Chia Sẻ Cách Reset Cửa Khoang Hành Lý Forester 14+ Khi Không Đóng Mở Tự Động và Phát Ra 3 Tiếng Kêu Beep-Beep-Beep:
Có nhiều bác hỏi em cách reset hệ thống khi cốp sau Forester 14+ (trunk door) không auto đóng mở mà chỉ kêu 3 tiếng beep beep beep khi bấm nút rồi im re không nhúc nhích gì hết, hiện tượng này là do các trạng thái logic các sensor của PRG (Powr Rear Gate) không đồng bộ (do lúc thao tác, thường là bấm nút mở hơi lâu tí nhưng chưa đủ lâu để mở manual) dẫn đến hệ thống PRG system bị treo và hệ thống chỉ cho phép hoạt động đóng mở bằng tay (manual). Hiện tượng này có thể tự fix (DIY) trong 3 nốt nhạc bằng cách reset bình điện,khỏi mắc công chạy vào hãng chi cho tốn xăng.
Em tìm được tài liệu chính quy TSB từ Subaru gởi các bác tham khảo, bác nào gặp phải hiện tượng này mà chưa rõ cách fix thì cứ alô em hướng dẫn nhé

APPLICABILITY:
2014 Forester Models
SUBJECT: Power Rear Gate (PRG) Inoperative, Incomplete Initialization Procedure
INTRODUCTION
This bulletin provides additional information (see TSB 07-76-13R dated 7/8/2013) regarding the PRG system
operation and initialization procedure. If you receive a customer concern of a “beep- beep-beep” sound when
trying to operate the PRG, a likely cause is an incomplete initialization procedure. Initialization occurs any time
the auto closer function operates. It must complete every time the PRG is operated (closed) in order for the PRG
to work properly the next time one of the activation switches is operated. If a voltage drop occurs (e.g. cranking
the engine) during the exact time this initialization procedure is in process, there is a possibility the procedure
will not complete properly and (although securely closed and latched) the PRG system will be rendered
inoperative. During this time, the gate will operate manually however the PRG functions will be disabled. If the
customer’s normal usage pattern creates this condition regularly, a countermeasure PRG control unit has been
developed to remedy it.
COUNTERMEASURE IN PRODUCTION
The countermeasure PRG control module was incorporated into production during August, 2013 beginning with
E*492310.
PART INFORMATION The part number for the countermeasure PRG control unit is 63350SG003.
SERVICE PROCEDURE / INFORMATION
If the condition has been verified and can be duplicated, explain and demonstrate to the customer the operating
characteristics of the PRG system (e.g. wait to start the car until the PRG is fully closed). Starting the car with
the rear gate open is NOT recommended. This is to prevent exhaust gases from entering the vehicle’s passenger
cabin. If the customer understands how the system operates and is able to adjust their habits accordingly, no
further repair is necessary. Complete steps 1-3 of the initialization procedure outlined below. If normal PRG
operation cannot be restored or this condition occurs frequently for the customer, perform the complete
procedure, steps 1-7 to re-initialize the system.
1. With the ignition “OFF”, open the PRG manually using a fluid motion (no light flash or beep should
occur).
2. Carefully (slowly) close the rear gate until the first audible “click” of the rear gate latch mechanism is
heard then immediately let go of the rear gate. The auto closer function will then operate to complete the rear
gate closing / latching function. This will also complete the initialization process. If the auto closer function is
inoperative, diagnose per the applicable Service Manual.
3. After the PRG is fully closed, operate either the Gate Opener switch, the Gate Inner (close) switch, remote
keyless access switch or the Interior PRG Open/Close switch to verify the automatic opening and closing
operation.
4. If the PRG inoperative condition persists, record the radio station presets (and navigation system favorites,
if applicable).
5. IMPORTANT: Record any codes currently in PRG memory as the next step will clear them. 6.
Disconnect the positive and negative cables from the vehicle’s battery, touch the 2 cable ends
together creating a capacitive discharge which will clear the memory.
7. Reconnect the cables to the battery, reset all radio presets (and navigation favorites, if applicable) then
confirm normal PRG operation.
• If the customer’s PRG usage pattern precludes the ability of the system to initialize upon closing, and
control unit replacement is determined to be necessary to assure customer satisfaction, order and replace the
PRG control unit following the service procedure outlined in the applicable Service Manual.
• If the PRG still does not operate properly, utilize any codes pulled from the system and follow the rest of
the diagnostic procedures beginning on page PRG(diag)-2 of the
2014 Forester Service Manual.
