Guten Abend,
Wir besitzen einen Yale MS 15 x, beim einschalten zeigt er den Fehlercode 21552.Der Hochhubstabler
fhrt und der Freihub funktioniert aber der Hubmast fhrt nicht hoch.Knnten Sie mir helfen? Wenn die Stecker fr den Hubmast beim Start von der Platine abgezogen werden, zeigt sie keinen Fehlercode an, wenn Sie dann aufgesteckt werden kommt der Fehler 29457.
Mit freundlichen Gren B..y
The Motor Control Module (MCM) monitors the rail pressure and when rail pressure deviation is greater than 200 bar for eight seconds, the MCM sets the code. This fault can occur due to the conditions listed below:
The VSM is seeing 2 directional inputs at the same time. Check the wiring at the VSM connector. If it is OK, you probably have a defective VSM or it needs to be reflashed. Check to see that there is a static strap on the truck.
I have a 2010 hyster H155ft Serial number J0067G02622h. Its throwing a 524240-4 code, which i found was the washer pump drive command OORL. Curious to see if anyone else has had this issue and what this fix was. Thanks
DTC 12576
Motor Voltage Not OK
DC Bus charging timeout.(Usually caused by low battery voltage or poor connection.) you can open in motor circuit or bad motor controller or bad wiring to motor controller from motor
I have a code on a Yale MSW040SFN24TV087 the code on the screen shows a wrench and AL-06. None of the functions work, when the machine is first turned on it shows no codes until you try to operate it and just clicks and pops up a red light with the cod on the screen. Any info helps
Error: AL06
What the issue is: Traction and hydraulic functions not working
Cause of Problem: Damaged connection to traction motor; traction motor armature resistance is too low; field wires are loose or damaged; motor field winding is shorted or too low.
What to Do: Check the electrical connection between traction motor, field wires, and controller; check traction motor armature for shorts; check motor field resistance and correct if not between 0.5 and 1.5 ohms; check contactor coil for resistance of 52 ohms
POSSIBLE CAUSE
A. SENSOR GROUND OPEN CIRCUIT
B. SENSOR SIGNAL SHORTED TO SENSOR SUPPLY
C. SENSOR SIGNAL SHORTED TO BATTERY
D. SENSOR FAILURE
E. FUNCTIONAL FAILURE IN CONTROLLE
The code can indicate a loss of communication between the system manager and the pump controller through the CANBUS.
Check your connectors at the VSM and the hydraulic controller.
The wires you need to check are the green/ yellow twisted pair. There could be a failure in one of the controllers also
Hello, I have a hyster 2.5 elevator, it does not give a start signal, co 13 and co 26, I would like to know what they are, how I could solve it, if I can reset it, the machine raised a fault in the battery, a jumper was made to start it, thank you very much in advance, greetings from Argentina
I have the error picture on my yale erc050. Its a picture of the top being lifted. But it isnt. As if the seat is open for charging. But it isnt. It is intermittent. Where is the sensor located so i can check it up??
There are a few possible causes for low oil pressure that would lead to this code appearing. It could be a faulty oil pressure sensor or wiring, a short in the sensor circuit, or the oil pressure sensor itself going bad.
The engine harness connecting the oil pressure sensor could be the reason behind error code 100-4. It is possible that the connector has pushed back or expanded pins, bent or broken pins, or corroded pins. These issues can disrupt the connection between the sensor and the engine harness, causing the error code to appear.
Another potential cause of error code 100-4 is moisture in or on the connectors connecting to the oil pressure sensor. Moisture can interfere with the electrical signals being transmitted through the connector, leading to an erroneous reading from the oil pressure sensor. This can trigger the error code and indicate a problem with the engine harness.
