High-voltage system - General information Repair Manual

The new all-wheel drive Touareg is a versatile high-end vehicle with innovative technical solutions, excellent driving dynamics and a high level of comfort, as well as a striking exterior and interior design.

Structurally, it is based on the modular MLB platform with a longitudinal layout of the power unit. High dynamic performance, excellent traction and cross-country ability are provided by highly efficient turbocharged engines and an 8-speed automatic transmission with an integrated transfer case with a self-locking center differential that distributes power flow between the front and rear axles.

The new central control unit ensures that the following auxiliary systems, dynamics and comfort control systems work together:

– a night vision system that recognizes in the dark, for example, pedestrians and animals;

– traffic jam/roadwork assistant, which provides partially automatic steering, lane keeping, acceleration and braking up to a speed of 60 km/h;

- Intersection assistant, which reacts to cross traffic;

– active steering of all wheels;

- roll stabilization system with controlled electromechanical stabilizers;

– Matrix LED headlights low and high beam;

- Projection display.

The 12.3" digital instrument cluster and the 15.3" Infotainment display are combined into one single Innovision Cockpit.

The new model received a combined body made of aluminum and steel, which, despite the increased length and width, has become 100 kg lighter than the predecessor model.

The on-board network of the VW Touareg 2019 will for the first time use a 48 V sub-network designed to power the electromechanical roll stabilization system. The on-board electrical system in the Touareg therefore consists of two parts:

– on-board network 12 V

– new 48 V on-board subnet

On Touareg versions without roll stabilization, the 48 V onboard power supply components are not installed.

Onboard network 12 V

Only one AGM battery (Absorbent Glass Mat - absorbent fiberglass filler) is installed with a capacity of 68 to 105 Ah.

The 12 V battery is charged by a generator with a charging current of up to 250 A, depending on the configuration.

The main fuse box (SL fuse box) and the N253 battery disconnect device igniter are installed on the positive battery terminal. When the igniter of the N253 battery disconnect device is triggered when the restraint systems are activated in the event of an accident, the starter, alternator, glow plugs and radiator fan are disconnected from terminal 30.

At the negative battery terminal there is a control unit for battery monitoring J367.

48 V subnet

The need for a sub-network with a voltage of 48 V arose due to the presence of a powerful consumer of electricity - an electromechanical roll stabilization system. The 2019 VW Touareg will be the first Volkswagen model to be equipped with this system.

In addition to the already known 12 V components, some additional components are installed on the Touareg 2019, forming a 48 V subnet. First of all, this is a 48 V / 12 V voltage converter, as well as an on-board storage capacitor. The voltage converter provides both roll stabilization control units J924 and J1096 (48 V consumers) with a constant voltage of 48 V.

The storage capacitor stabilizes the voltage in the 48 V subnet in case of short-term increases in electrical power consumed by the 48 V components.

48 V voltage consumers must not be connected to ground via terminal 31. For this, a separate ground connection terminal - terminal 41 - is now provided in the 48 V on-board subnet.
