01 2019MY FORESTER QUALITY MONITORING TEAM NEW MODEL LAUNCH
A Special SBR Quality Monitoring Team is currently in the USA monitoring the launch of this much-anticipated new model. The Team is very interested in EVERYTHING related to this new vehicle. They are looking for specific and detailed information on EVERY condition identified. Naturally, this includes any repairs performed. It also includes cases when a customer comments on a function or condition considered to be a normal operational characteristic. This includes any improvement opportunities where some feature or function could be made even better. We are asking you to be our eyes and ears with this new model.
For high priority, unusual, or serious concerns, we ask that you call SOA's Techline and open a new case. When calling, be sure to have Freeze Frame Data (saved electronically, not a printout) or SSM data streams where applicable. It is crucial to also include troubleshooting tree results from the Service Manual found during diagnosis.
QMRs are the best and preferred reporting method for communicating any new model feedback. When submitting a QMR, please remember to include any Freeze Frame Data (electronically, not a printout) or SSM data streams where applicable. It is crucial to also include troubleshooting tree results from the Service Manual found during diagnosis. Photos and videos, where practical, of the condition prior to repair are also extremely helpful for the team to fully understand the condition.
Provide as much detail as possible on the customer complaint, the actual condition found, and all findings. Your detailed feedback is strongly requested and greatly appreciated. These items are crucial so the team can accurately understand the condition and how to address it.
While there is no guarantee a change will occur based upon any individual report, we can guarantee nothing will happen if we don't know about it. Our request is to report EVERYTHING, even if it seems to be just a small or straightforward repair.
QMRs, Techline Cases, CRS Cases and Warranty Claims are being reviewed daily. Team Members may contact Retailer personnel for additional details, photos, videos, part collections, or to arrange an on-site inspection. We ask for your cooperation in quickly responding to these requests for additional information. Please save all removed parts no matter how small, including gaskets, clips, fasteners, any filtered sediments, or other small bits and pieces. The rule of thumb is, if you report it or claim it, save it (including any drained fluids).
Please note, questions may come to you regardless if an QMR is submitted or not so, please keep detailed notes on all repairs.
As a reminder, QMRs must never be used to request escalation of a repair, request information, or for any other purpose than to notify SOA of a new or trending condition. Authorization or Repair Escalation Requests must always go through normal channels for the fastest, most efficient handling. Paint or Glass Authorization requests must go through the Techline Authorization System on Subarunet. All other authorizations must be reviewed in advance with your DPSM.
We THANK YOU all in advance for your great support and assistance in making this launch successful.
2019MY FORESTER: AUTO START-STOP AND DRIVER MONITOR SYSTEM DIAGNOSTIC 01 INFORMATION
The new 2019MY Forester is equipped with the Auto Start-Stop system which under the right conditions, shuts the engine off when the vehicle is stopped then restarts it when pulling away from the stop. Another new feature is the Driver Monitor System (DMS) which actually monitors the driver's eyes for signs of fatigue and when determined necessary, activates audible and visual warnings to help keep the driver alert.
The TCM supports the Data Monitor function for the Auto Start-Stop system. Currently, the Service Manual text for the related prohibition Reference values are listed as "Permit" or "Not Permit" but the SSM displays them as "ON" or "OFF". Until corrections are made, "ON" means "Permit" and "OFF" means "Not Permit". See the reference images below:
SSM Screenshot Service Manual The DMS system is supported by the Data Communication Module (DCM). The error involves incorrect cancel code time stamp data. The repair will be to reprogram the DCM with a file included in a future SSM update release.
07 ASCENT AUTOMATIC WIPER RAIN SENSOR INITIALIZATION
Whenever the Rain Sensor is removed or replaced, initialization of the sensor must be performed. Currently, for 2019MY Ascent, the Automatic Light and Wiper (ALW) control module does not display as an available system on SSM4 (ver. July 2018). Setting the SSM4 software as a 17MY Legacy/Outback will allow access to the Ascent ALW CM and calibration can be performed. As a workaround until SSM4 is updated, please follow the steps below:
- Open SSM4 and select Diagnosis
- Enter the Vehicle Information as 17MY Legacy/Outback
- Connect DST-I to the ODB connector
- From Each System select Automatic Light and Wiper
- From Work Support select Sensor initial setting
If you encounter any trouble with the procedure above, please contact Techline for assistance.
