August 2021 TechTIPS Page 1 of 10 Subaru Service and Technical Support Line Newsletter ©2021 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: Nicholas Lehman from Capital Subaru of Greensboro in Greensboro, NC June’s winning QMR of the Month submission detailed the diagnosis and repair of 2020MY Outback Limited with customer concerns of the Reverse Automatic Braking, Blind Spot Monitoring, and Power Steering warning lights coming on intermittently. After road testing and verifying the warning light concerns would duplicate when driving over bumps and rough roads, Nicholas suspected a loose harness connection. He proceeded to perform a DTC scan revealing various loss of communication codes in the advanced safety CAN system. After review of the related wiring diagrams, the search was on for the suspected poor connection. While wiggle testing various sections of the instrument panel (IP) harness, Nicholas duplicated the concern approximately 8 inches below connector i52. Here, he found the IP harness had not been secured properly to a body clip and was rubbing against a steering column alignment pin. He proceeded to carefully dissect the harness in the affected area where two CAN system heat-shrink wrapped joint connectors are located, each containing 4 wires. Closer inspection revealed one of the 4 brown CAN wires was not secured to the other 3 within the shrink wrap causing the poor connection. Nicholas went further by inspecting both CAN joint connections, soldered and re-wrapped them then went on another “bumpy” road test to confirm the repair before reassembling the IP. His QMR detailed the diagnostic steps taken, test results and included multiple quality photos documenting the repair. In appreciation for going the extra mile and sharing his experience with us, Nicholas will be receiving the following from his Field Service Engineer: $500.00 Snap-On gift card SUBARU TECHLINE HOLIDAYS & HOURS OF OPERATION Labor Day: (Closed) Monday, September 6, 2021 Mon. – Thurs. 8:30AM – 7:30PM EST Friday 10:30AM – 5:00PM EST Saturday 9:00AM – 3:00PM EST The Subaru TechTIPS newsletter is intended for use by professional Technicians ONLY.

Congratulations and THANK YOU to our June 2021 QMR of the Month Award recipient! Continued on the next page August 2021 TechTIPS Page 3 of 10 02 New and Remanufactured Short Block Replacement Tips & Break-In Procedure 1. Packaging, serial numbers and documentation. When receiving a crated short block assembly, be sure to inspect for exterior damage to the box/crate/ plastic shipping container. Document and report any damage to your parts representative. After opening the box, it is good practice to immediately document the short block serial numbers. These numbers will be necessary to complete The Credit Request and Diagnosis Form. This form needs to be completed with EVERY short block replacement and can be found under the Forms and Downloads section on Subarunet. It is a good practice to attach a copy of the completed form with the Repair Order. If your retailer has an electronic DMS (Dealer Management System; ie, ADP or CDK), Techline recommends taking a picture of the serial number or tag, and saving it. If you are not familiar with identifying these number sets, please refer to document code SNLG_01; Serial Number Location Guide on STIS. Remanufactured Block serial number missing? When receiving a remanufactured short block assembly, it may be found that the old serial number is ground off. This is normal for remanufactured short block engines only. Please use the metal tag glued to the top center of the block for serial number identification. Note: On some models, the plate is covered by the coolant crossover pipe and will not be able to be read after installation. Continued on the next page August 2021 TechTIPS Page 4 of 10 New and Remanufactured Short Block Replacement Tips & Break-In Procedure (CONTINUED) 02 2. Short block inspection and preparation. When removing the engine from the crate, inspect the cylinder walls and machining. Make sure no damage to the mating surfaces is found (gouges, sever pitting, etc). If no lubrication is found on the cylinder walls, apply a thin coat of clean engine oil to the cylinder wall surface with an oil squirt can. DO NOT use a rag or fiber towel. If a large puddle of oil is found at the bottom of the crate, or in the plastic wrap, apply a light coating of clean engine oil across the crankshaft journals (engine upside down). This should be done before any other components are installed onto the short block. After application, rotate the crankshaft clockwise one full rotation (still upside down) to have gravity help move the oil down onto the bearings. The crankshaft keyway should be returned to its original starting point (continuing in a clockwise rotation) to coincide with engine timing chain installation. Do not rotate the crank shaft counterclockwise other than when instructed in the timing chain installation instructions. Be sure to review 02-157-14R, starting on page 7, for valuable information about cleaning, inspection and assembly of chain driven engine components. 3. Engine Break-in recommendations There are several myths surrounding proper break in procedures for a new/freshly rebuilt engine. However, the Subaru recommended break-in procedure for naturally aspirated and turbocharged engines, can be found in the Owner’s Manual. These recommendations cover all situations and circumstances. Before installing the long block assembly into the vehicle, rotate the engine clockwise several full rotations BY HAND, with the engine filled to the proper level. The crankshaft counterweight will be soaked in oil and help lubricate the internal surfaces throughout. This will also supply oil to the main pump and saturate it. If any binding is felt or the engine will not rotate, STOP, do not force the rotation. This could lead to broken components. Instead, inspect for craftsmanship errors. Note: Turbo engine head gaskets have different specifications compared to the N/A engine head gaskets. Under NO circumstance should the starter be used to prime the engine with engine oil pressure. NEVER use clear flood mode to prime the engine with oil pressure. It is best to have the engine ready to start, on a cold start, and let it run. (The above picture is taken directly from the owner’s manual) Continued on the next page August 2021 TechTIPS Page 5 of 10 07 Door Lock Battery Back Up Unit Techline has received calls about identifying a newly implemented device for the door lock system. The Battery Back Up power source was implemented into vehicles outlined in the chart below. The Battery Back Up unit provides power to the door locks in the event of a collision that disables the standard 12v power source. When the vehicle receives a strong impact, all the doors and the rear gate are automatically unlocked, so as not to trap the vehicle occupants. The device is mounted above or near the audio unit in most cases. Refer to STIS for specific model removal/installation, and inspection. Note: When the ignition is turned on, the capacitor in the device is charged for 90 seconds.

If the filler neck, EVAP vent line and EVAP filter are free and clear, look at the internal flapper valve of the fuel tank. This can be done easily with a borescope. Start by removing the inlet hose off the tank and perform the inspection. Confirm your findings by removing the fuel pump and inspecting the flapper valve from the inside of the tank. The photos below are an example of a deformed flapper valve. Deformed valve Continued on the next page August 2021 TechTIPS Page 7 of 10 Gen 3, 3.1 and 3.1 alpha Harman and Gen 4 Denso CP1 – Check for conflicting accessories prior to performing a software update via USB Port 15 Prior to performing a software update via USB thumb drive, please check the USB Port for the presence of conflicting accessories (ex: additional thumb drives, chargers, etc.). Please remove all accessories connected to USB Port prior to performing update. Leaving conflicting accessories connected while performing an update may result in black display or the update failing. Example: Gen 3 Bluetooth streaming stuttering issue update AKA BT Skipping with Apple watch paired 15 Techline has received reports from the field regarding stuttering/skipping concern while a customer is streaming music via Bluetooth connection with phone device. It was found the concern was consistent when the customer had their Apple Watch paired via Bluetooth to their phone device, and their Phone Device Paired via Bluetooth to the Head unit. The following steps have been provided for a work around of the concern. NOTE: This is not an problem with the head unit and should not lead to unit replacement. This is a iPhone related characteristic. SOA is actively working towards a resolution. 1. Confirm Wi-Fi status of the Head Unit (ON/OFF) a.
