- Red indicator: The test result is “negative”. One or
more modules must be replaced.

"Red" display result
- Grey indicator: There are no valid VALs. Additional
VALs must be created according to the following
procedure.
1. Creating and uploading a VAL
2. Charge up to 100% SoC via AC charge port.
3. Create and upload a second VAL after 6 hours of
downtime.
4. Create and upload a third VAL after 66 hours of
downtime.
5. Check analysis result again in PCSS.

If the final action "Re-programming ARB6 BMCe
software" is not available, the high-voltage
battery must be rechecked by means of a VAL
test after 60 days at the latest.

Invoicing for VAL check via WRS1 scope 2 or 3.
Replacing module via ARB5 recall/ and accompanying campaigns “Replacing cell block module”
Please submit the warranty claim for the campaign
in WWS via the assigned scope.
After replacing module:
If the final action "Re-programming ARB6 BMCe
software" is not available, the high-voltage
battery must be rechecked by means of a VAL
test after 60 days at the latest.

Open the front cover and connect a suitable battery charger, e.g., 90 A battery charger, to the
jump-start terminals and switch it on.

10 Open the door and position the driver’s key with the
back facing forward upright between the holding strips
in the rear drinks holder (emergency start tray) to
ensure a permanent radio link between the vehicle and
remote control.
11 Establish readiness for operation (switch on ignition).
Information
An active Internet connection with the PIWIS Tester must
be ensured. To log in using the PIWIS Tester, the technician
is required.
The PIWIS Tester must not be charged using the cigarette lighter!

Emergency start tray

12 Connect the PIWIS Tester to the vehicle communication module (VCI) via the USB cable. Then connect
the communication module to the vehicle and switch on the PIWIS Tester.
13 Create a Vehicle Analysis Log (VAL). Mark the Vehicle Analysis Log you have just created with the
attribute “Extra VAL” and return it using the PIWIS Tester after completion.
14 Charge the high-voltage battery of the vehicle on the driver’s side to 100% SoC via the charging port
with alternating current (AC).
To reduce the charging time, it is recommended that charging be carried out at industrial electrical
outlets, at E-charging stations, or at the wall box. Only charge the high-voltage battery at domestic
electrical outlets, provided no other charging option is available.
15 Start the charging process and note the time that 100% “Charging goal met at” is displayed in the
center console control panel.
The end time of the charging process is decisive for the creation of the additional Vehicle Analysis Logs.
Please ensure that the following intervals are observed. Failure to do so may result in delays or an invalid
evaluation.
16 After a charge state of 100% SoC has been reached, maintain an idling time of 6 hours and then create
a second Vehicle Analysis Log (VAL).
Mark the Vehicle Analysis Log you have just created with the attribute “Extra VAL” and return it using the
PIWIS Tester after completion.
17 After the second VAL, maintain a further idling time of 66 hours and then create a third Vehicle
Analysis Log (VAL).
Mark the Vehicle Analysis Log you have just created with the attribute “Extra VAL” and return it using the
PIWIS Tester after completion.
PAG feedback on analysis results is provided via a PPN update and provision of a VIN list with scope
allocation.

The data analysis yields a positive result (green PCSS display): The vehicle can then be handed
over to the customer. Continue to Warranty Processing, Scope 2-3.
The data analysis yields a negative result (red PCSS display): In rare cases, it may be necessary to
replace the cell block module. If this is the case, the VIN in the ARB5 campaign is transferred to one
of the accompanying campaigns.
VAL faulty/insufficient (yellow or grey PCSS display): In very rare cases, additional VALs may be
required.
