Hi there
Happy New Year to all.
I have been asked to look at 3 trucks at a customers workshop, which have the 3 DC shunt controllers MP1514 in the back.
Each one has no steer but no error codes on the dash. Traction and hydraulics work but just no steer.
The controllers have been changed, the steer motor has been changed.
The customer has tried adjusting the truck length options, resetting the parameters.
We just cannot understand and get to the bottom of the issue.
Has anyone come across a similar problem? Is this a common fault on these 4 wheeler trucks?
Showing items 1 - 8 of 8 results.
HI Nemanja
Ok ill get the serial number off it next time. We managed to get it sorted, but would be nice to have the correct wiring diagram.
It was a combination of steer parameter option 1 and a faulty steer sensor.
Thank you
Write data of truck,and I will try to find you wiring.
Hi there
the second one did not work by setting the steer parameters option 1. Can anyone recommend any other suggestions?
Thank you for the comments and emails.
it was the steer option 1 parameter that needed altering, wouldn't have got to the bottom of it without the help from this forum. Hopefully the other 2 have the same issue :)
you, get the serial number of the equipment.
The steer unit is the left controller. This controls hydraulics too, which is working fine.
We did change the interface cards, this made no difference. Could there be a trigger input or an output from the interface card to the mp1514 and could this wire have broken? a wiring diagram would be helpful if someone could supply please.
I'm an EFG with equipment problems in the steering motor, have checked the engine?
