May 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: Cory Calp from AutoNation Subaru in Cockeysville, MD The winning QMR of the Month selected from March’s submissions involved the diagnosis and repair of a 2019MY Ascent with a Check Engine light that came on during the State Inspection road test. Cory began with a DTC check and found P0230: FUEL PUMP PRIMARY CIRCUIT stored in the ECM memory. After gaining access to the fuel pump controller, he noticed over time with the vehicle running, the unit became abnormally warm to the touch. He then proceeded with numerous wiring checks to verify proper voltages, solid grounds, voltage drops and resistance values. When testing the signal wire from the fuel pump controller, there was no output voltage at all to the ECM. Cory used the SSM4 oscilloscope function to check for the controller’s square wave signal which was not occurring. He ordered a new controller and after installation, confirmed the square wave signal was within the specification supplied in the Service Manual I/O Signal Chart. Subsequent post-repair road tests confirmed the successful repair. Cory’s report included details of each connector / pin test performed along with the results and a series of quality photos to support his findings. In appreciation for going the extra mile and sharing his experience with us, Cory will be receiving the following from his Field Service Engineer: $500.00 Snap-On gift card SUBARU TECHLINE HOLIDAYS & HOURS OF OPERATION 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 March 2021 QMR of the Month Award recipient! Continued on the next page May 2021 TechTIPS Page 3 of 10 This series features TechTIPS articles frequently referred to by Techline. This month’s feature is from July 2018. 01 Understanding DTCs and How to Proceed Properly with Repairs The Techline has been receiving calls from Technicians who in some cases are following the wrong trouble tree when diagnosing DTCs. When a vehicle comes in with multiple codes stored, always look at the Freeze-Frame (FF) data and the Time Count PID first. This will be the best place to get a direction as to what the first DTC to set in the affected system was. IMPORTANT: Never clear any DTCs until all have been recorded and the corresponding FF data saved electronically. In the example below, a customer came in with a traction (VDC) light, Check Engine light and A/T Temp light on. If the root cause issue is not current, they could come in with no warning lights on at all. The Technician connects the SSM and the following DTCs are stored: • VDC code C1424 (ECM failure): DTC indicates there is a code in the ECM. • ECM code P0700 (AT request MIL on): DTC indicates there is a code in the TCM eBay . • TCM eBay code P0841 (Secondary Pressure Sensor Malfunction): This DTC is the root-cause issue and should be the code the Technician diagnoses first. In this case, the other codes (C1424 and P0700) are secondary codes. The TCM eBay informed the other control modules of its failure by setting the P0841. Whenever a control module has an issue and stores a DTC, there is a strong possibility of DTCs in other modules due to the interdependence of one system on another through operation of the high-speed CAN system. You may also see CAN communication codes stored. These DTCs should be interpreted as secondary or by-product codes unless there are no other codes stored. Always check each system for DTCs as once the issue has subsided, the only place the DTC will be stored is in the affected system. An All-System scan will only provide current codes which in the example above, would be C1424. 05 AWD light flashing, STI & WRX As the seasons change, WRX & STI owners often swap their wheels and tires for a summer/winter set. Techline has seen an increase in calls about a concern of the AWD light or DCCD light (model specific) flashing and being inoperative above certain speeds. This concern has been traced back to excessive road force in the wheel and tire assembles interfering with the center differential control system. If you encounter a WRX or STI that the AWD light starts flashing when a certain speed is reached, with no DTCS or obvious signs of damage, be sure to inspect the wheels and tires. You may find that the customer has recently installed seasonal tires. At this point, a road force balance should be performed. Continued on the next page May 2021 TechTIPS Page 4 of 10 05 AWD light flashing, STI & WRX (CONTINUED) Remember, the suggested road force for a passenger tire on a Subaru is 8.0kg (17.6lb) or less as per the NVH bulletin 05-50-10R. Exceeding these values could cause this condition. If the wheel and tire assemblies test near this specification, swapping/testing with a like vehicle is recommended. 07 WRE-21 Ignition Coil Connector Removal and Wire Clip Loss- How to Repair Techline has received reports of some retailers calling and looking for the metal retaining clip from the ignition coil connector on the engine harness. Technicians are prying the metal retaining clip off to remove the connector from the ignition coil. This is the incorrect and improper way to disconnect the connector. The metal retaining clip should not be removed in order to disconnect the connector from the ignition coil. The metal retaining clip should be pushed down, and the connector pulled off from the ignition coil. This information is in the Service Manual and was added as an update in the WRE-21 bulletin. It is provided here as reference. The metal retaining clip itself is not available separately. If the clip is lost the connector will need to be ordered. The new connector comes with the metal retaining clip installed as shown here. Supply of these connectors is extremely limited and must be special ordered. Retailers need to order these connectors only as needed using the existing VOR parts order process. They must then contact the PICs team, after placing the VOR order, to have the connector(s) released. Continued on the next page May 2021 TechTIPS Page 5 of 10 10 20-21MY LGY/OBK, “Setting temperature shift” in A/C CM customization A customer may present a concern of their climate control vent temperature seems too hot or cold in relation to the settings they are choosing. Technicians should be aware of several factors contribute to the setting being chosen; blower motor speed, the difference between ambient temperature and target temperature, and the effect of the sun all play a role to a person’s perception of temperature inside the vehicle. Using the SSM4 a Technician has the ability to adjust/customize the target temperature in order to compensate and adjust the final vent temperature perceived by the customer. By adjusting the setting temperature target value, Technicians can raise or lower the final vent temperature to provide the customer with what they believe to be a more accurate final temperature. The customization in the SSM4 for the target value can be adjusted from (+)3 to (-)3. This is not a direct relation to degrees, but levels. It is important to note, changing the target value will also change the blower motor ramp settings. The customer may notice the fan does not operate with the same characteristics as it did before the adjustment. This is a normal operating condition. The A/C CM controls the blower temperature/speed in order to reach the target temp. This will also be affected depending on the gap between the target temp, actual temp and outside temp. The fan may initially blow higher and stronger to acquire the target temp selected. Depending on parameters, this may also create an overshoot scenario in which the customer may feel the system is too hot/cold. This is also a characteristic of how the system operates. It is important to note the A/C CM judges the vehicle temperature unit by using the destination set in the Combination Meter (Canada or US) and will adopt the proper temperature unit: Celsius or Fahrenheit. When monitoring the A/C CM live data, the control panel setting values do not have a unit. This is simply showing the range in degrees available for both Celsius and Fahrenheit.

Techline recommends a thorough customer interview and possible test drive to understand the customer’s temperature perception. Example: If the customer believes when their vehicle is set to 70°, it is noticeably colder to them, the target value can be adjusted to a higher (+) target temperature. This in turn, will raise the vent temperature for the effect of 70º, but in actuality, be above 70° depending on the setting shift. Conversely, if they feel 70° is hotter than it should, lower the setting temperature shift. The steps to perform the customization can be found on STIS > Diagnostics > Air Conditioning (Diagnostics) > Customize > Operation.
