01 LOST KEYS? CONTACT THE SUBARU TECHLINE. UPDATED IMMOBILIZER CHART
If you receive a vehicle from the customer where all their originally registered keys have been lost, contact the Subaru Techline for the necessary steps to program new keys. Depending on the immobilizer type, you will be unable to just program one key without an original key. All immobilizer types (except for A type) require an original key to make any changes to the immobilizer system. Without an original key, a new one cannot be added. Unsure of which immobilizer type you have? Refer to the reference chart below. Once you have confirmed the vehicles immobilizer type perform the following:
- Verify the vehicle is onsite.
- Open a Repair Order with all necessary information.
- VIN, RO number, RO date, Mileage (if it can be obtained), etc.
- Verify key type (push button, turn-key)
- Contact the Subaru Techline.
When calling the Subaru Techline, please ensure all necessary information is available at the time of the call.
SOA will no longer clear immobilizer modules for POLK branded title vehicles (except for lemon law buy-back.) All other POLK branding will require immobilizer component replacement. Refer to the Title Alert when checking the Vehicle Inquiry on Subarunet. Please refer to the Service Manual/Registration Manual for Immobilizer for repair of these vehicles.
Anytime a retailer has a vehicle with lost keys a NEW Techline case must be opened for EACH vehicle. The retailer will not be allowed to reuse the document sent for other vehicles.
When Techline has components to clear, it is vital a completed form is sent. Without this information the entire process will be delayed. Specific components have different procedures for clearing and without this information the components may not be cleared at all or additional down time may occur to determine their origin.
07 CHECK BOARD HARNESS DIAGNOSIS
Every year more and more vehicles require check board harnesses to complete proper diagnostics. Recently, Techline and Field Quality Assurance have become aware that Technicians are not using these diagnostic tools correctly.
Modern vehicle wiring has gotten smaller. It is more important than ever to use the dedicated Check Board Harness for testing. There is potential to damage the vehicle's wiring harness if the proper testing procedure is not followed. Failure to do so can lead to new concerns caused by damage to the harness or module. It is good practice to mark/identify the testing portion of the Check Board Harness so one end is used for testing while the other end is reserved for plugging into the vehicle. This will prevent possible damage to the vehicle while perform testing and diagnostics.
The Service Manual will display a caution note if a Check Board Harness is necessary. The CAUTION/NOTE tab can also be used to identify the need for check board harness.
15 2022 WRX CID IDENTIFICATION
The new 2022 WRX has two base model options for CP1. The Cockpit Information Display (CID) can be easily misidentified when attempting to make repairs. The main method to determine which CID is installed is to inspect the Heated Mirror Switch on the bottom left-hand corner of the unit. Note in the pictures below if a heated mirror option is equipped it will be shown on the button.
The part numbers are also different, and the CID should not be interchanged with the opposite unit. The part number has now been included on the back of the unit if there is an unusual circumstance.
15 DETERMINING A COCKPIT INFORMATION DISPLAY FAILURE
Techline has identified four examples of failed CID (Cockpit Information Displays). These are the typical concerns of a failed CID.
- Figure 1: shows a thin pixel line across the screen at all times. This can develop anywhere on the screen.
- Figure 2: shows full color failure. The screen will always look disfigured and unusable.
- Figure 3: is a different variation of color failure, it will look patchy or as if the back light has failed in certain spots.
- Figure 4: is a total loss of image. This condition should not be confused with temporary blackout . This condition will not power up the screen in any way regardless of key position or input. Note that Airbag indicators still function. Volume and Temperature controls may still work if the blower is on at the time. Power and ground should be verified, and then the best course of action is swapping the CID with a known good unit of the same trim level (mid or high).
It is important to note that the following conditions are NOT Cockpit Information Display related.
- Freezing, system lag, or rebooting
- CarPlay® or Android Auto® App concerns
- Software upload or initialization error
- Volume concerns or no sound
- Auxiliary Component concerns: Aux port/USB, DMS, Back-up Camera, CD player, Microphone, Eyesight warnings.
- Programing Voice Recognition, Navigation, Loss of Presets, STARLINK®, Gracenotes®, AM/FM, SXM, or Clock concerns
These concerns should be diagnosed accordingly to the available reference material in STIS or the following Technical Service Bulletins.

- CP1 Microphone testing Procedure 15-275-20
15 POOR BLUETOOTH QUALITY CONCERNS
Techline has seen an increase in concerns reported regarding poor Bluetooth quality during phone calls across both CP1 and Harman models. These concerns stem from settings being mistakenly changed in the radio. Misidentification of these settings can lead to unnecessary Headunit replacement, DCM replacement or Microphone replacement when the root cause of the concern is simply a setting. The customer may describe the condition as any of the following:
- "Intermittently, the person I am calling cannot hear me at all".
- "There is a lot of wind noise during Bluetooth calls".
- "There is a lot of audible feedback during Bluetooth calls".
On Harman models, if the setting Microphone Volume is turned up or down, these conditions can occur. The setting has very little to do with the loudness of the call. In actuality it adjusts how sensitive the microphone is. A Microphone Volume with a +30, will have a lot of "wind noise" or static. The microphone is too sensitive and is picking up every noise inside the cabin. If the setting is -30, the caller will not be heard at all when talking. Small adjustments can be made in one or two increments, but Techline has not seen a phone that requires more than 4 adjustments.
On Denso CP1 models, if the setting Call Volume is set to more than +/-2, the same condition can occur. Techline usually finds that the Call Volume has been turned up to +6 which creates the same conditions listed above. Some phones may require a +/- adjustment. However, Techline has not seen any models that need more than +1 to make the Bluetooth clear. Here is a picture of Base model CP1 and Mid/High CP1 for reference.
15 GENERATION 4 EYESIGHT CAMERA REMOVAL AND INSTALLATION
Generation 4 eyesight cameras have a new procedure for removal and installation. It is important to take care when removing and installing components as improper removal and installation practices can damage camera or windshield. The Eyesight cover, heater elements, and camera on the generation 4 system has been designed to snap onto a camera bracket that is bonded to the windshield. If the bracket is damaged the entire windshield must be replaced . The components have been engineered to be removed by hand. Do not use impact tools when servicing the eyesight camera components.
After removing the overheard console, the Eyesight cover is removed by applying pressure on the back of the cover to slide it forward. The technician should only try to release one side at a time. While applying moderate steady pressure to the back of the cover the technician should be applying pressure to the front of the cover to limit the travel when the tabs release. If the cover is not secured while being released, locating pins on the camera bracket may be damaged. Once the cover has been released from the clip on one side, the technician should perform the same procedure on the other side. The picture below shows the direction that the cover is removed. The lower section of the image shows the position of the heater locating pin. The lower right image shows where the improper removal of a cover resulted in the pin being broken off. Damage to the bracket or pin(s) can only be repaired through windshield replacement.
The camera has 3 mounting pins that engage the windshield bracket. A forward-facing locating pin is located centrally on the front of the camera and there two pins in the rear of the camera. The camera is removed by applying steady pressure in a rearward motion until the tabs are released. Only attempt to release one tab at a time or damage to the bracket may occur. When reinstalling the camera, the use the center pin to locate the camera. Then seat the camera on the bracket using one of the rear pins. Apply steady pressure to each pin. There will be an audible click when each clip is seated. Attempting to secure every pin at the same time can result in damage to the windshield bracket. Any damage to the bracket will require the windshield to be replaced.
