APPLICABILITY

Models with Harman and Denso CP1 Infotainment

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. 

INFOTAINMENT CONCERN DIAGNOSTIC AND REPORTING FLOW

G16995481
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.

Please see chart below to differentiate CP1 Black/Blank Display cases and decide on the repair action

G16995482

Various resources are available to help diagnose and repair the Infotainment system: TSBs, TechTIPS, Techline and DSQMs.

Subarunet->Service Operations & Technical -> Forms/Downloads or Subarunet->Service Operations & Technical -> STIS 

SPECIAL NOTE:  For the latest updates on Tips for current concerns, perform key word search in "TechTIPS Article Locator Index" (Document code: SUTTIPSLOC), or review all relevant infotainment related TechTips from the "Accessories" (#15) tab found on the table of contents. To locate the "TechTIPS Article Locator Index" from STIS "Subaru Tech Info System", select "Online Reference".

SERVICE INFORMATION

REMINDER:  Customer satisfaction and retention starts with performing quality repairs.

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
    1. 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.
    2. 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.
    Level of Details Description Details
    Not Acceptable No Sound/No Audio
    Acceptable No sound from SXM radio, but there is sound from AM/FM radio. Audio streaming is working as well.
  2. Date/Time:  Obtain from the customer the date and time of the last occurrence. The customer may not remember the time of occurrence clearly. In that case, please confirm with the customer whether it was morning or evening and the day of the week etc.
  3. Data Log:  Download Infotainment system Data Log and note the Date/Time of last occurrence - see Appendix

    REMAINING INFORMATION 

  4. Confirm whether the concern is duplicated at the time of repair
    1. Note the frequency of occurrence. Is it: Constant or continuous (easily duplicated), Intermittent (happens frequently at least daily but not all the time with a good chance of duplication), or Random (happens with no set occurrence. Could be weekly or monthly. Very hard to duplicate.)
  5. Obtain the current Software Version the concern has been duplicated with (Clear photo of the Software Information Screen showing the latest software version is REQUIRED).
    NOTE: DO NOT  use the coding from this bulletin to submit the claim, if the software update resolves the concern. In that case please use the labor time codes from the related software update bulletin to submit the claim.
  6. Obtain the Video of condition being duplicated (may be supplied by the Customer if an intermittent or randomly occurring condition.)
    1. Verify the date and time of concern duplication.
  7. Obtain the Phone Information (Make/Model/Operating System Version) as applicable
    1. Screen shot of phone software version screen is BEST.
  8. Obtain SSM Data with DTCs and Related Troubleshooting Results.
    1. Always perform diagnosis of current DTCs which may be related. Any electrical concern may be impacting the operation of the audio/navigation system and must be resolved to eliminate it as a possible source of the condition. Conditions like this can be repaired TODAY.
    2. Revise following portal request format
    3. Attach troubleshooting results for all Bxxxx and Uxxxx DTCs infotainment specific B/U codes.
