October 2021 TechTIPS Page 1 of 11 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: John Cote from Bill Kolb Jr. Subaru in Orangeburg, NY The QMR of the Month selected from August’s submissions detailed the diagnosis and repair of a recurring DTC B281E related to the Reverse Automatic Braking (RAB) system on a 2018MY Impreza. After confirming the RAB warning lamp operation and connecting the SSM, he was unable to communicate with the RAB system and found no other DTCs present. Another Technician had already replaced the RAB control module on a prior visit but unfortunately, the condition returned shortly thereafter. After John confirmed all the related power and ground wiring was in order, he turned his attention to the CAN system. By split-halfing the CAN harness between the EyeSight stereo camera and the RAB module, he was able to duplicate fluctuations in the resistance readings when wiggle-testing the R180 CAN joint connector. John replaced the left (driver) side body harness and after checking his resistances again postrepair, normal values were restored along with communication between the RAB module and EyeSight stereo camera. The DTC cleared normally with no recurrence during his road testing. John’s report outlined the diagnostic steps used, his test results and included a video of his DVOM while testing the affected joint connector. In appreciation for going the extra mile and sharing his experience with us, John will be receiving the following from his Field Service Engineer: $500.00 Snap-On gift card SUBARU TECHLINE HOLIDAYS & HOURS OF OPERATION Thanksgiving: (Closed) Thursday, November 25, 2021 Day After Thanksgiving: (10:30AM – 3:30PM) Friday, November 26, 2021 Holiday Break: (Closed) Friday, December 24, 2021 Saturday, December 25, 2021 Monday, December 27, 2021 Friday, December 31, 2021 Saturday, January 1, 2022 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 August 2021 QMR of the Month Award recipient! October 2021 TechTIPS Page 3 of 11 Continued on the next page This series features TechTIPS articles frequently referred to by Techline. This month’s feature is from October 2020. 01 CPO Procedure for Turbocharged Subaru Vehicles Techline has observed a surge in Certified Pre-Owned (CPO) submissions with the increased number of turbocharged engines across multiple platforms. As part of the CPO program, turbocharged vehicles require the Calibration Identification/ Calibration Verification Numbers (CID/ CVN) to be checked before enrollment. Due to the high number of inquiries to Techline, we felt it necessary to remind retailers of the correct CPO procedures. To help serve retailers in a timely manner, please review the CPO process and expectations using the provided instructions below. Incorrect submissions will delay the process for all parties involved. Responses to CPO requests are returned within a 24hr time period. Holidays & weekends may affect return times. • Vehicles more than five years old ARE NOT eligible for CPO. • Checking the CID/CVN over the phone for CPO purposes is NOT the correct procedure. • Vehicles which are customer pay or used car inspections should not be submitted. Example: A customer wants to buy a 2017 STI privately, from the local used car lot. The customer brings the vehicle to the retailer to make sure it has not been modified. In this situation, the retailer should contact Techline and open a case to verify CID/CVN. • Vehicles that are at the retailer for warranty work, such as short block failure or check engine light diagnosis, should contact Techline. • Vehicles confirmed to be modified should be called in to the Techline, a case opened and a Vehicle Modification Report filed. #1 Vehicle Information Acquisition Screen Please be sure to obtain a clear, crisp image of the vehicle information acquisition screen. An example is shown below. Please DO NOT submit any hand written information. Vehicle Information Sheets (VIS) or a copy of the Repair Order (RO) are also unacceptable. This information should ONLY be obtained using the Subaru Select Monitor. Pictures taken with a cell phone are acceptable as long and the information can be clearly read.

