thank you very much.
ok i will check
m4f is an incorrect start, either driving direction is not in neutral, or accelerator pedal and or brake pedal is not in rest-position before (seat switch) and keyswitch are activated.

If the truck is active, also the seat switch must be closed before accelerator and/or direction switch is closed, if not> truck will give incorrect start (as the name implies).
Same goes for when the truck is in SRO Static Return Off, all inputs must be neutral.

PDF SBR e12 and e4 are nc.
but The code is still on the dyspley.

and MF4
How to make sure that the Accelerator is damaged.
Accelerator modell MTF13 comesys
PDF SBR switch is related to the battery-door switch.

NC switch on right side of machine on battery-door.
To prevent driving when battery-door is openend.
Very often the wiring of this switch is getting between door and chassis, resulting in broken wiring.

For testing purpose, just remove switch, connect the 2 wires so master will see this as a NC contact.
If unsuccesfull, wiring is broken.

Connection on pumpcontroller E12, wire 68 switches to E4 common wire 222 (A trough E)

Good luck!

MF4= wrong traction request sequence

M=master
4F = incorrect start.
After switching on keyswitch either driving direction is not in neutral or acceleration pedal is not in zero position.

Calibrate acceleration pedal if problem exists.
