December 2020 TechTIPS Page 1 of 8 Subaru Service and Technical Support Line Newsletter ©2020 Subaru of America, Inc. All rights reserved. 01 QMR of the Month We are pleased to announce this month’s QMR of the Month Winner: David Jodat from from Subaru City of Milwaukee in Milwaukee, WI The winning Quality Monitoring Report selected from October’s submissions involves diagnosis and repair on a 2020 Legacy with an unusual concern of the trunk opening when either pressing any of the door lock / unlock buttons or shifting the CVT into reverse. The customer also reported receiving STARLINK notifications of the trunk being open after a Remote Engine Start request was made. After confirming the conditions as reported, David started his diagnosis by reviewing the wiring diagram and determining lock / unlock signals are sent by the BIU through a common wiring harness connector (i4). Wiring checks and scoping the related signal outputs identified an abnormally high amount of voltage on the trunk release circuit when operating the door locks or shifting into reverse. This led David to suspect an issue with the wiring for the unlock output and the trunk unlock circuits. After closely inspecting the related wiring, pins and harness connectors, all were found to be fine with no visible problems. He then removed the trunk unlock signal wire from connector i4 and rechecked voltages. The high voltage identified earlier was gone and the door locks operated normally. This test confirmed the vehicle-side wiring was fine which led David to be suspect of the BIU being internally shorted. His suspicion was confirmed as after replacing the BIU, normal door lock (and trunk release) operation was restored. David’s winning QMR included highly detailed descriptions of his testing and results along with excellent photos and multiple short videos to document this unusual condition and related repair. In appreciation for going the extra mile and sharing his experience with us, David will be receiving the following from his Field Service Engineer: $500.00 Snap-On gift card SUBARU TECHLINE HOLIDAYS & HOURS OF OPERATION Holiday Break: (Closed) Thursday, December 24, 2020 Friday, December 25, 2020 Saturday, December 26, 2020 Thursday, December 31, 2020 8:30am-4:00pm New Year’s Holiday Break (Closed) Friday, January 1, 2021 Saturday, January 2, 2021 Mon. – Thurs. 8:30AM – 7:30PM EST Friday 10:30AM – 5:00PM EST Saturday 9:00AM – 3:00PM EST Articles Contained in this Issue Click on a title below to jump to the article.

Congratulations and THANK YOU to our October 2020 QMR of the Month Award recipient! December 2020 TechTIPS Page 3 of 8 This series features TechTIPS articles frequently referred to by Techline. This month’s feature is from December 2016. 11 DTC P0171 Diagnostics Unmetered Air • Air entering the engine after the MAF will cause lean air/fuel mixtures. o Inspect all air intake connections for damage or looseness after the MAF. o In order to locate air leaks which cannot be visually inspected, use a method of fuel enrichment while monitoring your fuel trims. If the fuel trims drop toward 0% or A/F sensor returns to ≤1.0 during enrichment of a certain location, suspect an air leak. o Test the CPC solenoid and brake booster by blocking the hose connected to the component while monitoring the fuel trims to determine if there is a fault. Exhaust • Air entering the exhaust system between the cylinder head and A/F sensor will also cause a false lean condition. Metering devices • Metering devices for the air/fuel mixture can send incorrect information to the ECM causing incorrect fuel corrections. o Inspect the connections at all air/fuel metering devices for poor connection and contamination. o Swap the MAF and A/F sensor into a like vehicle to see if the condition follows the sensor. Combustion chamber • Poor combustion in a cylinder can result in unburned oxygen. The A/F sensor will read the unburned oxygen as a lean condition. o Verify valve clearances and compression readings are within specifications according to the applicable Service Manual. o Information regarding cylinder leak-down testing can be found on STIS in Technician’s Reference Booklet: Engine Theory and Diagnosis MSA5P2106C. December 2020 TechTIPS Page 4 of 8 11 EVAP System Smoke testing In the past several months there has been an increase in reports relating to Technicians finding, a “leaking” Evaporative Leak Check Module (ELCM). In these reports, technicians are completing EVAP system smoke testing with the ELCM electrical connector disconnected discovering that some leakage occurs. This condition is normal and does not indicate a failure of the ELCM. The drain side of the ELCM is normally only exposed to atmospheric pressures. Any pressure greater than atmospheric pressure can induce leakage from this connector. For more on EVAP system diagnosis, pressure and smoke testing refer to the Intermediate Fuel Injection Systems TRB document MSA5P24211C. 15 STARLINK Update- Retirement of the 3G Cellular Network Providers of wireless data networks will be phasing out their 3G cellular networks beginning in February of 2022 to make room for newer technologies. As a result, devices requiring 3G networks such as the hardware in 2016-18MY Subaru models with an active STARLINK Safety & Security package will no longer operate unless they are updated. This means features like Automatic Collision Notification (ACN), SOS Emergency Assistance, Stolen Vehicle Recovery and remote features will be cancelled after the transition date. A specific day / date has yet to be determined. Owners of affected vehicles with active subscriptions will be notified via e-mail on March 10, 2021 encouraging them to schedule a service appointment to have the applicable upgrade performed if they wish to continue utilizing their STARLINK services. Additional information regarding this change is forthcoming. In the meantime, FAQs about the 3G Network Retirement can be accessed on Subarunet: Parts/Service-Prgms/ Accessories > STARLINK/MySubaru-Fixed Ops. 15 Wireless Phone Charging Accessory Techline has received requests for more information and operation characteristics of the new Wireless Charger Accessory. Many of the inquires are regarding operation temperatures and customer concerns of their device being warm to the touch. The wireless charger and the mobile device will become warm during charging, this is normal and is not the sign of a malfunction. For more on the Wireless charger Accessory and Operation Manual search STIS > Accessory Installation Guides > Document code: H671SAN200. STANDARD OPERATION: 1) Place the vehicle in ACC or ON mode. The LED indicator will illuminate white indicating the wireless charger is in standby mode and ready to charge. 2) Place the Qi (pronounced “chee”) enabled mobile device into the charging pocket with the screen facing up. The LED indicator will illuminate blue and mobile device charging will begin.
