Hello everyone Got a super n with a bunch of codes on the On board display Any idea what they are? Ride control stopped working also Could it be related?:Banghead Thanks Code #1 1020 #2 1003 #4 1002 #5 1019 #6 1009 #7 4045 #8 1021 #9 1018
The 1000 codes are generally basic codes which leads me to believe your problem is with 4045. 4045 is charge pressure is not detected when engine speed is above 700 rpm for 10 seconds. First thing to check would be wires and connections from trans. temperature sensor to trans. controller. If wires are fine your looking at replacing either the charge pressure switch or the transmission controller. Better hope the switch is the problem if not you will be paying some high dollars for the controller. Make sure it isn't under warranty.
ok thanks so would have you any idea what the other codes are for?
if you send me your email I think I can send the manual
Thanks for the code index Lot of things coming up about coolant And fuel temp machine runs fine maybe it's Just faulty sensors Anyone any idea why the ride control Isn't working All fuses are good
When considering the faults, you need to also compare the last occurrence hour meter value shown on each fault code screen with the current hour meter value. If the logged faults are many hours apart, then the historic code may not be relevant to your current condition. As you have high temp warnings for engine coolant, transmission oil, fuel temp, and possibly A/C, I doubt you have that many bad sensors. You should consider what was going on at the hour meter value listed for those faults. As for ride control, there are different types of ride control and you did not advise what model Super N you have. The wiring and controls are different. Is your Super N a tier 3 or tier 4a machine? If tier 4a, do you have auto ride control, or standard ride control? Another thing to consider is ride control is designed to not function in backhoe mode. Is your seat switch damaged and the vehicle thinks it is facing backwards?
Sorry it's 2011 tier 3 I don't think the seat switch is broken as The machine has that auto function When you spin around it returns the engine To idle if you were operating the backhoe Also my ms have ride control and they will keep the function On no matter what you are doing unless turned off Otherwise As for the codes they are only dated about 1 month ago Or 150hrs back I wasn't driving but no one Ever mentioned and problems??
Ok, if it is tier 3, then the seat switch is not involved with the ride control logic. There is also no electronics involved, just simple switch/solenoid electrics and hydraulic valving. I would suggest determining if you have an electrical or hydraulic issue. The first place I would check is if there is voltage at one of the ride control solenoids connectors on the vehicle harness. (engine off, key on, ride control switch on) If you are not familiar with the ride control valve, let us know and we can give you more detail. Be safe though as by definition, ride control can move the loader arm. If there is voltage to the valve, then the issue is either with the solenoid(s) or is hydraulic. If there is no voltage then work backwards to the switch and fuse panel as needed. As for the fault codes 150 hours ago. “There should be more to the story.” If they all occurred at the same time, I would definitely talk to who was running the vehicle and find out more. It would be unlikely that simultaneous sensor failures occurred, then fixed themselves, relating to over temp faults with the engine coolant, transmission oll, fuel temp, and loss of transmission charge pressure. The operator should have noticed something. For example, loss of transmission charge pressure would cause the transmission to stop working, and the operator would surely notice that. Also. do the operators generally work the machine in conditions that would cause the gauges to be ran in the yellow and red areas?
im not familiar with the ride control loader valve sorry,so far if checked the fuses which are good also noticed the return to dig feature is also not working not sure if they are part of the same circuit or not?? thanks for the replies by the way on another note the machine is not run hard or abused day in day out the harshest conditions would be the new england weather....
About the only thing I see in common between ride control and return to dig on your machine is the ground point on the RH side of the chassis in front of the rear axle. The absence of a good ground could also explain some of the fault codes in the list. It will be a single eyelet with multiple wires and bolted to the chassis. Check that connection to insure it is a good, clean, and tight. Also make sure the ground boss on the chassis is not painted, so it would be good to take 5 minutes and fully remove that ground connection bolt, inspect, clean, and reinstall. If the above does not resolve, then check for voltage at the ride control valve. The ride control valve is underneath on the RH chassis in the middle of vehicle. It will be a small valve block with 2 solenoids on it and be close to the actual loader control valve and ride control accumulator. Here is a link to the Case parts store showing a image of the ride control valve. Also, a picture of same. http://partstore.casece.com/us/casepartstore/parts-search.html#epc::mr65753ar922640bi373031-2 Start by parking the vehicle in a safe manner including putting the loader bucket down on the ground. • Disconnect one of the solenoid connections. It will have a simple clip lock on the side of the connector that you can either raise with your finger or gently use a small screw driver to raise in order to release the lock, then pull the connection apart. • Connect a volt meter (reading 12v DC range) to one of the solenoid connectors on the vehicle harness(not the solenoid). The connector is 2 wire. Connect each of the volt meter wires to one of the harness connector terminals. • key on (do not start the engine), • turn the ride control switch to the on position, (be safe, remember by definition ride control can move the loader arm, keep you and volt meter away) • then see if there is 12v present in the wire harness and then chase as described in previous post.
The return to dig coil on the bottom of the spool has been notoriously bad on the SN series. Unplug the harness to the spool, use jumpers to battery...same side of machine. Connect the positive and negative, If it does not hold the spool I bet it's fried. The tier 4 units have been no better. The coil is easy to replace but costs an arm and a leg. The ride control coils have been somewhat of a problem as well. As for the error codes.....these things throw codes like no tomorrow. The code 1004 is common in cold climates it is hydraulic filter bypass. The thing with the codes on this unit is that they are set too easily. The duration that a sensor fails to register is too small, they need to open up the parameters a bit. It takes fractions of a second to set a code, unless it occurs several times dismiss it. Make sure the software is up to date too.
will check that out first thing tomorrow guys if it ever stops raining! anyone else think the previous models werent that bad overall.... series 2 m?? those are expensive little buggers do they go out often gggraham??
Well done everything you suggested checked wires All the way to the solenoid and found 2 broken wires I fixed them and thought all was well but still No joy... Maybe the solenoid is fried?? Called case out to take all look so we will see How it goes...
