SERVICE INFORMATION BULLETIN
APPLICABILITY:

2023MY Solterra

SUBJECT:

Solterra Connect

NUMBER: 15-310-23R
DATE:

05/23/23

REVISED:

08/31/23

INTRODUCTION:
This Service Information Bulletin announces the best practices when troubleshooting Solterra
connect concerns if the customer’s driver profile is not the primary driver profile and/or inability to
activate Solterra Connect.
Solterra operation, diagnosis, and repairs differ significantly from previous Subaru models.
Technicians are required to complete Solterra training prior to performing any Solterra service
procedures. Solterra Service Manual, Owner’s Manual, Quick Start Guide, TechTIPs, and TSBs
MUST be reviewed before attempting to rectify Solterra customer concerns. Refrain from using
procedures and best practices designated for Subaru models other than Solterra on Solterra.
This document will outline a graduated escalation path of steps designed to reach a successful
Solterra Connect enrollment with the customer profile as the primary driver profile. Being
unprepared, not closely adhering to the procedure outlined here, or taking creative liberty with the
steps will result in failed results and extended downtime of the customer’s vehicle.
Before starting, the Technician must have the Solterra Connect Application (App) loaded on their
phone and registration completed. This registration does not incur any cost or obligation to any
subscription but will allow the Technician to add themselves as a driver to any Solterra. Please refer
to Appendix B on how to set up a Solterra Connect profile.
SERVICE PROCEDURE INFORMATION:
PREREQUISITES: Phones attempting to connect to Solterra MUST meet the following
prerequisites.
1. Bluetooth setting is turned on.
2. Wi-Fi is enabled.
3. GPS location data setting is turned on.
4. Acceptance of Solterra Connects request to use background data.
5. Once connected to the vehicle, the Service Communication Consent MUST be accepted.
6. Once connected to the vehicle, the Master Data Consent MUST be accepted.
CAUTION: VEHICLE SERVICING PERFORMED BY UNTRAINED PERSONS COULD
RESULT IN SERIOUS INJURY TO THOSE PERSONS OR TO OTHERS.
Subaru Service Bulletins are intended for use by professional technicians ONLY. They
are written to inform those technicians of conditions that may occur in some vehicles,
or to provide information that could assist in the proper servicing of the vehicle. Properly
trained technicians have the equipment, tools, safety instructions, and know-how to
do the job correctly and safely. If a condition is described, DO NOT assume that this
Service Bulletin applies to your vehicle, or that your vehicle will have that condition.

Subaru of America, Inc. is
ISO 14001 Compliant
ISO 14001 is the international standard for
excellence in Environmental Management
Systems. Please recycle or dispose of
automotive products in a manner that is friendly
to our environment and in accordance with all
local, state and federal laws and regulations.

NOTES:
•

Declining the Solterra Connect requests for data access will not stop the installation of the
Solterra Connect App. It will not produce a warning message indicating that non-consent will
result in non-operation of the Solterra Connect App. When using the Solterra Connect App,
users must agree to all requests for data and location access, or the Solterra Connect App and
driver profile settings will NOT function as expected.

•

The Solterra is always connected to the Telematics Call Center, and no subscription is required
to connect to an operator by pushing the Solterra Connect button. Unlike other Subaru’s,
Solterra Connect is an opt-out telematics system that is always on. Enrollment is required for
the on-demand use of enhanced telematics services. Test calls can be performed by pressing
the Solterra Connect Button, identify themselves a Subaru Technician making a test call, then
requesting VIN and location.

•

When using Solterra Connect, ALWAYS use the most recent version of Android Play Store or
the Apple App Store available if your device does not accept automatic updates.

•

Technicians and/or customers having a previously created Toyota or Lexus App may receive
notifications stating an active account already exists. If this is encountered, use the same
credentials for Solterra Connect.

•

There are multiple ways to create a Solterra Connect account. There are Social Media shared
authentication options as well as creating a local account. Part of this process requires a
valid email and phone number. This information MUST BE VALID because connection will
require authentication Personal Identification Numbers (PINs) to be sent to the entered contact
information.

•

If any components such as the head unit of the DCM has been replaced, the procedure below
must be completed before proceeding with the rest of the steps in this TSB.

PRECAUTIONS:
1. Verify state of charge for the 12v auxiliary battery located under the hood.
a. Test and charge the battery if required using the DCA-8000.
IMPORTANT: When a vehicle has the power switch in the “ON” position for an extended period,
excessive 12v battery drain can be resulted.
2. Set the Auto Power Off function to “OFF.”
a. When a vehicle has the power switch in the “ACC” position for more than 20 minutes (the
EV system is not operating) or “ON” for more than an hour with the shift position in P, the
power switch will automatically turn off. However, this function cannot entirely prevent
12v auxiliary battery discharge. Do not leave the vehicle with the power switch in “ACC”
or “ON” for long periods of time when the EV system is not operated.
OUTLINE OF STEPS:
1. Perform a Heath Check using GTS and save it as it will be necessary to send to Techline
should you be unable to complete any of the steps outlined in this bulletin. If DTCs are
present, do not continue with this document until the Solterra is DTC-free.
2. Verify that the Solterra Connect LED is illuminated Green beside the Solterra Connect button.
If the LED is not green, contact the Solterra Connect Call Center (866 384 3574) for operator
assistance as to why the Solterra Connect LED is not illuminated.
3. Perform a test call by pushing the Solterra Connect Button, connect to an operator, and request
the VIN and Location. If you do not connect to an operator, contact the Solterra Connect Call
Center at (866 384 3574) for operator assistance as to why calls cannot be completed from
inside the vehicle. If no resolution from the operator’s assistance can be achieved, do not
continue using this document and refer to the applicable Service Manual.
NOTE: Speaking with a Solterra Connect Call Center Agent may only sometimes result in a repair.
In some cases, it may be necessary to continue diagnosis using the Solterra Service Manual as
indicated in Step 3 or contact Techline.
When contacting Techline, please be prepared to provide the test results of the procedures outlined
in this document and the Solterra Service Manual on STIS. Be ready to send Techline head unit logs,
GTS data for the head unit, and telematics, including an all-system scan and a video of the concern
you are attempting to repair.
4. Ensure the phone has the Solterra Connect App loaded and the profile registered.
5. Perform HU reboot. Verify the customer is the primary driver profile, then follow Appendix
A: Solterra Connect Enrollment Overview.
6. Perform a 10-minute 12V under-the-hood battery disconnect. After at least 10 minutes have
elapsed, reconnect the 12V battery, and verify the customer is the primary driver profile, then
follow Appendix A: Solterra Connect Enrollment Overview.

operation. All diagnoses and repairs of the Solterra Telematics and Infotainment Systems are highly
dependent on technicians following the Solterra service manual, Solterra owner’s manual, quick Start
guide, TSBs, and TechTIPs due to the need for more visibility of operational data. Technicians must
be prepared to provide test results and videos when contacting Techline.
DIAGNOSTIC STEPS:
Please ensure that you have reviewed all the information on pages 1 through 3 before
continuing. Failure to understand operational requirements will result in failed customer
concern resolution.