11 2019MY ASCENT: DTC P0606, CONTROL MODULE PROCESSOR: DIAGNOSTIC HINTS
The Techline has received a small number of reports regarding DTC P0606 where following the Service Manual diagnostic steps has not isolated the root cause of the DTC. To properly diagnose this DTC, it is important to understand the cause is a discrepancy between the actual engine torque value and the engine torque value as calculated by the ECM. Related field reports also outline where P0606 was stored and the root cause was determined to be loose or missing hardware for the intercooler piping which resulted in a boost pressure leak. In a case where the actual engine torque is reduced, as it would be when a boost leak is present, a stored DTC P0606 may result. While the Service Manual currently directs the Technician to perform various electrical tests first, the diagnostics will be revised to include instruction to inspect for any boost pressure leak between the turbocharger and the throttle body.
To summarize, if a vehicle presents with a stored DTC P0606, always be sure to start by inspecting and confirming all turbocharger pressure side and intercooler piping hardware is in place, properly secured and fully tightened before proceeding further with any electrical testing.
15 FUJITSU/DENSO 10 IPHONE CONTACT PICTURE DISPLAY-UPDATE
In the June 2018 TechTIPS, we provided the contact photo specifications for Gen 2 & 2.1 D10 (formerly F10) head units. The Techline continues to receive calls about picture contact concerns. According to investigation by D10, this is a compatibility issue due to a specification change of iPhone. The image data format was changed starting from OS 11.3 and the new format is no longer compatible with Gen 2 & 2.1 head units for images larger than 800 bytes. D10 has implemented an enhancement to be available in the next software update. This is tentatively planned for released in December 2018. Installation of an exchange or new head unit will not correct this condition currently.
15 SIRIUS XM LIST AND VOICE TUNING CONCERNS ON GEN. 2 & 2.1 DENSO (D10) AUDIO UNITS
When using the list function to display available channels, only two channels (Ch000 and Ch001) are displayed. After an SXM programming update in August 2018, it was found that the D10 Gen 2 and 2.1 head units were not capable of handling the new line-up due to a software limitation of the head units. Please note the number of received channels varies upon the SXM subscription package. The actual number of receivable channels may also change depending on the current SXM channel line-up. At this moment, only customers with the full subscription package are affected by the condition as that lineup contains more than 256 channels. Impacted customers may still use either the direct tune functionality, the radio tune knob, or save their favorites to their presets. D10 has implemented an enhancement to be available in the next software update. This is tentatively planned for released in December 2018.
Installation of an exchange or new head unit will not correct this condition currently.
2019MY IMPREZA/CROSSTREK REMOTE ENGINE START (KEY START) - CONTROL MODULE INSTALLATION 15
Vehicles & Remote Engine Start Kits (RES) Affected:
- 2019MY Impreza/Crosstrek with Key Start Ignition - H001SFL400
- 2019MY Impreza/Crosstrek with Key Start Ignition - (Permanent Fix - Coming soon)
Current Condition: If proper care is not used when mounting the RES Control Module, the RES connector/harness could come in contact with a factory metal bracket following reassembly. SOA recommends a quick visual inspection of this area once the glove box inner cover is replaced. See below, Figure CC.
Also note:
Long Term Solution: Refer to the updated H001SFL400 Installation Instructions, Issue 01 (Dated: July 25, 2018) to ensure the revised ECU mounting procedures are followed. The installation instructions illustrate how to mount the ECU 1/2" lower to avoid any contact with the factory metal bracket after reassembly. See below, Figure P.
SERVICE MANUAL CORRECTION: REAR TRANSMISSION CROSSMEMBER/TRANSMISSION MOUNT REMOVAL-IMPREZA AND CROSSTREK CVT MODELS 16
When removing the rear transmission crossmember to replace the cushion mounts on a 2017-18MY Impreza or 2018MY Crosstrek, removal of the rear exhaust pipe (pipe between the spring bolt connection and front muffler) is required, NOT the front pipe as currently directed by the Service Manual. The applicable Service Manuals will be updated with this change soon.
IMPORTANT REMINDERS:
- Whenever removing the rear crossmember, always support the transmission with a transmission jack.
- NEVER support the transmission by the oil pan.
- Always use new gaskets and the specified one-time use nuts whenever re-installing exhaust components.
- Torque all hardware to proper specification.
