42. CONNECTOR SOCKETS FT, DIAGNOSTIC CONNECTOR, ALARM CONNECTOR
DIAGNOSTIC CONNECTOR (A021)
The diagnostic connector is installed on the
left-hand side in the central cabinet. This is the
connector to which DAVIE is connected. After
the contact has been activated, the supply
voltage for DAVIE is applied to pin 1 through
fuse E053. Pin 2 is connected to earth. The
remaining pins are meant for the communication
with various systems and are connected to
those systems.

24V CONNECTOR (A042)
Pin 1 of the 24V connector (A402) is
connected directly to the supply voltage
through wire 1000 and fuse E026.
Pin 2 is connected to earth.
ABS CONNECTOR (A005)
Pin 1 of the ABS connector (A005) is
connected directly to the supply voltage
in front of the contact through wire 1119
and fuse E043.
Pin 2 is connected directly to the supply
voltage behind the contact through fuse
E172. This voltage also serves to feed
the ABS unit.
Pins
3+4 are both connected to earth.
Pin 5 is connected to pin 7 of the CWS-2 unit
(D853) through wire 3428.
FT TRAILER CONNECTOR (A002)
Pin 1 of the FT trailer connector (A002) is
connected to earth. If a connection is
made between contacts 2 and 1
(rear/side marker and parking lights
position) with the lighting switch
(C622), a voltage is applied to contact
85 of relay G000 through fuse E084,
wire 1101, switch C622 and wire 2100.
The relay is activated and a voltage is
applied from wire 1000, contacts 30
and 87 (from relay G000) through fuses
E000 and E001 to pins 2 (through wire
2102) and 6 (through wire 2103)
respectively.
Pin 2 switches the left-hand rear light.
Pin 3 is connected to the CTE-2 unit (2/232)
(left direction) through wire 2008.
Pin 4 is connected to relay G036 (brake -light
relay) through wire 4601.
Pin 5 is connected to the CTE-2 unit (30/232)
(right direction) through wire 2009.
Pin 6 switches the right-hand rear light.
REAR FOG LAMP / BACK-UP LIGHT CONNECTOR (A003)
Pin 1 is connected to earth.
Pin 3 is connected to the supply voltage after
the contact has been activated and the
gearbox is in reverse gear. The voltage
is applied as follows: through fuse
E016 (wire 1217), backup switch E501
(wire 4591) to pin 3.
Pin 5 (connector A003) is connected directly
to the supply voltage through fuse
E048 and wire 1113.
Pin 7 (rear fog lights) is connected to the
supply voltage through fuse E010,
relay G005 and wire 2152.
DIAGNOSTIC CONNECTOR SAE CUMMINS (A031)
Pin A is connected directly to the electronic
unit DAF Cummins interface (D804)
(35/334) and the electronic unit
Cummins Celect (D805) (27/335)
through wire 3048.
Pin B is connected directly to the electronic
unit DAF Cummins interface (D804)
(34/334) and the electronic unit
Cummins Celect (D805) (8/335)
through wire 3047.
This diagnostic system is completely different
from the DAF diagnostic system. DAVIE will not
respond when connected.
ALARM SYSTEM SOCKET (A040)
Pin 1 is connected directly to the supply
voltage in front of the contact through
wire 1114 and fuse E0108 (wire 1000).
Pin 2 is connected to the direction indicator,
front left (C014), side direction indictor,
left (C016), direction indicator, rear left
(C018) and the electronic unit CTE-2
(D550) (4/232) through wire 2006.
Pin 3 is connected to the direction indicator,
front right (C015), side direction
indicator, right (C017), direction
indicator, rear right (C019) and the
electronic unit CTE-2 (D550) (31/232)
through wire 2007.
Pin 4 is connected directly to the control
switch for interior step lighting, door
switch on driver’s side (E514), the
stepwell lighting, driver’s side (C062),
the electronic unit CTE-2 (D550) and
the lighting buzzer relay (G235).
Pin 5 is connected directly to the stepwell
lighting, co-driver’s side (C063), the
interior lighting switch, co-driver’s side
(C686), the control switch for interior
step lighting, door switch on co-driver’s
side (E515) through wire 2609, while
the interior-lighting diode prevents
feedback to the co-driver’s stepwell
(D708).
Pin 6 is connected directly to the cab-lock
control switch (F009) through wire
3412 and by means of a cab lock
connection (cab without air suspension)
(G719) to the electronic unit CWS
(D582) (20/215) through wire 3492. If
the cab is air-suspended, wire 3412 is
also connected to pin A2 of the
electronic unit of the cab
air-suspension.
Pin 7 is connected directly to the generator
integrated voltage regulator (A502)
(D+) and to lighting relay D+ (G107). At
the same time pin 7 is connected
directly to the lighting buzzer (B242)
and to the electronic unit CWS (D582)
(12/214).
Pin 9 is not connected.
Pin 12 is connected to earth.
