Just Arrived

[cyberbob]

Just got my 2012 Toolcat 5610 (ordered oct. 11' with all options even Sirius sat radio) delivered from the dealer Friday late afternoon. I've been using it for a few task totaling 2-3 hours over the weekend and noticed a few quirks I would like to pole the forum community for advice on.


1. Saturday AM when I moved the unit from it's parking spot I noticed a 3-4" diameter oil / fluid spot underneath the front driver's side of the drive motor on the concrete slab.
2. Once over the past two days when starting up I received the error code 50-08 "PDR sensor multi response". After stopping and starting the unit a few times the error went away.
3. Saturday PM and Sunday AM when I went to start my TC up I got the error 50-56 "can bus comm. error". As with the other error after cycling the unit from start to stop a few times it went away. FYI on both error all function of the unit worked except for drive forward and reverse until error was cleared.
4. On all startups I get a brief puff of black smoke from exhaust. I'm used to that on my older model ford powerstroke dually but it surprised me coming from a new diesel machine. Unit had 4 hour on it when delivered.
5. My unit is plagued by the constant ac compressor cycling issue. Dealer did provide a service document upon delivery noting that the factory engineers are working on the issue with a possible solution soon.
6. Sirius Sat radio option would not display on the radio. I dropped the center overhead console panel and found that the Sirius sat tuner data cable was not connected. I completed the connection, registered the unit online and all was working again.

Please let me know anyone's thoughts on these issues I'm having on a my new 5610. I'm going to contact the salesperson from the dealer first thing Monday, but any feedback I could get would be greatly appreciated.

I'll be glad to post the progress of these issues as they evolve as it may help other owners in the future.

my only comment is I have a 5600 delivered last OCT, and I notice it smokes more on startup than any other machine I own I assume once I changed oil on 50 hours it would improve but it did not.Turbo's tend to smoke more on start.
have not had anyother issue no error codes!
check your hour meter it appears that every 6 minutes regardless of RPM setting one tenth is read, I always assumed it was one tenth every six minutes at rated horsepower/RPM.
all my other machine calculate one tenth that way.

otherwise great machine!

My big concern is the error codes - especially since on all occasions it shuts down the drive function till cleared. I would assume the fluid leak will be something I will have from time to time with so many hoses and valve blocks. Just has me worried in a new machine.

The 50-56 error is the likely source of your other electrical gremlins, though not the smoking on startup. The main controller sets this code when it has a hard time sending messages on the CAN bus, which is the communications network between the controllers and sensors on this machine. On a new machine I would suspect this is due to a pin not being fully seated in the harness connectors to the controller, but it could also be caused by a damaged/pinched/grounded wire harness. When the communications are flaky, information from the sensors and other controllers may be delayed or not available at all, so you get other error codes for those specific sensors, but the root cause is the compromised CAN bus communication.

It could also be a defective controller or sensor, but on a new unit I would think this is the least likely cause. I had a very intermittent 50-56 on my 2004 B series that I tracked myself to the pins backing out of the connector at the display in the dash. Just had to remove the connector to see if any of them are sitting lower then the others, then grab that wire and push it into the connector until it locks in. Tug on it a couple times to make sure it will stay, and then plug it back together.

Welcome to the forum and to your new Toolcat cyberbob,

My '09 5600 puts out a puff on startup as well, I consider this normal. I don't know what the compressor cycling is all about. I did have to add some R134a to the system last week because it wasn't cooling as well but it wasn't doing the typical fast cycling when your low on refrigerant either.

As far as the fist 3 items on your list, I'd suggest giving the dealer's service dept. a call and have them come out and address all three issues. I'm surprised they didn't notice any of those problems when they did the dealer prep on your 5610.

Let us know how it works out for you.

Make darn sure your dealer knows the problems and records them in case you have to have some warranty work done later.
My Toolcat has been a great machine, but it's so complicated many dealers don't have the necessary training to do service work correctly.
Bobcat has a good warranty and they've went above and beyond on mine.

UPDATE:

I forwarded all my concerns to the dealer yesterday.

They are looking into everything and evaluating actions on each.

Last night when i returned home I started the unit after it had been sitting for 8+ hours and immediately got the 50-56 can buss error code when started.
Again I cycled the unit start and stop 3-4 times and it went away.

Does anyone know the harness number on the back of the dash display that contains the can buss wiring (J1-7)? I've heard where it can be a improperly seated pin from the factory that can sometimes cause this error.

Thanks,

CyberBob,

I had the very same issue several yeasr ago with one of my B series TC's. If you PM me with an email address I will send you a diagnostic procedure that was given to me while we were trying to resolve the 50-56 error code. The sheet does indicate the two comm wires you are looking for.

Update:

I've reseated the can buss connector on the rear of the dash CPU and am almost 24 hours error free. I used a rented auger attachment to plant several "hubby do's" around the house during which i started and stopped the engine countless times.

I'll have to admit its hard to exit the cab in the Mississippi early heat to drop a plant in the hole when the cab is near 60 degrees from the ac and the sat radio is playing on my favorite commercial free station. Oh well, at least it gives you something to look forward to getting back too after each task while out. This thing truly is a dream machine for all tasks as long as it behaves.

Excellent!

I have a 2011 5610. Love it. No real issues to date. Hydraulic tank leaked a little when I overfilled it. I think this was coming from sight glass seal. Does not leak when level normal.

