Fig. 3.84. AKP electronic components: 1 – control unit of automatic KP; 2 – hydraulic module of management; 3 – cover of the drive of inclusion of transfers; 4 – Tiptronic sensor; 5 – electromagnet of blocking of the automatic transmission selector; 6 – diagnostic socket; 7 – the sensor for system of automatic control of speed; 8 – 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); 9 – power supply relay plug 87/of the relay of automatic KP; 10 – indicator of position of the automatic transmission selector; 11 – Kick-down sensor; 12 – stoplight switch

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.

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.

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).

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).

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).

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.

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.

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.

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.