Continued on the next page October 2021 TechTIPS Page 6 of 11 07 Diagnosing Network, U – Codes When a vehicle presents U-0XXX diagnostic trouble codes, there are several potential causes for the fault. Such faults have been attributed to soft connections, poor pin fitment, damaged wiring harnesses and failed control modules. These issues may also be caused by outside influence. A visual inspection of the vehicle for aftermarket devices and a customer interview should always be performed prior to diagnosis. After the vehicle has been inspected for physical damage or aftermarket devices, the Technician should perform a full system DTC scan. When reviewing the scan, look for common trends of modules not reporting, similar DTCs set across multiple systems, as well as faults indicating a possible voltage concern. When a P/C/B code is present related to voltage, it is possible low or no voltage could be the root cause for the lack of communication. Power and ground checks should be performed to the corresponding control modules affected prior to local area network testing. Once power and ground have been confirmed, the Technician should check for correlations between modules, i.e., who is reporting a problem or lack of communication. When a U-code occurs in more than one module, it can provide direction for where the fault may have occurred. Being able to identify this will help aid with diagnosis. Below is an example of a system scan and several U-codes. Sometimes it may be difficult to determine if a U-code is the root or the result of a problem. Freeze frame data, trip counts, and time stamps may be used to determine which faults happened first. This can also be useful in ruling out stored faults in the system but have not happened recently. The Technician should refer to the wiring diagram whenever there is a lack of communication. The electrical path should be established between the module not reporting and each module that is reporting the lack of communication. Common connectors and junctions should be inspected for pin fitment and soft connections. Next, using a DVOM, circuits should be isolated and checked for high resistance, short circuits, and open circuits while performing wiggle testing. Continued on the next page October 2021 TechTIPS Page 7 of 11 07 Diagnosing Network, U – Codes (CONTINUED) Here is another example: NOTE: DO NOT CLEAR codes to see what returns. If the problem is intermittent, the codes may not return resulting in diagnosis coming to a halt. Continued on the next page October 2021 TechTIPS Page 8 of 11 07 Parasitic Draw Testing, A Different Approach When checking for a parasitic draw, the Technician should be careful and mindful not to wake control modules in the vehicle. This is critical for an accurate diagnosis. Modules may be “awakened” if fuses are pulled and replaced when using an old-style diagnostic method. A more efficient way is to inspect the voltage present across each individual fuse when the parasitic draw is present. The Technician should prepare the vehicle by disabling any door, hood or trunk latch that may need to be opened during the diagnosis. Whenever possible, it is best to have two devices to help diagnose a draw: an amp clamp or a DVOM installed in series with the battery should be used to detect the draw and confirm the draw is present while testing. A second DVOM can be used to test for current flow across the top of a fuse. Place your DVOM into the mV setting and check across the top of each fuse individually. Note the measurement and location of the current flow. A millivolt to milliamp conversion chart may be used to get an accurate determination of how much current is passing through a fuse. Refer to the conversion chart for the specific diagnostic tool being used for the most accurate results. If the Technician does not have a conversion chart, the same measurement can be made by setting the meter to mA. However, the measurement will not show the actual current draw. The Technician would have to inspect the circuits with the highest mA readings. When the source of the draw is found, the Technician should reference the appropriate wiring diagram to individually inspect modules or components without disturbing the integrity of the rest of the circuit.

The following is an inspection procedure to check for for checking the presence of Auto Stop Eliminator using the CP1 CID control. • Turn off Auto Stop once and turn off the engine. • Start the engine • Confirm Auto Stop light is Green (see below) and stays Green. This is normal operation. If the system is equipped with an Eliminator, the light will be Green for a moment and then turn off. If an Eliminator is suspected to be installed according to the above procedure, an inspection of the EyeSight Camera harness will be necessary. Check to see if there are any extra/unnecessary harnesses around the eyesight connectors with the eyesight camera cover removed. 17 SRS Air Bag, Rear Seatbelt Chimes Techline has had an influx of calls pertaining to the rear seat belt chime activation on 2020 model year and newer vehicles. If the occupancy detection system (ODS) detects an object on the rear seat and the rear seat belt is not buckled, there will be an audible chime. There is no way to deactivate the rear seat belt chimes other than to buckle the rear seat belt. At this time, the vehicle software logic will not allow this feature to be disabled. Customers should be advised to keep the seat belt buckled when there are child seats installed and to stow other items in the cargo area.
