Control unit of automatic KP

Fig. 3.85. Control unit of automatic KP


Installation site: the control unit of automatic KP is fixed on a back part of KP directly on the hydraulic module of management (fig. 3.85).
The following elements are integrated into the control unit:
A – sensor of frequency of rotation of an output shaft of KP and sensor 2 chvrashcheniye of an output shaft of KP;
B – sensor of temperature of gearbox oil;
C – multifunctional switch;
D – sensor of frequency of rotation of an entrance shaft of KP;
E – sensor of 1 hydraulic pressure of automatic KP;
F – sensor 2 of hydraulic pressure of automatic KP.

Hydraulic module of management

Fig. 3.86. Hydraulic module of management


Installation site: the hydraulic module of management is screwed on a back part of KP. Directly on the hydraulic module of management the control unit of automatic KP (fig. 3.86) is screwed.
A – Shtekerny socket of the regulator of pressure of 1 automatic KP.
B – Shtekerny socket of the regulator of pressure 2 automatic KP.
C – Shtekerny socket of the electromagnetic valve 1.
The following valves are integrated into the hydraulic module of management:
– regulator of pressure of 1 automatic KP (electromagnetic valve of coupling);
– pressure regulator 2 automatic KP (electromagnetic valve of the transfer relation);
– electromagnetic valve 1 (cooling safety coupling / shutdown);
– coupling cooling valve;
– regulator of the minimum pressure;
– reducing valve;
– valve of management of coupling;
– the operating pressure regulator.

NOTE
Valves are checked by self-diagnostics.

Electromagnet of blocking of the automatic transmission selector

Fig. 3.87. Electromagnet of blocking of the automatic transmission selector


Installation site: the electromagnet of blocking of the automatic transmission selector is in the drive of inclusion of transfers (fig. 3.87).

Diagnostic socket

Fig. 3.88. Diagnostic socket


Installation site: the diagnostic socket is under the forward panel to the left of a steering wheel (fig. 3.88).

Switch of system of automatic control of speed

Fig. 3.89. Switch of system of automatic control of speed


Installation site: the switch of system of automatic control of speed is on the understeering switch (fig. 3.89).

Indicator of position of the automatic transmission selector

Fig. 3.90. Indicator of position of the automatic transmission selector


Installation site: it is integrated into a combination of devices (fig. 3.90).

NOTE
The indicator of position of the automatic transmission selector can be replaced only together with a combination of devices.

Power supply relay the plug 87/of the relay of automatic KP and the relay of blocking of a starter and headlights of a backing (to 10:04 g) or the relay of blocking of a starter (from 11:04 g)

Fig. 3.91. Power supply relay the plug 87/of the relay of automatic KP and the relay of blocking of a starter and headlights of a backing (to 10:04 g) or the relay of blocking of a starter (from 11:04 g)



Installation site: on the block of the relay of the assembly block of the water taking away box.
Giving of food via the plug 87 is carried out through:
1 – the relay of automatic KP – only on cars from 2,4 l the petrol engine;
2 – Motronic power supply relay – on all other cars with the petrol engine;
3 – power supply relay the plug 30 – on cars with the diesel engine;
4 – the relay of blocking of a starter and headlights of a backing (to 10:04 g) or the relay of blocking of a starter (from 11:04 g).

NOTE
On cars from 11:04 g control of headlights of a backing is exercised on the CAN tire.

Stoplight switch

Fig. 3.92. Stoplight switch


Installation site: the switch of a stoplight is in pedal knot (fig. 3.92).

NOTE
For ensuring reliability of installation the switch can be installed only once.

Kick-down sensor

Fig. 3.93. Kick-down sensor


Installation site: in the module of a pedal of an accelerator (fig. 3.93).

NOTE
Function of the Kick-down sensor on cars with the petrol engine is performed by the sensor of provision of a pedal of an accelerator and the sensor 2 provisions of a pedal of an accelerator.
On cars with the diesel engine the Kick-down sensor is blocked with the sensor of provision of a pedal of an accelerator and executed as the switch.
