Q - Will the customer be informed of which updates and new functionality have been made after
OTA?
A - Prior to the update - when prompted with a request for installation, check under the (i) prompt
on the top right corner of the screen, then press “Read More” before initiating SW installation.
After the update – the customer can find information about latest SW on the support pages for
certain markets.
https://www.volvocars.com/intl/support => select your market => find “software updates”.
Q - Can we offer OTA to fix QB?
A - Yes, if the QB fix relates to SW.
Q - Can the customer view the Customer Letter (i.e. for a QB) in the car?
A - Yes, the same way as all other release notes - please press the “i” prompt in the center-display
and on the following screen, press “read more”, then the customer will be redirected to content
of the Customer Letter.
Q - Can the customer schedule the installation from the mobile phone e.g. using the Volvo Cars
app?
A - No.
Q - How can the customer know if the update contains a QB?
A - The customer will be notified in two ways:
1. Via email/mail.
2. Via message on the center display in the car.
Please note that the QB always has a unique ID-number e.g. QB-R/-S/-X followed by a 5-digit
number 12345.
Q - What SW will be sent via OTA SW update?
A - General SW updates and QB updates, if the QB does not contain any other action requiring a
visit to a workshop.
OTA will NOT handle Pre-Delivery Service SW installations, SW installations when replacing
ECU or SW for accessories (at least not for the time being).
Q - Will the OTA SW updates be downloaded to the car via the WiFi of the customers phone, or will
the car have a unique car SIM installed?
A - All cars with Google Automotive Services can be supported by OTA. They have an internal SIMcard supporting global roaming installed.
Q - Is the customer clearly informed about the disablement process during OTA installation?
And are they fully aware that the car will not be able to be driven during the installation period?
A - Disablement is part of initiating the OTA installation during the update of the car ECU’s.
Once an installation procedure has been initiated, the SW is being over-written, and the car will
be not be accessible for approximately 1.5 hours.
The customer is informed via an in-car message that the car needs to be locked and alarmed in
order to install.
Unlocking and entering the car will interrupt the installation.
The customer is made aware of this and approves this when choosing the install option on the
center display in the car.

So, it is essential that the customer and/or user carefully plan when they would like the
installation to commence, during a time the car can remain undisturbed, such as during the
night.
Q - Am I allowed or able to open the car during installation to retrieve something I urgently need
from the car?
A - It is NOT advisable.
By using your mechanical key, it is possible to unlock the car.
NOTE! The remote key fob is disarmed as part of the OTA process.
If a customer absolutely feels the need to accessing the car, they can do so using the mechanical
key, as the remote key fob is disabled.
NOTE! There is a risk that accessing the car may interrupt the SW installation, and in the worst
case scenario, may risk that the car cannot be used.
Q - Outside of warranty cases, is this SW free via OTA but charged for at the workshop?
A - This is valid at the moment of writing but may vary depending on market.
Q - What is the escalation process in the event of OTA SW update failure and the car cannot be
used?
A - Depending on market setup, assistance will be provided to the customer by either Call Center
and/or RSA.
The Call Center agent will be informed immediately via system integration of car and back-end
systems if any car is reporting a failed OTA SW update.
This may vary depending on market.
Q - Since all retailers have Workshop WiFi, how does OTA relate to Workshop WiFi?
A - All SW installations performed in the workshop today, will not be removed / overwritten due to
OTA.
The OTA will only handle general SW updates and QB.
Furthermore, OTA will NOT handle Pre-Delivery Service SW installations, SW installations
when replacing ECU or SW accessories.
Q - Customer hasn´t received any new SW to the car but the neighbor’s cars have - what’s the
reason?
A - Each car has a unique configuration.
Not all cars are updated at the same time with the same SW packages.
You will only receive an OTA SW update if it is applicable to your car.
Q - Is there information cascaded in conjunction with upcoming/pending OTA-release?
A - Currently, Volvo Cars central quality organization will inform the NSC when an OTA SW update
is about to be released in their market.
Q - How does the customer receive information about an upcoming / pending OTA SW download?
A - If the customer has automatic download turned on in the settings menu, the download will take
place seamless in the background.
If the customer has automatic download turned off, a prompt will occur every time the customer
enters the car, asking if SW can be downloaded to the car.
Once the installation prompt appears, the SW is then available for installation in the car.

