03 NO MOVEMENT AFTER VALVE BODY REPLACEMENT ON 10-12 LEGACY/OUTBACK CVT

Techline has received calls regarding no vehicle movement after valve body replacement on the first generation CVT (TR690). After investigation, it was determined the valve body was installed without transferring the primary pressure pipe. Loss of hydraulic fluid pressure will result along with several DTCs, most commonly P0841 and P2746. When removing and installing a new valve body, the primary fluid pressure pipe will need to be transferred to the new valve body. Typically, the pressure pipe will be found in the original valve body. New O-rings are required to be installed when the pressure pipe is removed during valve body service. Figure 1 shows the oil pump pick up and the primary fluid pressure pipes. Servicing the oil pump pick-up tube is not necessary, other than verifying it is fully seated into the CVT case. Refer to the applicable Service Manual for the valve body removal and installation instructions.

06 EYESIGHT REPLACEMENT PARTS

The Techline has received multiple reports of stereo cameras being returned with issues of spider webs and debris on the hood assembly. Remember, these parts are serviceable for generation two eyesight systems, this would be 13-14 MY Legacy/Outback and 14-16 MY Forester.

Once you have removed the lens hood assembly from the camera following the procedures in the applicable Service Manual, determine if the webs have contacted the lens itself as shown in the photo on the right. If they have, the lens hood must be replaced. If the webs can be remove without touching the camera lens, CAREFULLY  remove them and reassemble the camera. IMPORTANT  : Always confirm proper system operation before returning the vehicle to the customer. Refer to the Service Manual or the EyeSight and Keyless Access with Push-Button Start (Module 923) Technicians Reference Booklet on STIS for further diagnostics information. Damage caused by outside influence is not a matter for warranty.

14 PRECAUTIONS WHEN USING THE DST-I BOX

When using the DST-I box, it is very important to first disconnect the Data Link Connector from the vehicle when you are finished. Otherwise, if you disconnect the connector from the DST-I box while the Data Link Connector is still plugged into the vehicle's diagnostic connector, it can set false CAN Communication codes in certain control modules. If this is not noticed by the Technician, it may lead to unnecessary repairs being performed at a later date due to the stored Diagnostic Trouble Codes. If you should accidently do this, be sure to check each module and delete any stored DTCs. This will not create any vehicle issues, it will just store the CAN Codes.

Another area of potential concern is the storage of the cable itself. As with previous Subaru Select Monitors, do not put stress on the harness near the connector ends by wrapping it around the DST-I box. Over time, this can lead to poor terminal contact and eventually broken wires.
