CAUTION
Replacing battery housing:
The work must be performed by a high-voltage expert (HVE) or high-voltage technician (HVT) who has received
additional training (Replacing A3 etron housing in accordance with campaign instructions).
If moisture is found in high-voltage battery:
Work must be performed by high-voltage expert (HVE).

Safety Precautions When Working ON the High-voltage System (additional information
is also available in the ELSA Repair Manual)
DANGER
High-voltage can cause fatal injury


The voltage levels in the high-voltage system constitute a safety hazard. Danger of severe or fatal injuries
from electric shock.



Persons with life-sustaining or other electronic medical devices in or on their body must not perform any
work on the high-voltage system. Such medical devices include internal analgesic pumps, implanted
defibrillators, pacemakers, insulin pumps and hearing aids.



The high-voltage system must be de-energized by a suitably qualified person.

DANGER
There Is a Risk of Explosion Caused by Cooling System Leaks in the High-Voltage Battery. This Can
Cause a Buildup of Explosive Gases in the Battery Housing.


Explosions May Cause Severe Bodily Injuries.



Loss of coolant indicates there could be a coolant leak internal to the high-voltage battery housing.



If the indicator lights for “coolant level” and “high-voltage battery error” turn on, move the vehicle into the
open air into the defined separate parking area.



Notify the high-voltage expert (HVE).

WARNING
Risk of injury - motor may start unexpectedly
It is difficult to determine whether the drive system of an electric vehicle or hybrid vehicle is active. Moving parts can
trap or draw in parts of the body.
CAUTION
Risk of damage to high-voltage wiring
Incorrect handling may result in damage to the insulation of high-voltage wires or high-voltage connectors.


Do not support yourself on high-voltage cables or connectors.



Never prop tools against high-voltage wiring or high-voltage connectors.



Never bend or kink high-voltage wiring.



Observe the coding of the high-voltage connectors when joining them up.

Repair Instruction
Section A - Check for Previous Repair


Enter the VIN in Elsa and proceed to the
“Campaign/Action” screen.

TIP
On the date of repair, print this screen and keep a
copy with the repair order.




The voltage levels in the high-voltage system constitute a safety hazard. Danger of severe or fatal injuries
from electric shock.



Persons with life-sustaining or other electronic medical devices in or on their body must not perform any
work on the high-voltage system. Such medical devices include internal analgesic pumps, implanted
defibrillators, pacemakers, insulin pumps and hearing aids.



An Audi high-voltage technician (HVT) or an Audi high-voltage expert (HVE) must de-energize and
re-energize the high-voltage system.

CAUTION
Risk of damaging the high-voltage cables.
Incorrect handling can damage the insulation of the high-voltage cables or high-voltage connectors.
NOTE


Removing the high-voltage battery can be performed by a High-voltage Trained (HVT) technician.



The High-voltage Expert (HVE) must be informed if the system cannot be de-energized.

Test plan text: Does the electrical shock protection
remain on all high-voltage components after deenergizing the high-voltage system?

Pay close attention when the
008C_Isolationswiderstand_HV_Batterie_mess
en_93D2 de-energization test plan step asks
about shock protection.
This step refers to the shock protection installed on
the e-machine or the Electric Drive Control Module
-J841- prior to removing the battery. It does not refer
to disassembling the high-voltage battery.
Disassembling the high-voltage battery will be
performed while wearing PPE.

The electrical shock protection on the high-voltage
components remains if you are not working on the
e-machine or opening the cover of the Electric Drive
Control Module -J841-.
