A BT CAN key & an untrained person can be a very dangerous combination with a RRE.
Injury or even death is a possibility if you go in to the service menus & activate the wrong service function at the wrong time!

Read the service manual or ask a RRE trained technician what the hidden service functions do BEFORE thinking about plugging a BT CAN key in to a RRE.

2:434 is " +15V for external sensors over +16.5V "
Specifically mentions conductor 29 being possibly shorted to a conductor with higher voltage than 15V.
Maybe re-check your broken wire repair and/or check that mast sensors B18 and B19 are not damaged and function correctly.
Do you have a CAN Key??? It's available as a service part and allows you to monitor sensors etc. as they perform switching etc. It will also allow a person to completely scramble the truck's brain, so it must be used extremely cautiously!! Suggest you have a conversation with your local dealer/tech soon, so as to get the correct CAN key if you don't have one.

You really need a service manual at the very minimum.

Hi guys.
Thanks for answer, but I have another one error 2:434. I have a description, but I don't find a source of problem. I repaired broken wire from plug X38 to sensors on mast, but error still back.

If the radial bearing has failed - order a new genuine BT gearbox, you get a free radial bearing with it.

For what the radial bearing costs & labour involved it makes sense to spend a little extra & fit a complete gearbox.

NOTE: New gearbox requires an oil change after first 1k hours - 75w90 FULLY synthetic gear oil required.

5:181 is now 5:385 in the newer lifts.
In my manual 5:181 is" Signal from steer angle transducer is 180 degrees incorrect"
I had this problem ( read above) and it ended up that the radial bearing was worn badly, and chewing the end off the steer angle sensor.
In a nutshell check your steer angle sensor for damage. Like someone took sandpaper to the sensing surface. It's hard to see but... also check the wiring to it.
If your machine is at the 12,000 hour area - you may have final drive issues.ie: worn radial bearing.

Hello,
And can you tell me what is the error 5:181/ 5:385?
I do not have this in the manual.

Just to follow up on this problem... when I got the old final drive out of the unit, I noticed a couple of things.
The input to the drive is a female spline hub and the splines were worn down to just a sliver left, she wasn't going much further. The male spline on the traction motor which drives this was worn a little but must be much harder material.
This is at the 14,000 hour mark approx.
This play between the splines can actually be readily noticed by a "clunk" when plugging.
So if you are hearing a clunk at this hour mark you should be getting a gearbox ordered up.
Also - the input bearing (not the radial bearing) that is supporting the female spline hub/gear, was almost seized and was locking up at times.
When this bearing locks up, the traction motor rotational inertia/torque can actually overcome the holding action of the steer motor assembly and "whip" or throw a very drastic steer action - very suddenly causing the truck to veer wildly and unexpectedly!!
Just throwing this tuff out there - maybe will help others.
Thanks to all for your inputs!!

Will do. 75W90 full synthetic @ 1000 hour mark.
Thanks.

If you fit a new transmission to an RRE then remember to change the gearbox oil after its done 1k B hours as per BT recommendation.

75w 90 fully synthetic gear oil.

I have convinced myself to change the whole transmission out. As you say, the radial is part of the assembly anyway, and to change only the radial and have a different transmission issue down the road makes no sense. A new assembly should easily get the machine to where it goes out for pasture when the original got it to almost 13K hours.
I started this post convinced it was an electrical problem, finally took the blinders off and saw the light.
Thanks everyone for the help!!

The radial bearings on RRE where upgraded in the past & should now last longer.

Free radial bearing when you buy a new transmission.

4.5 hours is the book time to change it.

Changed radial bearing on every bigger 180-250 rre with 12000+ hrs
I look after, about six, tell me about not getting younger

Oh yeah, was going to mention also unit has almost 13,000 hours. It's a lot like me - not getting any younger!!

Finally following jim s advice and had a closer look at the sensors. You have to look really, really close but the end of the sensor which sits above the ring gear has tiny grooves worn in them. All of them that have failed. I took a paint pen and painted the end of the sensor, re-installed it and did a couple of complete turns, the paint was scraped right off the sensor. There is really no discernible play in the radial bearing, but there must be enough that the clearance is gone between it and the sensor. Looks like I will be changing out the radial bearing and possibly the whole final drive. Wheel seal is leaking and getting a fair bit of clunking/backlash when changing directions. Hopefully that will fix it !! Thanks all for the help!!

The 1st "new" 225569 steer angle sensor made it 34 hours before code 5:184 returned. Dealer tech updated software, installed 2nd "new OEM" sensor and this time it went 38 hours before code mostly 5:385 showed back up, along with a 5:182 and 5:183, and 5:184. But mostly 5:385 in history. Not sure where to go from here? Is it possible the MCU can be the cause? I'm confident if I put in another new sensor that it will run again, but for how long? There has to be something else amiss.
