Subaru of America, Inc. is proud to announce that the next phase of TechShare™ is here!

TechShare™ is Subaru of America’s vision for a fully integrated service solution that will address

the needs of technicians to efficiently maintain and repair Subaru vehicles.

This phase creates a path forward for our retailers, and most importantly for Subaru technicians,

using TechShare™ to open a Techline case. See below for the list of available case types

and what is required.

• Infotainment

• Lost Keys

• CID/CVN Verification

• Transmission

• Telematics

Submitting a case through TechShare is the start of the conversation with Techline. If the vehicle concern

falls into one of these case types, please create a case through Techshare prior to calling. Techshare cases

are assigned in the order they were submitted. Due to the volume of requests for assistance, if seeking

immediate assistance, technicians are encouraged to call Techline after submitting the case through

TechShare.
Currently, technicians can log into TechShare™ to:

• Create a Techline case for Techline to review and provide guidance.

• Receive notifications when the case has been updated by Techline.

• Comment on the case in TechShare for Techline to view.

CID and CVN Verification

Introducing the New ECM CID/CVN Check Tool in TechShare!

Subaru of America’s Techline team is excited to introduce the new CID/CVN Check tool now in TechShare

VIN Sessions! This tool is available for turbocharged vehicles and BRZ and will allow technicians to

instantly confirm if the internal software of the Engine Control Module has been modified for both

customer concerns and Certified Pre-Owned vehicle inspections, eliminating the need for a Techline

case. Technical Training has developed a step-by-step instructional video on how to use this tool. [Insert

Link to Quick Hits video]

Retailers are requested to use this feature when trying to verify CID and CVN for CPO certification. By

starting a VIN Session and uploading a clear picture or a screenshot of the vehicle information screen, the

tool will provide one of three possible responses.

Pass: The engine control module has Subaru original CID and CVN

Fail: The engine CID or CVN is not Subaru original

No Match Found: Additional steps are required to verify the authenticity of the CID and CVN. Please

submit a Techline case from the prompt in the report. This is the only way to create a Techline case to

check the CID and CVN. When the tool reports a “Pass” or “Fail” result, anyone in the service department

will be able to view the results. A printable report is available for any checks performed at your retailer.

Checks performed at another retailer will not have a printable report available, but the results will be

viewable in TechShare.

When the tool reports “No Match Found” technicians will be able to create a CID/CVN case with Techline.

Techline will take the necessary steps to check the authenticity of the CID/CVN, and technicians will be

notified and asked to rerun the check.
Transmission

Assistance with diagnosing transmission concerns is available through Techshare. There are 2 different

worksheets available for use with transmission concerns, and the “Transmission Diagnostic Worksheet”

will be used in most cases as this will cover concerns for DTCs, drivability, and data review.

Please complete any applicable DTC diagnostic path, TSB, or TechTIP procedure prior to seeking

assistance from Techline..

A TechShare case should only be created after performing the customer interview and operating vehicle

to replicate customer concern. Cases should include supporting documentation including all diagnostics

performed.

For example:

If submitting data for technical assistance, please include…

•
Results of customer interview
•
Completed worksheet(s)
•

•
Exact measurements of all diagnostic work
•
SSM all DTC check
•
SSM Multi-system monitor using provided settings file (Please refer to the June 2025 Techtip and

For most vehicles equipped with a TR690 CVT, the CVT diagnostic tool can be used. Please refer to

TSB 16-154-25. The CVT diagnostic tool should be used prior to creating a Techshare case. A Techshare

case should be created if the recommended repair from the CVT diagnostic tool has not resolved the

customer’s concern.

Creating a Techline case is not required for transmission replacement.

See 4/22 TechTIPS “Calling the Techline Revisited”

Completing the correct worksheet and providing the most accurate information will aid in a faster

resolution. See Below for an example of the “Chain Slip Worksheet.”

Telematics

Telematics case submission will allow for 3 different types of cases.

1. 3G SIM Activation

Techline case should only be created after latest software version is installed and customer has

signed customer commitment to Subaru Starlink enrollment on page 7. Once this request is

received and processed it may take up to 24 hours to perform SIM activation. Vehicle should be

held at retailer until they receive confirmation from Techline, then capacitance discharge should be

performed following 15-317-24

2. General Telematics Diagnosis

All assistance regarding Telematics can be found using this case type.

Technicians must be sure to follow all applicable TSB, TechTIPS, or diagnostic path before

submitting Techline case.

In most cases a TechShare case should only be created after performing customer interview and

operating vehicle to replicate customer concern. Case should include supporting documentation

including all diagnostics performed.

3. Solterra Telematics

All assistance regarding Telematics on Solterra can be found using this case type. It is

recommended to use 15-310-23R to assist in “Solterra Connect” diagnosis along with a Techline

case.

Taking the time to check the vehicle over to answer the questions in the worksheets can provide

extremely useful information that can aid in a faster resolution. See below for a fitting example:
