CP1 Infotainment

NUMBER: 15-304-22R
DATE:

10/11/22

SUBJECT:

Procedure for Techline Infotainment Concern Data REVISED:
Collection and Sharing via TechShare

07/31/23

This bulletin supersedes TSB 15-192-22 “Infotainment Concern Data Collection Guidelines” and
explains the process of using the Infotainment Form for Infotainment cases submission.

INTRODUCTION:
This Service Information Bulletin has been developed to outline the steps for gathering basic but
essential information during diagnosis of Infotainment concerns. The information collected will be
used to escalate potential software or phone side concerns. In some cases, these escalations will lead
to future software releases improving the infotainment system performance.
Anytime a repair is made to the Infotainment system, it must start with a clear understanding of the
concern reported by the customer and the steps to duplicate it. As with any repair, the second step
after understanding the concern is to duplicate it and determine if it is an operating characteristic or
unexpected operation. If the condition reported is an expected operating characteristic, this should
always be demonstrated to the customer to confirm their understanding before releasing the vehicle.
Successful repair of a customer’s Infotainment concern can only be achieved by following a proven
diagnostic strategy as outlined below.
Concern description, Date and Time of duplication, Data log are essential elements for
understanding the customer concern and must be included with all submissions.

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.

•

Always confirm the condition as reported by the customer.

•

Always document the date and time of the last concern duplication and collect the data log.

•

Always attempt to use customer’s setup and equipment for concern duplication. If you can’t
use the customer’s phone make sure the phone you test with is as close a match as possible
by using a phone with the same make, operating system, and carrier version

•

Always document the concern by capturing the steps leading to duplication and when
possible, record a video of concern.

•

Make sure the concern is not due to the setup or the customer’s accessory/phone. As an
example does the condition occur with all phones, all phones of the same type or just the
customer’s phone that are connected in a similar way.

•

Always document Infotainment system software version and accessory details: make, model,
software version.

•

When you replace hardware or perform software update in attempt to repair a concern, please
claim appropriate labor operation. The warranty information in the bulletin is not applicable
in those instances.

It is IMPORTANT to understand some conditions cannot be resolved in the field solely by parts
replacement. Some of these situations will require a Techline assistance or assistance from the
DSQM. Those are the times, when getting essential data about the concern as well as the diagnostic
performed are the most critical.
NOTE: In case of CP1 Black Display concern confirm it is duplicated with the latest software
version. If yes, it would be due to the hardware failure in the CCU (Cockpit Control Unit) part of
CP1 system. CCU replacement is advised as the next step to repair this concern. Please follow proper
exchange procedure.
If you’d like to request assistance from Techline regarding an infotainment case, please have all
your files and documents and submit an infotainment case online through the TechShare website. If
the vehicle has been in with previous infotainment concerns, please have the previous repair order
information available. If you have any issues with the process or technical issues, please contact
Techline.
Please keep in mind the basic essential information has to be captured to enable assistance as well as
report a concern. Following the steps outlined below should be a good start.

STEPS TO GATHER BASIC INFORMATION
 ESSENTIAL INFORMATION
1. Obtain a detailed description of the customer concern including steps to duplicate it
A. Multiple concerns must be addressed one by one as each may have a unique cause. Consult
the customer, if you do not clearly understand each reported concern and document each one
separately. Lumping concerns together will delay or prevent review of the reported condition.
B. Describe the condition in detail. What is the customer description for what is happening.
How would you as a technician describe it. Include notes on the features that are not working
but also what is working even when the condition occurs. The table below shows an example
of the detail being requested.
