Hey guys, we have an FD25T-17 with 3 times flashes except the flashes on the display the truck works fine. According to the information I have it must be the switch of the handbrake. We've controlled it and also replaced the relais and controller but the problem is still on it. The seat switch and handbrake switch are working, when we leave the truck with the contact off without putting the handbrake on we get the alarm buzzer when we put the handbrake on the alarm buzzer stops. Can anyone help me with this problem? I don't have any further information (manual, electrical diagram or meaning of error codes) of this model.
Many thanks in advance