Determining the correct pin to measure resistance in an engine harness can vary depending on the specific vehicle or equipment model. However, there are general steps you can follow to identify the correct pin:
So the first step when it comes to troubleshooting fault code 100-4 is to turn the key switch OFF and disconnect the engine harness from the oil pressure switch. And then Inspect the oil pressure switch and the engine harness connector pins for the following:
Moisture in or on the Connector: Moisture can cause short-circuits or corrosion, both of which can interfere with the electrical signals passing through the connector. This can result in the ECU receiving no signal or a faulty signal, which may trigger an oil pressure error.
Now a short to ground means somewhere along that wire path electricity is leaking straight to the body of the forklift rather than following the route to the computer. Could be a fray in the wires, the sensor itself gone kaput, or a loose connection letting the current sneak away.
The fix here is to track down the short circuit. Check connections are tight, wires intact, and the sensor itself is in working order. The computer needs good intel to manage the engine properly. Once you get that oil pressure data flowing right again, the computer can relax and let the engine run as it should.
Firstly, the oil pressure sensor itself might be malfunctioning or have completely failed, resulting in the transmission of an incorrect low voltage signal. Additionally, there could be problems with the wiring connected to the oil pressure sensor, such as a short circuit or disconnection, causing a disruption in the voltage signal.
However, it is also essential to recognize that the engine could genuinely be experiencing low oil pressure. This can stem from various factors, including a low oil level, worn engine components, or even a faulty oil pump.
There are several factors that can contribute to the damage or loss of these seals. For instance, regular wear and tear over time can cause deterioration, especially if the forklift is subject to demanding working conditions or insufficient maintenance. Additionally, accidental impact or mishandling during maintenance procedures can result in the seals becoming damaged or displaced.
For some, the resolution might be as simple as replacing a worn-out harness that has seen better days. For others, it could involve tracing and repairing short circuits that are causing havoc in the electrical system. And then there are times when the oil pressure sensor is the culprit.
How did you resolve the fault code 100-4? Was it a matter of swapping out the harness, or did you find yourself untangling a web of electrical shorts? Or perhaps it was the oil pressure sensor that needed your attention. Share your experiences and solutions in the comments below.
There are various troubleshooting methods, depending on the underlying issue causing the error 853 on Crown pallet jacks. Some fixes like repairing short circuits in cable connections are quick, while replacing faulty potentiometers requires more technical work. The complexity of repairs for code 853 ranges from fast fixes to more intensive part swaps, so diagnosing the specific problem is key before beginning any troubleshooting.
These electronic parts are critical for smooth, variable speed control on modern Crown pallet jacks. Older jacks had simple switches, but the twist grip allows precise speed regulation. Losing this makes the jack frustrating to operate.
5). Once the new throttle card is installed, reassemble the switch cap. With any luck, this should resolve that error code for good. Double-check that the throttle and speed control are working properly before putting your Crown pallet jack back into service.
The FU3 fuse is typically located on the control panel or near the battery on the Crown Pallet Jack. It protects the control circuit from power surges and shorts. If the FU3 fuse is blown, it will cut power to the handle and prevent the pallet jack from operating properly, which can cause error code 853.
3). If the FU3 fuse is blown, replace it with an identical new fuse with the proper amperage rating. A blown fuse indicates there may be an underlying short or power issue in the control circuit that will need to be diagnosed and repaired.
CA205-3 and CA205-2 refer to specific pins on the motor controller circuit board that help regulate power to the electric drive motor. The positive signal wire provides power to CA205-3 while the B-NEG wire connects the motor to the ground via CA205-2.
To check for open or shorted wires, first visually inspect the length of the wires for any obvious damage, cuts, or abrasions in the insulation that could cause a short. Use a multimeter set to continuity mode to test each wire end-to-end for continuity. If you find a break in continuity, that indicates an open wire. You can also use the multimeter to check for shorts between the wires or from each wire to a ground point.
Make sure to check down by the knuckle/pivot point for any wires that may have rubbed through. Also, spray some DeoxIT Gold on all the connectors on the circuit boards. DeoxIT is a contact cleaner, lubricant, and anti-oxidizing solution that can help improve electrical connections. After doing that, recalibrate and see if the code clears up.
