Error Code 50-56...

[timm9]

Has anyone had this error code before? I'm 3 hours from the dealer and all of a sudden I get this code and warning light. Unit will not go forwards or backwards. Shut it down and wait about 5 minutes and it will move again. After about 5 minutes error code and warning light again. The only thing I have done to the unit since last operated is clean, lube, and charge the battery. Error code reference in manual says "CAN comms error."

I called the dealer and was told that it "sounds like a computer issue."

Any suggestions, ideas, or experiences along these lines would be greatly appreciated.

Thanks!

Tim

I can't remember the exact code but that sounds fimilar, I had the same problem and they checked the connections first, but all the electrical connections were good so they had to order a new control box for the drive system and that fixed the problem.

Don't know that error code, but must have to do with the drive system. My a just gave an error code 50-15 which isn"t in the manual, either the operator manual ot the factory shop manual. My dealer says there is no such error code. This code showed up several days after the inital problem. I had backed out of the shed, and when I put it in reverse, all the wheels spun in different directions, digging 4 holes. After shutting down the engine and restarting several times, it went forward and mowed for 4 hrs with no problem. Days later, same thing, no go, no error code. Two days later, error code 50-15. Today, the stupid thing won"t go, but digs very nice holes. I cant move it or get it up on a trailer. Dealer will fix if I can get it there. Any Ideas?????????

goatman,

I am picturing the front wheels both trying to pull the machine forward and the back trying to pull it backward. The mental picture has me laughing. Probably not too funny from your view.

The front and back drive motors are indendent. Does each tire reverse direction when you switch from forward to reverse? Which axle spins according to the forward/reverse lever?

Without digging into the manual I am wondering if there is a problem with the forward/reverse lever or following the harness from the lever as it travels towards the axles, a connector off somewhere.

Have you tried putting it in 2 WD? Is there a "reboot" or "reset" procedure of some sort?

All sorts of mysterious computer problems seem to vanish after a reboot.....until next time. May at least get it on the trailer.

Good Luck,
Rip

disconnect your battery for about 5 minutes.
then hook it back up, that should clear your computer codes

Thanks for the ideas. The toolcat has no 2wd settings, is constant 3wd. I say 3wd because the only time I have 4wd is when the axles are turning against one another. I checked to see which way thy are turning--in forward the front go forward and the backs go backward. The opposite is true in reverse. However, I think my toolcat got jealous that I was using the John Deere for mowing, because my wife went to get it to clean the horsebarn, and it went like a new one. Go figure.

It's back!

I知 assuming the correct thing to do is resurrect this thread as opposed to starting a new one. If this is incorrect please accept my apology and move it where ever you feel is appropriate.

As you can see from the previous post(s), I had an issue with the Bobcat Error Code 50-56. After the new console CPU was installed all was good until February when we had 15 days of straight snow totaling 6 ｽ feet, and the Toolcat started to lock up again with the 50-56 error code.

The dealer found that they could not find an available console CPU in the country! The dealer actually cannibalized another unit in their yard to get me back up and running. The temporary CPU worked for about 3 or 4 days and then it too was locking up with the 50-56 error code.

The dealer was able to find a new console CPU and came to me to install it. Everything was fine for approximately 60 to 70 hours which finished off the season. About a month ago, I started collecting my equipment from the driver痴 residences and bringing them back to the barn. The Toolcat sat unused until Monday night when I used it (or more accurately tried to use it) to move a trailer. It had only run about 10 minutes and locked up again with the error code 50-56. To make matters worse, it locked up sideways at my home blocking both garage doors and our daily drivers.

Out of desperation I pulled the driver痴 seat, center console, etc. and disconnected the wiring harness to the drive CPU controller and popped the dash console and disconnected the corresponding wiring harness. I reconnected both harnesses again and was able to move it out of the way. While the disconnect/reconnect does not solve the problem, it does allow some sort of reset so you can move the unit. Thank God it痴 summer!

The dealer is working on the issue but I wanted to post the most recent chain of events. Hopefully we will get to the bottom of this once and for all this time. I will post what ultimately happens! I still love my Toolcat(s), and I really love my dealer!

I had a couple weird electrical issues with my 2004 Model B, and had to solve them myself because the dealer wouldn't take the time to actually find the root cause.

First issue was also a CAN communication error, long story short it was a pin in the wiring harness connector to the controller which was not fully seated. This controller module is located on the back wall of the cab, between the seats. I would recommend that you remove the connector and visually look at each pin (well, socket actually, the pins are on the controller) to see if any are not all the way at the mating surface of the connector. You can also pull on each wire individually to see if any pull back. If they do, push it all the way in and see if it locks. If so, your done. If not, then pull that wire all the way out and tweek the tab that sticks out the side a little and reinsert. If they don't lock into the connector, they will eventually vibrate out.

My second wiring problem which may be causing your issue was caused by the engine rubbing through the wire harness, grounding out the wires. My dealer 'fixed' this for me under warranty by bypassing the first wire to short out with another loose piece of wire, not a very good fix. And ultimately the reason I'll never have my dealer do any further electrical work! The location was the front corner of the cylinder head, center of the vehicle under the seats. Kind of a tough location to get to, but I highly recommend investigating this location for harness damage. It was a couple years ago now, but as I remember there is a clip in this location holding the harness to the engine, and I had to bend it away from the cylinder head a little. It was very had to see the rub through, I recommend using a little mirror. It's even harder to repair the wires, but the could easily be the cause of your intermittent CAN error. Basically anything grounding either CAN high or CAN low will squash the communications between all modules. If they were routed correctly in the first place, it would never have been an issue. Instead I had three repair trips to the dealer, and the two days I spent tracing the actual problem down and repairing it so it would not re-occur. Lesson learned!