Ac will freeze up when running blower to slow or if filter clogged.

I have 200 hours on machine and have used it for all kinds of stuff. What part of ms are you in? I live in lucedale ms. Se corner of state.

I put a trailer wiring harness on mine for towing trailers on road. Best addition is a 1500 watt inverter hooked straight to battery with 200 amp fuse. Inverter is behind passenger seat. Put grommets in for wiring and have plug on r side of machine and one on front (zip tied to front hydraulic bundle).

I have been amazed with how strong that front arm is. It is only about 10 inches wide but I have carried 18 foot logs with it. Pushed with edge of bucket accidentally. Have not bent arm as of yet.

I love being able to bushhog with my girls in the passenger seat. Wife has used it to unload trucks. People laugh at it until they see it work. Awesome machine. I plan to trade in on a new one after I pay it off.

Pallet forks are handy. 4 in 1 bucket is great. Found a dozer blade and in process of getting. Trying to get yard ready to use 90 inch mower.

Hope you enjoy yours as much as I have enjoyed mine. I would have the dealer address those issues since the machine is new.

What, you couldn't get the "boss" to stand outside and do the planting while you dug the holes? :laughing::laughing:
Don't let her get behind the wheel or you will be standing out there or riding shotgun while she gives instructions.

 

[hardhat]

Pics of inverter. Inverter behind pass seat. Wires to inverter viewed from below. Plug in on side with wire to front of machine plugged in. Plug on front of machine.

Have 200 amp fuse in hot wire going to inverter to prevent badness should one of the big wires to inverter get shorted

Year Later Update....... 50-56 still occurs Re: Just Arrived

Well.....
it's been over a year and my 50-56 can bus error code is still occurring at start up. This code keeps the machine from moving F or R until it clears.

So far my Bobcat dealer has replaced the following:
1. Dash CPU Controller 02/13
2. Rear Drive Controller 03/13
3. The Entire Machine's Wiring Hardness 04/13
4. Drive Petal Assembly 07/13
5. Updated Firmware / Software in the Machine 07/13

Yet the 50-56 error code is still happening almost daily when you first start the machine. Also sometimes it reoccurs if you briefly stop (5 or so mins.) and restart after it's been running for a while. It never shuts down the machine and always clears after you cycle the start / stop 5-10 times. I've only got 78 hours on the machine and always keep that code in the back of my mind when using it that it could act up and stop what I'm doing.

I've been in touch with Bobcat directly and been referred to the Regional Rep. for a few months and they tell me: "We'll make this right".

My opinion is, and still is, since the start that it needs to be shipped back to the Bobcat factory for them to take care of the problem. The error occurred the night it was delivered in March 2012 and they are considering it to still be a "Warranty" issue - which is a good thing since the warranty is out since March of this year.

Has anyone else had such a problem with their Toolcat 5600 or 5610? If so was it resolved and how? All the threads and posts I've seen on the 50-56 error have been older machines - never one new under warranty.

Re: Year Later Update....... 50-56 still occurs Re: Just Arrived

Cyberbob,
I have three B Series Toolcats and did experience the 50-56 error code on one of the units over a period of 14 months. The first the error codes were intermittent and could normally be cleared after restating but not always. There would be times that the driver would be ‘roading’ between contracts in high gear and the unit would throw the code and lock up coming to a complete stop. Sometimes I would have to pull the center console and disconnect then reconnect the wiring harness to the controller on the firewall. The dealership was pulling their hair out trying to resolve the problem and changed out controllers, etc.
Ultimately one of the techs at the dealership discovered that one of the connectors at the dash controller was just loose enough that when the unit was running down the road it would break the connection causing the unit to skid to a halt.
Hope this helps…

I wonder if it could a voltage problem?

Can you put a digital meter on the 12 volts at the Dash CPU Controller, and see what it does when starting?
Might need to use an oscilloscope to look for voltage spikes.

Does it make any difference if the safety interlock arm is up or down when starting?

Does it have the keyless start option?

It does have the keyless dash cpu and the code has happened when starting both with the safety arm up and down.

I haven't metered anything myself. I've been leaving diagnostics to the dealer so far since this issue is considered still under warranty.
Due to the massive amount of money Bobcat has spent on this warranty job, I would assume they have ruled out this being an issue.

I will however double check with the service manager that it was ruled out.

Late yesterday I spoke with the dealer with the idea to change the joystick control and drive select lever. He said that is all that's left parts wise that could cause any 50-56 error to return at start up according to Bobcat. They're waiting on Bobcat corporate to approve this next parts swap.

Since it has only occurs at start up, we've pretty much ruled out any intermittent connector issues. It has never happened after the machine starts code free during use. Also, when the entire wiring harness was replace all of the connectors were double checked.

Too bad they don't know how to troubleshoot, throwing parts at it may not fix this one!

I was employed as an electronics technician for 34 years, working on computers and fax machines. Voltage spikes can be very hard to track down. The problem could be found with a logic analyzer, but I don't think they would have one or even know what it is.

cyberbob, we need an update please.

 

[cyberbob]

Nothing new with the 50-56 code issue. It has came back 4-5 times over the past two years but always cleared after cycling the keyless ignition 2-4 times.

Bobcat's last response was "they couldn't proceed any further unless the code occurs and doesn't clear" I guess I see their point......
