This month’s feature is from February 2021. 15 CP 1.0/1.5 Software Version Verification Reminder: For infotainment related concerns please always remember to review the “Forms and Downloads” Gen 4/Denso tab on Subarunet. All TSB’s related to each head unit are listed on their respective tabs. TSB 15-259-20R “Denso Gen 4 Cockpit One (CP1) Infotainment System Operating TIPS Technical Support Guide.” TSB 15-304-22 “Procedure for Techline Infotainment Concern Data Collection and Sharing via TechShare” When confirming CP 1.0/1.5 system software version information, it is critical to allow the unit to finish the boot-up process before accessing the version information screen. Failure to allow the process to complete could result in missing version information or asterisk symbols (****) as shown below. A good practice would be to wait a minimum of 3 minutes after the boot-up process begins at key on for this information to load properly. January 2023 TechTIPS Page 4 of 12 Continued on the next page 15 CP 1.0/1.5 Software Version Verification (CONTINUED) However, this should not be confused with no “RAD_SW” version and “DSP_FW” version displayed or showing asterisk symbols (****) AFTER waiting for the system to completely boot-up. That would be a sign of a failed software update. For more details see Subarunet announcement “Recall WRH-20 / WRI-20 Denso Gen 4 CP1 software update. Critical points to avoiding unnecessary hardware replacement” posted January 5, 2021. Note: “Deck” version as asterisk symbols (****) is normal when a CD Player is not installed. 07 CAN Communication Diagnosis – Where To Start? When diagnosing a LAN system, it is important to understanding how the system works. LAN system diagnosis can get overwhelming, it is important to start with the basics. Always verify the Select Monitor and interface module/cables are in good working order, and know the type of system you are working on. Begin the diagnosis with an all-DTC scan, can we communicate? If yes, what modules can we communicate with? What codes do we have and are they current? If we can communicate with all modules and have history U-codes, the issue may be intermittent and not currently present. At this point it is important to analyze what systems are setting codes and what modules they cannot communicate with. If there is an issue with the CAN system, determine which bus the fault is on. Do the codes all indicate one specific module, or multiple modules all from the same bus? If the codes are current and we cannot communicate with those indicated modules, or we cannot communicate at all, it is important to adjust your diagnosis accordingly. If there is no communication with the vehicle at all, but the vehicle does not seem to indicate any issue (i.e.: rough running, warning lights) there may be an issue with the scan tool connecting or the data link connector circuit. Does the SSM connect with other vehicles? Do we have a good connection at the OBD port? Is the DLC circuit missing anything? Verify power and grounds. If no problems are found, inspect the CAN circuit resistance at the DLC. Do we have the correct resistance reading based on the service manual specification? January 2023 TechTIPS Page 5 of 12 Continued on the next page 07 CAN Communication Diagnosis – Where To Start? (CONTINUED) Older model specifications may be 52-62 Ω (CAN C) while newer models may be 114-126 Ω (Diag CAN). Always verify what type of system you are working on. On models equipped with K-Line, this is a one wire communication, Verify no open to the next closest module, no short to ground/power. Often on a system with a faulty K-Line, aftermarket scan tools will communicate. If no communication is possible, but there is a clear issue of system failure, inspect each bus individually. On systems with Diagnostic CAN, you will need to access the network at one of the modules on the bus. Verify the module of the connector you are using does not have a terminating resistor as this will affect your results. Refer to the “CAN communication circuit check” found in the service manual. The all-DTC scan will tell us which modules cannot communicate with each other. Then inspect the circuit between those modules. If every module on a given bus is down, the harness could be shorted to power/ground. If the harness is ok, the issue could be a faulty module pulling the bus down. Disconnecting each module until communication with the other modules is restored is a quick check. If communication to only one module is down, verify that module has power and ground supply and a good connection to the CAN circuit. If all tests ok, the module itself may need replacement. Always verify no aftermarket accessories wired to the CAN system, or wiring repairs outside Subaru recommendations. Continued on the next page January 2023 TechTIPS Page 6 of 12 07 CAN Communication Diagnosis – Where To Start? (CONTINUED) “The Subaru warranty manual dictates that the harnesses must be replaced if any physical damage occurs to CAN B or C wiring (Twisted pair) under warranty. Outside of the warranty period, customer pay repairs to the wiring may be performed. Industry standard repair procedures must be used. Following the procedure listed in STIS. The proper twist must be maintained and the length between CAN high and low must be maintained to ensure message synchronization.” NOTE: Review the terminators for each CAN circuit. The DLC (Diagnostic) CAN includes one terminating resistor (120 ohms). The DLC is no longer connected in parallel to any CAN circuit. Measuring Powertrain CAN or Body CAN total circuit resistance at the DLC is no longer possible. For more diagnostic information refer to the Vehicle Communications Technician Reference Booklet and October 2021 TechTIP. The Vehicle Communications TRB is an excellent resource for understanding and diagnosing communication concerns. 