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: Jeremy DeGroot from Capitol Subaru in San Jose, CA Our June QMR of the Month report outlined the diagnosis and repair of a 2020MY Impreza which presented with a customer concern of all the combination meter warning light coming on. After confirming the condition as reported, Jeremy began his diagnosis by checking for DTCs which revealed a U1235 in each of the networked control units for a loss of communication with the EyeSight system. He proceeded to remove the EyeSight stereo camera cover and found connector R137 securely locked into the camera assembly. Jeremy then used his DVOM to inspect for proper ignition and battery power supply voltages along with the ground wiring to the camera and confirmed normal values for each. Since proper power and ground values were present and there was still a communication failure, Jeremy accessed the EyeSight wiring diagram and turned his attention to the CAN system. After disconnecting the battery to check resistance of the CAN network at pins 9 and 10 of the EyeSight camera connection (R137), he found open resistance (OL) when it should have been approximately 60 ohms. Further review of the wiring diagram showed only one harness connection between the stereo camera and the BIU: R96 to i19 located behind the rightside A-pillar trim. With the intention of using the split-half technique to isolate the apparent open CAN circuit, he removed the A-pillar trim to access the suspect harness connector but immediately noticed pin 5 of R96 (blue CAN wire) had backed out. Jeremy removed the affected pin terminal and after a close inspection with no damage found, reinstalled the pin back into the connector and heard it click into place. A confirmation test of the CAN resistance showed a normal 60 ohms. He then reconnected the battery, started the vehicle and verified all the warning lights previously illuminated cycled off normally. Jeremy’s post-repair road test revealed no further concerns confirming a sound repair. In appreciation for going the extra mile and sharing his experience with us, Jeremy will be receiving the following from his Field Service Engineer: $500.00 Snap-On gift card ©2020 Subaru of America, Inc.

Congratulations and THANK YOU to our June 2020 QMR of the Month Award recipient! August 2020 TechTIPS Page 2 of 8 This series features TechTIPS articles frequently referred to by Techline. This month’s feature is from September 2009. 01 Cell Phones, Air Tools and the Techline In previous issues of TechTIPS, we published an article called “Calling the Techline… Can You Hear Me Now?” This month, we would like to pass along some reminders and reiterate a few very simple requests. We all know how the use of cell phones has become second-nature to most of us and an essential “tool” for getting things done. Unfortunately, reception issues are still prevalent which makes it hard for us to hear you (or for you to hear us). If you are going to call the Techline on your cell phone, please make sure you are in an area where signal strength and/or background noise are not issues, as it is frustrating on both ends when information has to be repeated. Additionally, calling us while standing near a co-worker who is using an air tool makes things particularly “challenging” on our end. NOTE: For obvious safety reasons and certain state laws, Techline reps will NOT talk to Technicians using cell phones while driving a customer’s car. 10 Recovery of Contaminated R-1234yf The Robinair® Models AC1234-6 and AC1234-9 are designed and certified to SAE J2843 HFO-1234yf Recovery/Recycling/Recharging Equipment for Flammable Refrigerants for Mobile Air Conditioning Systems. The machine is designed to recover and recycle R1234yf refrigerant, evacuate air after the system has been open, and recharge refrigerant. The new regulations require that a refrigerant identifier be part of the equipment which prevents recycling or evacuation of contaminated refrigerant. Either Robinair® machine will identify the refrigerant of the vehicle being serviced during all procedures. This includes; diagnostic pressure checks, evacuation, and re-charging. The identification procedure cannot be circumvented. If contaminated refrigerant is detected, a separate evacuation machine and storage tank must be used to clear the machine and the subject vehicle. HFO 1234yf must be at least 98% pure before the machine will recycle the refrigerant in a vehicle. Continued on the next page August 2020 TechTIPS Page 3 of 8 Continued on the next page 10 Recovery of Contaminated R-1234yf (CONTINUED) NOTE: Recovery tanks for contaminated refrigerant are gray with a black top. When the system identifies the refrigerant is contaminated, a special procedure is required for recovery. Please use the Instruction Manual for the Robinair® AC1234-6 or the Robinair® AC1234-9 for specific instructions on how to recover the contaminated refrigerant. 12 Water Leaking Into Cabin From Door Trim- All Models and Model Years When a customer is concerned with water dripping from the door panel to side-sill or into the vehicle, do not overlook the sealing cover installation. Gaps in the cover’s sealant can create a route for water to escape. This condition has been identified on all four doors and in some cases multiple doors on the same vehicle. When encountering this condition, first verify the door drain is free and clear by water testing. Water test with the window glass fully closed and the door open. Pour water down the glass from the outside of the vehicle. There is a small drain hole at the bottom of the door that water should drain from. If it does not, clear the drain and test again to confirm if debris blocking the drain was the only concern or not. After water testing the door and verifying the drain operates as designed, CAREFULLY remove the door trim panel and visually inspect the sealing cover. If inspection finds any gaps in the sealant, do not replace the sealing cover. Instead repair the condition by carefully removing and reinstalling the sealing cover (making sure to apply even pressure around the parameter of the cover) then visually verify there are no remaining sealant gaps. A final water test will confirm the is repair. August 2020 TechTIPS Page 4 of 8 12 Water Leaking Into Cabin From Door Trim- All Models and Model Years (CONTINUED) 15 Remote Engine Start/ Power Rear Gate Inoperative on Push to Start Vehicles When presented with a customer concern of the Remote Engine Start (RES) not working, or the Power Rear Gate (PRG) is inoperative with the engine running, be sure to inspect the Park Position Switch and signal to the BIU. This concern may not always be easy to spot as a Push Start vehicle will still be able to be started, even if the BIU is not reading the correct input. When the RES is activated, the control module checks the BIU input of the Park Switch before it will operate. If it does not see this, the RES will fail to start the vehicle. Check the BIU P SW reading in the live data. Likewise, the PRG looks for this P SW signal from the BIU to activate while the engine is running.
