SEOCONTENT-START
Subaru Service and Technical Support Line Newsletter 01 QMR of the Month We are pleased to announce this month’s QMR of the Month Winner: Christopher Vanaman from Rafferty Subaru in Newtown Square, PA Our March winner’s QMR outlined the diagnosis and repair of a 2020MY Outback which presented with the power windows and automatic seats inoperative. After confirming the conditions as reported, the SSM was connected and a DTC U1822 was found stored in memory. A check of the power supply circuits was next where SBF 2 was found to be blown in the under hood Main fuse box (M/B). Replacing the fuse restored operation of all systems but, Christopher set out to determine the root cause of the blown SBF 2. He began by inspecting the current (amperage) draw on each of the circuits powered by SBF 2. After ruling out the power window system, he continued monitoring the draw while operating the numerous functions of the power driver’s seat. While observing the meter and lowering the seat, the current draw was fluctuating to near 30 A then spiked to blow SBF2 again. Christopher removed the driver’s seat assembly and began a thorough inspection of the lift motor wiring. His inspection revealed a short on the purple wire where the seat switch harness passes through an opening in the seat frame. The insulation had rubbed through in one spot. The exposed, bare wire was shorting directly to the frame but only when operating the lift motor up or down. Christopher proceeded to repair the affected wiring and add additional cable ties as needed to better secure the harness and prevent any recurrence. He then replaced SBF 2 a second time. After reinstalling the driver’s seat assembly and clearing the memory, normal operation of all affected systems confirmed a sound repair. Christopher’s highly detailed report included all his testing results, connector and pin locations and a collection of exceptionally clear photos to further document the damaged wiring before and after repair. In appreciation for going the extra mile and sharing his experience with us, Christopher will be receiving the following from his Field Service Engineer. $500.00 Snap-On gift card ©2020 Subaru of America, Inc.

This series features TechTIPS articles frequently referred to by Techline. This month’s feature is from September 2017. 01 Lost Keys? Contact the Subaru Techline If you receive a vehicle from the customer where all their originally registered keys have been lost, contact the Subaru Techline for the necessary steps to program new keys. Depending on the immobilizer type, you will be unable to just program one new key without an original key. Both immobilizer Type-B and Type-D require an original key to make any changes to the immobilizer system. Without an original key, a new one cannot be added. Unsure of which type immobilizer you have? Refer to the Quick Reference Chart found in the October 2016 TechTIPS newsletter. Once you have confirmed the vehicle is the Type-B or Type-D immobilizer system, the following: • Verify the vehicle is onsite. • Open a Repair Order with all necessary information. ᵒ VIN, RO number, RO date, Mileage if it can be obtained, etc. • Verify key type (push-button, turn-key) • Contact the Subaru Techline. SOA will no longer clear immobilizer modules for salvage/rebuilt title vehicles. Please refer to the Service Manual/Registration Manual for Immobilizer for repair of these vehicles. When calling the Subaru Techline, please ensure all necessary information is available at the time of the call. Once connected with the Techline, we will be able to provide the necessary procedure to program new keys to the vehicle. Continued on the next page May 2020 TechTIPS Page 2 of 10 01 Lost Keys?