07 BIU Replacement TIPS and Destination Setting When installing a new Body Integrated Unit (BIU), it is important to verify the correct steps to perform. It is always recommended to follow the Service Manual procedure on how to program and register the BIU. There could be some confusion on models that require a destination code entry. The first letter indicates the country, such as U4 = U.S., and C0 = Canada. In every case, a U.S. vehicle will require a U400 entry. If communication to the original BIU is possible, it is always recommended to use the read/write function with the SSM. If the incorrect destination code is input, it cannot be changed back. Please see previous TechTIPS concerning other issues and info when registering a BIU. 03/05 – A-Type BIU Replacement 05/11 – Remote Trunk Release Inop After BIU Replacement 10/13 – BIU Replacement on Push-button Start Vehicles 01/15 – (BIU) Replacement/ Interior Lights Flashing 09/20 – Replacing B/G-Type BIU Continued on the next page January 2023 TechTIPS Page 7 of 12 07 BIU Replacement TIPS and Destination Setting (CONTINUED) 12 20MY+ Legacy/Outback Manual Adjustment of Power Seat After Motor Failure It has been found that on MY20+ Legacy/Outback, the bolts to remove the seat can only be accessed with the seat position adjusted to a specific position. In a scenario where the slide motor fails and this postion cannot be achieved, there is a manual adjustment that can be made to expose the bolts to remove the seat. Further information can be found by viewing QMR TS-215498. The rear in-board mounting bolt is now vertical as opposed to previous generations that were installed at an angle. As a result the seat needs to be in a forward postion to access. Continued on the next page January 2023 TechTIPS Page 8 of 12 20MY+ Legacy/Outback Manual Adjustment of Power Seat After Motor Failure (CONTINUED) 12 If the slide motor is not able to be used to move the seat in the forward position, there is a T20 TORX head bolt at the front of the seat rail/frame that can be used to move the seat manually forward and back. The T20 Torx bolt for adjustment is on both the left and right hand seat rails, one bolt will move the seat forward and the opposite bolt will move the seat backward. NOTE: This function is available on both the passenger and driver side front seats with the power seat option. If the motor to raise and lower the seat bottom fails, there is no manual ‘adjustment screw’ available. The technician will need to remove the seat side cover and physically unbolt/remove the motor. Continued on the next page January 2023 TechTIPS Page 9 of 12 12 Accessory Catalog Update The Accessory Replacement Catalog found on Subarunet will no longer be updated with ‘23+ model year vehicles. Technicians often use this to find and verify parts numbers for Accessories. This information can now be found in the Snap-On parts catalog and on Subarunet “Application Charts/Pricing” tab in the location shown below: Continued on the next page January 2023 TechTIPS Page 10 of 12 SXM Preset channel logo blank on CP 1.5 equipped vehicles, ’23 MY Outback/ Legacy & Ascent 15 On all vehicles equipped with a CP 1.5 head unit (’23 Legacy/ Outback/Ascent) the SXM channels presets will not show the specific SXM channel logos when the vehicle is new. This is a normal condition. This condition is due to the head unit not receiving any SXM signal. While the vehicle is in transport to the retailer the backup fuse is not installed. The head unit does not turn on or receive power until the backup fuse is installed during the PDI procedure. It will take 4-6 hours of the vehicle receiving SXM signal (key on, engine running) for all the SXM channel logos to appear. Do not replace any parts for this concern. Most vehicles will not have enough run time for the SXM channel logos to appear when the vehicle is delivered to the customer. This is a normal condition. The presets may not appear if the vehicle is only driven short distances or operated in an area with poor SXM signal. The vehicle does not need to be operated for 4-6 hours at one time for this to complete. The SXM channel logos may start to appear slowly and one at a time. This is a normal condition. If this concern is present after 6 hours of the vehicle being operated in a known good SXM signal area, please refer to TSB 15-304-22. Collect a data log, all other requested information and submit an Infotainment case using Techshare.
