Dps-Circuit Card A10 - Valtra 6000 Workshop Manual

31. Autocontrol 2.2 / 2.3
C. DPS---circuit card A10
Pins 1 and 2: Current to DPS solenoid valves
(Y4, Y6), battery voltage (12 V)
Pin 3: Continuous ground
Pin 4: voltage of 12 V via ignition switch and
fuse F22.
Pin 5:
12 V, when foremost DPS button is de-
pressed. Otherwise unenergised.
Pin 6:
12 V via fuse F22 and ignition switch
Pin 10:
12V, when head lights on, otherwise
unenergised
Pin 11: continuous current via fuse F11
(12 V)
Pin 12: when parking brake is applied, pin 12
is earthed.
Pin 13: earthed, when engine is stopped
Pin 14:
12 V, when rearmost DPS button de-
pressed. Otherwise unenergised.
Pin 15 and 16: In transmissions 460 and 650
wire is connected to pin 15 and
in transmission 300 to pin 16
(12 V).
Pin 17, 18 and 8: Signals to DPS pilot lights
(12 V).
Position of connectors
X1: In fuse box
X4: In fuse box
X6: In fuse box
X11: In cab roof
X13: on support plate in lever console
X19: Socket on the cab wall on the RH side
X26: White connector on the rear face of the instrument
X27: Blue connector on the rear face of the instrument
S23: DPS push button connector at the lower end of the
gear lever
X23: DPS extra push buttons connector at the lower end of
the gear lever
Note! Electric signals into the circuit card A10 can be
measured from pins of 18---pole connector when the
ignition is switched on. Measure voltages with different
switch positions (see picture above). If the measured
value is faulty, check wires, switches and connectors
which affect the circuit in question.
From pins 1 and 2 of the circuit card is sent current to
the DPS solenoid valves Y4 and Y6 (see +/0 diagram in
the picture above).
If no signal is sent to the solenoid valves, although other
parts are OK, the fault lies in the circuit card.

Pins 7 and 9 not in use
X23= connector for extra push buttons
GR1= earth point in the rear part of the lever console
GR5= earth point on the cab front wall
Note! Position of various components and wiring diagram are
shown under code 310.
V1=diode housing of solenoid valves. In AC 2.3 diode housing
V3 is for solenoid valves.
On pins 1 and 2 can be measured voltage value when
the current is switched on and the connector is faste-
ned to the circuit card A10. When measuring on the
lower pins, be carefully not to short circuit the poles.
Measure rather on the wire side of the connector.
From pins 17, 18 and 8 are sent signals to the DPS
pilot lights (12 V) in the dashboard instrument. When
the DPS push buttons are pressed (ignition on) the
pilot lights in the instrument must light up in a correct
order. If the pilot lights have malfunctions, check the
lamps and wires from the circuit card to the lamps. If
the lamps and the wires are OK, but malfunctions oc-
cur, change the whole circuit card A10.