Download = SW downloaded from cloud to car.
Installation = SW installed in the car.
Q - Can the customer schedule the OTA installation?
A - They can choose between 2 options: “now” or “later”.
If the customer chooses “later”, they will continue to be prompted to install the SW until they
choose “now”.
“Now” means that the car will start to install the SW when the prerequisites are met, i.e. car is
locked and both 12V and high voltage battery SOC are OK.
Q - Can the SW be installed without internet connection, e.g. in an underground garage of a hotel or
home parking?
A - In-car internet connection is only required to transfer the data-package to the car.
The installation procedure does not require internet connection.
NOTE! Without internet connection, the customer will not receive a notification message in
their Volvo Cars app that installation has finished.
Also, the car cannot automatically report back if a failure has occurred.
In the back-end system it will most likely report a timeout, triggering a case for a Care Center
agent to act upon.
Once the car re-establishes an internet connection, it will begin sending the information.
Technically, the car needs connection once it’s “woken up”, sending a signal to cloud saying the
new installation was successful.
Q - Where can the technician find information about how OTA updates work?
A - Using VIDA: Design and Function documents.
Information is also available in TRIP.
Q - How do I know if there is a problem with the external MNO (Mobile Network Operator)
connection of the car?
A - If MNO has a problem, - “No internet Connection” - all the other connected services will not
work, usually visible on the upper corner of the screen, as in an Android telephone.
Q - Can the customer install their own SIM card in the car for data-traffic?
A - No, it’s only possible to utilize Volvos built-in SIM card
Q - What happens to the OTA SW package if the workshop installs the SW using VIDA?
A - The current OTA SW will be removed, and VIDA will show status “Cancelled”.
The customer will no longer be prompted with the installation question in the car display.
*NOTE! If SW is installed using VIDA, the OTA-update will automatically be removed. The OTA
update will also be removed and not be redeployed if a new VIDA readout is performed.
Q - Can the workshop technician know if the customer car has an ongoing OTA SW package
downloaded but not yet installed?
A - By doing a VIN-search using VIDA; the technician can find this information.
Using VIDA: Tab “Software History” - “Order History”, Order Reference: OTA and Order Status:
Delivered.
NOTE! The customers car needs to have connectivity with the cloud.

Q - What should technicians use as a claim-code when fixing a car with related OTA-problems?
A - Normal warranty policy and procedures apply.
Q - If a customer calls with an issue, where do I as a technician find the information about the OTA
SW package?
A - Using VIDA: Tab “Software History” - “Order History”, Order Reference: OTA and Order Status:
Failed or Cancelled.
NOTE! Status Failed in VIDA could mean one of two things - “Critical Failure” or “Failure”.
“Critical Failure” = Message in the car “The update could not complete – please pay extra/
careful attention to error messages”.
Car must be taken to a workshop to be repaired.
Q - How can the technician take care of a car with an OTA “Critical Failure”?
A - Follow the normal fault tracing for interrupted SW download and if support is needed, please
contact your local helpdesk through your normal escalation process.
Q - Can the customer connect the car to local WiFi to handle the SW download?
A - No, the car does not have this functionality.
The transfer of data is performed over the car’s internal SIM card and is carried out when the car
is in “Active mode” i.e. during driving.
Q - Are there any battery minimum State Of Charge (SOC) conditions required prior to SW
installation?
A - Yes, the car will automatically check the SOC in the 12V battery immediately before an attempt
to install the SW.
The car will also check if the SOC-level in the propulsion High Voltage battery is above 40% or
higher before an attempt to install the SW.
Q - Will there be any kind of disclaimer in the event that a SW download could overwrite some
“non-Volvo SW” such as non-homologated SW from 3rd party company?
A - No, there will however be a control function in the back-end system highlighting if individual
configuration applies to the cars in the OTA deployment.
Volvo Cars SW Release Team will then decide if SW shall or shall not be deployed to those cars.
Unless the SW part-number is the same as a Volvo part number, if there is no conflicting data,
then the SW will be installed.
If any non-Volvo / non-proprietary SW from a 3rd party company is detected, this will be
overwritten.

SW INSTALLATION FAILURE HANDLING
Q - Customer notice message in the car - “The installation could not start - Your installation was
interrupted due to failed conditions. Make sure that the car is locked, and the battery level is
above 40% at time of installation. Please try again”.
What can the customer do?
A - Please check that the High Voltage propulsion battery level has a minimum 40% SOC, and that
all windows are in the upper closed position, as well as the doors/boot/hood are closed.
Also check if the car was in use or opened with the mechanical key when the scheduled
installation was due to take place.

Q - How will the customer be contacted in the event that the car has experienced a “critical failure”
and the OTA system has informed the Customer Care or RSA organization?
A - The customer will receive either an SMS push notification or a personal phone call.
NOTE: (Market dependent).
Q - What does “Critical Failure” mean?
A - “Critical Failure” means SW is missing in one or more of the ECUs and needs to be updated
physically at a workshop using the VIDA workshop tool and a physical connection to the car.
This cannot be resolved by OTA SW update.
*Q - After a successful OTA installation, are the DTCs cleared as they are when installing SW with
VIDA?
*A - No, the stored DTCs are not actively cleared during OTA installation, but depending on how
the SW is implemented, it may be that the SW is overwriting the memory where the DTC’s are
stored, it may vary from node to node.

Warranty claim info:
Normal warranty policy & procedures apply.

VEHICLE REPORT:
Please see TJ 35898 for how to recover a failed OTA in the workshop with VIDA and determine if
additional support is needed.
