General description:

The start/stop system is used for reducing fuel consumption

by automatically switching off the engine when the vehicle is

stationary and automatically starting it when the driver wants

the vehicle to move on. The start/stop mode is automatically

activated when, after moving off, the vehicle is driven for about

four seconds at a speed of at least 3 km/h. In towing mode, the

start/stop system is switched off.

Fault detection and fault display:

The start/stop system as a function is integrated in the engine

control unit -J623- software.

The engine control unit -J623- features self-diagnosis to facili‐

tate fault finding.

For fault finding, use the systems described in chapter “Vehi‐

cle diagnosis, testing and information system” in “Guided Fault

Finding” mode ⇒ page 269 .

Battery recharging or jump start on vehicles with start/stop sys‐

tem:

When recharging or jump starting vehicles with start/stop sys‐

tem, note the following: first connect charging cable to battery

positive terminal then body earth. This ensures that the battery

monitoring control unit is not bridged. Charging the battery di‐

rectly on the negative terminal causes the battery monitoring

control unit to be bridged. The battery data is not collected by

the battery monitoring control unit during the charging process.

Then, the values concerning the battery state and saved in

the data bus diagnostic interface would not correspond to the

values of the charged battery.

Replacing battery on vehicles with start/stop system:

Because of its higher deep-cycle resistance, only an absorbent

glass mat battery is used as a starter battery instead of the

normal lead battery in vehicles with start/stop system.

In case of repair, note correct part number designation in ETKA.

The modified components for the start/stop system have no

special markings. They do not differ externally, or hardly, from

standard components.

On vehicles with the start-stop system, the “Parametrising bat‐

tery after replacement” procedure has to be performed after the

4.4.1

General description - voltage stabiliser

Note

The voltage stabiliser -J532- has been installed until the end of

2016.

Role of voltage stabiliser:

Voltage dips occur in the onboard supply system each time the

engine is started due to the high current draw of the starter.

4. Start/stop system

Amarok 2011 ➤, Amarok 2017 ➤

Electrical system - Edition 12.2020

To prevent any failure in the infotainment components and the

dash panel insert when the engine is restarted, the voltage

supply to the infotainment system and the dash panel insert is

protected by means of voltage stabilisation. To do this, terminal

30 is fed through a DC/DC converter during the starting process

and the voltage is stabilised at 12V. The DC/DC converter is

only active during the actual starting process (terminal 50). For

other times, the converter is bridged with the aid of an internal

relay and supply comes directly from the onboard supply sys‐

tem (terminal 30).

Effects in case of voltage stabiliser failure:

When the starter is operated and the voltage supply is insuf‐

ficient for devices like radio, radio navigation system or tele‐

phone they will perform a reset. If, in start/stop mode, the men‐

tioned electrical consumers are identified as causing a reset for

each motor start, this indicates a defective voltage stabiliser.

Direct entries concerning malfunction of the voltage stabiliser,

e.g. in the event memory of the diagnostic interface or the on‐

board supply control unit, are not done at present. If radio, radio

navigation system and telephone units have failed together, first

check fuse of voltage stabiliser.
