6.6.1 Retrofitting
Fig. 6-18 v board: Cutting conductors, inserting HA board and soldering it on
Procedure
– Cut the printed conductor (1) and remove the SMD component.
– Remove the soldering points (2) by suction.
– Put the HA board 4 on the v board with the strips facing down and solder it on.
– Solder the green and brown wires on the HA board.
Remark
If rear axle transmission is activated, the vehicle's modified characteristic
coefficient imp/km must be adjusted to the actual imp/km by carrying out a two
speed axle calibration adjustment. When doing this, please remember that,
depending on the vehicle type, switchover is controlled either by the positive or
negative potential. The additional equipment is no longer available with µP units!
