked about the delete provider is that if you end up replacing or reflashing the engine ecm for any reason you will have to get the software installed by them in order for it to work.
The dealer will only install the cat factory software which will no longer work in your case.

Yes deleted via programming sent the ecm out 80hours ago

Why why why would someone delete a 5 hrs machine?
Before you take that all wrong I not a fan of emissions, but, we are now all thinking might be a delete issue.
I have replaced 2 ecms due to hardware failure weeks or years after a delete. One the tuner apparently has to disassemble the ecm and an internal screw rattled loose and shorted the injector driver. Another the vent plug was nor put back in and rain water funneled into the ecm. Then the whole ball game of needing to have the ecm programmed and then refreshed with the delete. It's just not as cool as it's cracked up to be.

They didn't open the ecm just plugged into it on the bench so no vent plugs or screws were touched

Deletes are done on the machine through Et with teamviewer.
At least that’s what I’ve heard.

 

[Nige]

As a new member you may not be aware that it is forum policy not to supply advice regarding any system designed to defeat legally-mandated emissions devices. So you’re probably advertising in the wrong place.

Lots of misinformation in here surrounding delete process from people that are quite obviously not familiar with it.

@emostock this is 100% tuner issue and you need to get them back on the phone and connected to the machine. They flashed the wrong ECM, most likely copied/pasted from wrong folder or your machine is the first time they've worked with that model. You are well on your way to a $100k brick, and if you take this to a dealer you will a check for $20k to get the emissions equipment reinstalled. Your other option is finding a non-CAT mobile tech that will actually work with you vs the dealer employees. $180/hr, have fun.

I have to laugh at anybody that says stuff like "why would you delete a machine with 5 hours on it!"
