NUMBER: 15-273-20 DATE: 09/09/20 REVISED: 03/15/23 APPLICABILITY: 2020MY-2023MY Legacy & Outback 2022MY-2023MY WRX SUBJECT: Denso CP1 BASE (Dual 7” Display Screen) Erratic Operation INTRODUCTION: This Service Information Bulletin addresses isolated customer concerns regarding the pictured CP1 BASE Model Center Information Display (CID) LOWER 7-inch display screen flashing, not responding to touch inputs and / or shutting off intermittently. SERVICE PROCEDURE / INFORMATION: REMINDER: Customer satisfaction and retention starts with performing quality repairs. Use the reference table below for the procedure to help isolate the root cause and repair as applicable. STEP Check Items: Yes No 1 Inspect for any deformation of the lower touch screen surface. Look closely at the lower touch screen from various angles. Are there any wavy surface areas visible as shown in Fig. 1 below on the touch screen? Replace the CID Go to Step 2 2a / 2b Inspect for deformation of the touch screen, surrounding trim panel and for any foreign material trapped in between them. Can a folded dollar bill (2 thicknesses) be inserted 2mm into the gap between the top and bottom edges and 4mm into the gap on both sides of the surrounding trim panel and the lower touch screen? Perform these measurement tests TWICE. Go to Step 3 Replace the CID 3 After removing the screws from the instrument panel, is the touch screen still switching on its own (without any user input), flashing or shutting off intermittently? Replace the CID Test over time 4 Reassemble the IP. After reassembly, is the lower touch screen still switching on its own (without any user input), flashing or shutting off intermittently? Replace the CID Test over time SERVICE INFORMATION BULLETIN ATTENTION: GENERAL MANAGER q PARTS MANAGER q CLAIMS PERSONNEL q SERVICE MANAGER q IMPORTANT – All Service Personnel Should Read and Initial in the boxes provided, right. ©2020 Subaru of America, Inc.

Bulletin Number: 15-273-20R; Revised: 03/15/23 Page 2 of 4 Continued… INSPECTION PROCEDURE: Step 1: Check for deformation of the LOWER touch screen surface: Check for any deformation or waviness of the touch screen surface. Inspect the surface condition diagonally with light reflecting on it at various angles. Is any waviness visible as shown in Fig. 1 below? • If YES: Replace the CID display component because the surface of the touch screen is deformed. • If NO: Proceed to Step 2. NOTE: In the event the CID requires replacement, the new unit INCLUDES a new surrounding trim panel and new control buttons as a ready to install assembly. Steps 2a & 2b: Inspect for deformation of the lower touch screen, the surrounding trim panel and for any foreign material trapped in between them. Use the illustrations below as a guide. • 2a: Insert a (preferably a crisp, new) dollar bill into the gaps between the touch screen and the surrounding trim panel along the top (A) and bottom (B) as shown in the Fig. 2 example below. The dollar bill should be able to be inserted 2mm into the full width of both the top and bottom gaps. • 2b: Insert a dollar bill folded in half (to provide 2 thicknesses) into the gaps between the touch screen and the surrounding trim panel along the sides (C) & (D). The folded dollar bill should be able to be inserted 4mm into the side gaps from top to bottom. IMPORTANT: All 4 of these measurement checks must be done TWICE. Bulletin Number: 15-273-20R; Revised: 03/15/23 Page 3 of 4 Continued… • If the dollar bill can be inserted into the gap 2mm on the Top and Bottom and 4mm on BOTH sides, there is no deformation of the touch screen or surrounding trim panel. Proceed to Step 4. • If the dollar bill cannot be inserted, replace the CID because the surrounding trim panel and / or touch screen are likely deformed. Step 3: Can any of the conditions “Display flashes, does not respond to touch inputs, or shuts off intermittently” be duplicated: • If YES: The condition persists, proceed to Step 4. • If NO: The condition no longer persists. Operate the unit for an extended period to confirm a successful repair. Step 4: Check condition of the retaining screw holes and contact surfaces between the instrument panel (IP) and CID after removing the screws. a. Inspect the screw holes of the IP and the bracket following the illustrations below. If the screw hole(s) are overlapped, CAREFULLY re-align to Acceptable or “OK” as shown below. b. Inspect the gap between contact surfaces of the IP and the bracket following the illustration below. If a gap exists between the two contact surfaces, CAREFULLY adjust the seating / alignment by changing the tightening order of the retaining screws. Bulletin Number: 15-273-20R; Revised: 03/15/23 Page 4 of 4 TIP: If there is too much mis-alignment, CAREFULLY loosen the other three screws, let things settle, then try tightening them again in a different order to see if the alignment improves before installing the final screw or, loosen them all, let things settle then tighten again but in stages so any one hole is not too far offset (beyond OK). Can the conditions “Display flashes, exhibit “ghost touch” operation as per 15-295-22, does not respond to touch inputs or shut off intermittently” still be duplicated? • If YES: The condition persists, replace the CID. • If NO: The condition no longer persists. Operate the unit for an extended period to confirm a successful repair. IMPORTANT REMINDERS: • SOA strongly discourages the printing and/or local storage of service information as previously released information and electronic publications may be updated at any time. • Always check for any open recalls or campaigns anytime a vehicle is in for servicing. • Always refer to STIS for the latest service information before performing any repairs.
