Bobcat ACS error code 32-49

[catdozer]

Need help with the code. Its a 2006 t190. It will work just fine then throw a code. Where do i start? Ssdoxie?

32-49 is Lift Actuator Short to Ground:
Is code 32-65 also present? If not try steps listed in order.
1. At the control valve swap the actuator harness connectors (connect lift to the tilt harness plug & tilt to the lift). If code changes to 32-50 the Lift actuator is shorted internally - replace it.
If code does not change
2. With harness unplugged at actuator, check for continuity on wires #4670, 4680, & 4690 to ground. If continuity to ground is present on any of these replace harness.
3. Check continuity on wire #4670 at actuator plug to controller plug. If open circuit replace harness. If continuity is present, wiggle/twist the harness to see if connection opens - looking for a partially broken wire at this point.
Note: Also inspect pin connections in the plugs looking for a loose or corroded connection. No signal to the controller in 4670 wire will trigger this code, same as short to ground.

If you do need to replace actuator check the software version in the machine if it has not been updated in past 1 1/2 years. New actuators require 54.6 (believe that is correct version #) or newer. There is a tag on the actuator stating version need. With key on press & hold the Bucket Position button until a number shows in the display.

Thank you. Nope just 32-49 is showing. After awhile it stopped throwing code and worked just fine for the rest of the day which was about 4 hours, im about 80 miles from the machine so it will be monday till i get back. If it turns out to be an actuator, how much and how hard are they to replace? Should i do both?

Actuator is somewhere in neighborhood of $550. Not hard to change if you have set of Allen screws for 1/4" drive ratchet. Just be sure to get new screws with the actuator, tighten them on evenly, and just over snug (13 in/lb.). Be sure get the part number from old actuator or take it with to dealer, depending on age and serial number of machine there might be a revision to mounting color needed.

I recommend having dealer install it because he can easily verify correct software version is installed, plus when dealer calibrates it using his Service Software it also checks the control valve for binding or sticking in the spool that could cause actuator to work harder and fail sooner.
As stated before, you do need to check/verify what software version is currently in the machine. Running the latest style actuator on old software will reduce life of the actuator.

Replace both? Look on you current actuators, if there is a sticker on it stating to use software version "xxx" then I would wait for tilt to fail. If there is no sticker on them, if it were mine and planning on keeping the machine for a long time, I would replace them both.

Could you walk me through the process of replacing them? I ordered the lift to replace. And which side is the lift? One I undo the mounting bolt is there anything on the shaft to remove to take it off? Thanks!

 

[SSdoxie]

Undo the 2 Allen-head bolts then pull back on actuator to expose push pin that goes through actuator tube and eye in end of the spool. When putting actuator on tighten the 2 bolts evenly and DO NOT torque tight, just snug it up. Best if you get new bolts for this, they will come with Loctite pre-applied so no chance of dripping thread lock into actuator or valve. Lift spool is the bottom one of the 2, first spool in the series, closest to inlet flow.
Caution: the new Actuator requires a minimum software version in your machine controller, it will have a tag on it stating the software number. With key on; push and hold in the Bucket Positioning Button, hour meter window will display the software version loaded in you machine. If you number is higher than the tag on actuator your OK, but do need to go through the calibration process.
I always recommend having the dealer to the install because he can update if necessary plus calibrate with the service computer will also check the valve for any abnormal resistance in the spool, or voltage drop in the wiring.

Thank you! So much! The machine was dropped off a couple weeks ago to have the update, but they wanted a $890 to put ONE actuator on 1500 For both. And that's not including parts! So I have the actuator just need to install I this weekend, once I have it installed I will take it back in for them to do a scan on it.

Also on a friends machine (also a t190) we have been getting a low voltage spontaneous, once a month then to could get it 10 times a day. Ideas?

 

[SSdoxie]

Treat the low voltage warning the same as any other machine with early signs of battery or charging problem. Check/clean cable connections at both the battery and terminal ends (positive & ground connections), load test battery, and check alternator charge. Only difference is the controller can detect a voltage drop in the system before the battery shows weak or sluggish cranking problem. If everything in engine compartment tests OK, follow the harness to front of the machine, checking each plug connection (red wires) for signs of corrosion of loose connection. Corrosion in the fuse panel can cause this too.

So I can't get the new screws. Bobcat said they can't get them for 2 weeks. So could I just get the correct size at the local farm store instead? Also would you happen to know what size the Allen screw is? Was going to buy the correct 1/4 I need and match with the new screw.

 

[SSdoxie]

You can reuse the screws if you can't get new, just put a dab of low torque thread sealant on them and let partially dry before use. I think the allen head is 3/16" not positive. Reason for the Loctite sis too keep from vibrating loose, only want to torque screws to about 90 in/lb.

Ok will do. Man I love the equipment but **** my dealer is getting pretty ******.

 

[catdozer]

Got it changed out went easy used 3/8 drive ratchet with 3/16 Allen. Version on actuator was v63.0 and bobcat showed 80.8, fired right up and didn't seem to have any problems or codes.

Thank you SSdoxie your help is really appreciated!! Couldn't have done it without your help!

 

[SSdoxie]

you're welcome. Actuator still needs to be calibrated for maximum life out of it. The calibration process allows the controller to identify when the valve spool is at end of its stroke so the controller can stop the voltage to the actuator at that position to prevent loading the actuator motor in a stalled position.

Hello, jumping on this thread as it seems like i have some of the same issues... wonder if Farmerpete ever found his problem !
i have a T140 2007, it has the SJC with 2530 hours on it. im running in some issues with it. i started to have some trouble with my ACS where, i could be working with it and it would throw the ASC light on and the lift/tilt control would stop working (i could still be driving though) so i've been shutting it down, starting back up and it would work again.
the control panel was out of comission (where the gas gauge and hours are) so i replaced it. then somehow my problem disappeared ! no more lights or codes.
Parked it for a month and took it out this week, the arm worked for 2 minutes and then stopped !
ACS light on YAYYYY ! impossible to move the arm and the front window was on, sooooo, i had to use the manual lever to bring the arm down. i tried to shut it multiple times but still the same problem !
one thing i noticed different is that as soon as i turn the key to the "on" position, one of the actuator makes a noise like its calibrating for a quick second and then the noise stops.
My codes are 32-49 and 32-65. i've red that the wire #1500 should have around 5V +/_ 0.25V but when i unplug it fron the ACS control box, i have a 7.5V....i've been reading the threads from left to right without any success to my problem. i like fixing everything myself and understand the problem rather then bringing it to the shop. Im in france, (im an american that moved oversea) shop rates are ok compare to the us, but still, i'd like to figure that one out and if someone would be willing to help, maybe it will serve for futur members !