There are a few key conditions to keep in mind when testing for Parasitic Draw on STARLINK Telematics -equipped vehicles: 1. The Audio Unit (A/U) will keep a DCM awake any time the A/U screen is on or sound is playing, even when the ignition is switched off. 2. A DCM connects to the STARLINK server at the time key is turned off. When there is a network connection issue, the DCM will continue to attempt to connect to the server, and/or if the MIL lamp is illuminated just before IGN-OFF and network connection is poor. The DCM won’t sleep for up to 15 minutes after IGN-OFF. 3. The DCM will wake up if a customer uses any remote service function through Starlink APP. Continued on the next page May 2020 TechTIPS Page 3 of 10 07 Parasitic Draw (Dark Current) Testing and Telematics DCM (Continued) Condition #1: It is obvious the DCM is not the root cause of parasitic draw as the A/U will visibly be on and/or audio will be playing. It requires at least 3 minutes following ignition off for the A/U to power down. Condition #2: This is the most likely scenario for a misdiagnosis of DCM as the root cause of the draw. Checking signal strength for the DCM using SSM4 in your testing area is important and if signal strength is weak, testing should be completed after at least 15 minutes or more of wait time following ignition OFF. Condition #3: It would be rare for a customer to be attempting remote services functions while the vehicle is at the retailer for service for parasitic draw testing. A vehicles DCM can power up or stay awake for various reasons including but not limited to: software updates, Service Appointment Scheduler (SAS) usage and Ignition Off Data transmissions. When activated, the Stolen Vehicle Recovery function will keep the DCM awake for a couple of days (this is a very rare case.) Contact the SOA Techline to ensure Stolen Vehicle Recovery has not been activated if the DCM is not going to sleep after 15 minutes. The Telematics system LED can stay on for up to 5 minutes after Key Off and it is essential to wait at least 15 minutes after ignition off (key removed or all access keys at least 2+ meters away from the car) before proceeding to attempt diagnosis of Parasitic Draw and to determine if the DCM is the root cause of the draw. When diagnosing parasitic draw, it is crucial to follow the latest STIS Service Manual information as additional wait time may be required. Based on the information above, the best practice to rule out any possibility of an unexpected power draw from the DCM is to wait a full 15 minutes for the DCM to go to sleep. Use a watch or smartphone to keep track of time. After 15 minutes have elapsed, measure the dark current draw. If the draw exceeds specifications, perform the following steps to ensure the DCM power supply is eliminated: 1. Pull the M/B fuse (under the hood) feeding the DCM. 2. If the draw is still present, next pull the fuse feeding the ignition supply to the DCM from the front fuse box. 3. If the draw is still present, pull the fuse feeding the accessory power circuit to the DCM from the front fuse box. 4. If the DVOM is still indicating a parasitic load higher than 70mA, the DCM should not be considered the root source of the draw until further isolation methods have been performed to identify additional parasitic loads. NOTE: While the DCM may only take 15 minutes to go to sleep, there may be other control modules in the vehicle which take longer, up to 55 minutes. See the related Service Manual for these details. May 2020 TechTIPS Page 4 of 10 08 Combination Meter Settings: Kilometers to Miles When presented with a customer concern of the odometer reading in Kilometers instead of Miles, it is always a good idea to consult the Owner’s Manual. If the manual is not found in the vehicle, it can be accessed through STIS. Below is an example of the information found in the Owner’s Manual to correct this concern. 15 Incorrect Operation of Audio Unit After Rockford Fosgate Upgrade Installation APPLICABILITY: All Vehicles with Denso CP1 Multimedia Navigation (AVN) & Display Audio (DA) systems SUBJECT: 2020 Outback/Legacy Rockford Fosgate Audio Upgrade Kit There have been reports received concerning incorrect operation of the 2020 Outback/Legacy audio system after the installation of the Rockford Fosgate Audio Upgrade. Always refer to the Retailer Installation Instructions found in Subaru Tech Info System (STIS) and closely follow the instructions without skipping steps. Please see the items below to further assist in preventing concerns following the installation of the upgrade kit. Continued on the next page May 2020 TechTIPS Page 5 of 10 Continued on the next page 15 Incorrect Operation of Audio Unit After Rockford Fosgate Upgrade Installation (Continued) 1. Remember to inspect the Audio Upgrade Kit parts to ensure no missing parts or part defects as well as confirm the correct part numbers. NOTE 1: The amplifier part number should be H630SAN002. It was designed specifically for 2020 Outback/Legacy. NOTE 2: The Base model requires Tweeter Kit H630SAN100 to be added prior to installation of the Rockford Fosgate Audio Upgrade Kit. Tweeter Kit H630SAN100 is comprised of OEM parts and is not supplied by Rockford Fosgate. The Tweeter Kit is designed to improve sound with a full 6-speaker system (2 dash tweeters, 2 front door speakers, 2 rear door speakers). 2. Use extreme caution when performing removal, re-installation and all checks of the infotainment unit. The volume and tune knobs can be easily damaged, if excessive force is used to press the knobs in during checks or during handling. 3. Remember to always disconnect the negative cable from the battery sensor prior to starting installation. Never disconnect it directly from the battery terminal. 4. Verify the audio harness jumper wires have been properly set to select the correct audio profile for the target vehicle’s trim level.

If verification testing results in an unexpected finding and installation has been confirmed as correct, please submit a QMR including specific details about the condition found and review of the installation including pictures of connectors, harnesses, CP1 system software version, amplifier part number, etc. If possible, provide a video of the concern as duplicated and any steps required to duplicate it. 15 A/C and Heat Conditions: Use of Recirculation / Recirc Button Regardless if you are believer in Global Warming or not, in recent years we all are clearly experiencing some extreme variations in both temperature and humidity in ways not seen in the recent past. As a result, customers may experience higher temperatures and humidity conditions during any season than just those experienced in the past. Unusual temperature and humidity conditions may necessitate changes for how customers operate their HVAC system in order to achieve peak and desired performance. One of the most overlooked but key performance points is the preferred use of the recirculation or “recirc” button to control the flow of outside air into the cabin. When applied in a manner inconsistent with ambient conditions, this can lead to a few customer complaints. Two common examples are listed below. • Buildup of condensation or ice on the inside of windows can result from trapped moisture while having recirculate ON (recirculating cabin air) in winter. Switching recirculate to OFF will allow outside, lower humidity air into the cabin and allow natural drying to occur. Use of the front defrost / defogger is the most effective way to accomplish this drying action and will automatically change the recirculation setting to OFF (allowing fresh air in) for most vehicles. (Note: some older, manual HVAC systems may still require the recirc button be changed to OFF- Check the related vehicle’s Owner’s Manual). • Reduced air conditioner performance may occur when recirc is set to OFF (allowing fresh air in). Having the recirc OFF (fresh air in) combined with high ambient temperature conditions (more than 100° F) reduced air flow through the condenser (such as during severe stop/go traffic conditions without adequate space between vehicles, vehicle parked with front close to a wall or other restricted air flow conditions), can increase refrigerant temperatures and system pressures and lead to a reduction of performance. In severe cases, the system may even temporarily shut down until internal refrigerant pressures return to within the normal operating range. This can even occur fully charged systems operating at capacity. In such conditions, it is best to have recirculate in the ON position (recirculating cabin air) to achieve the desired cooling effect. The above examples represent only two possible scenarios and combinations of many conditions customers may experience. If the HVAC system appears to be operating correctly, it may prove helpful to inquire about the ambient temperature and humidity conditions during which the customer was experiencing the most recent concern. It may only take something as simple as a small change to the customer’s recirculation settings to ensure their desired comfort level is achieved under similar conditions in the future.
