SERVICE PROCEDURE / INFORMATION:
(*1) Instructions on how to perform and read the OBD MODE test results. This procedure will be required when performing the diagnostic Steps outlined below.
Read the following data monitor values:
1. MID – $35 TID – $8B
2. MID – $35 TID – $8C
3. MID – $35 TID – $8D
4. MID – $35 TID – $8E
5. MID – $36 TID – $8B
6. MID – $36 TID – $8C
7. MID – $36 TID – $8D
8. MID – $36 TID – $8E
STEP 1: Are DTCs P0016, P0017, P0018, or P0019 displayed within the ECM fault memory?
NO – Perform the reprograming procedure outlined in STEP 2 ONLY. The service procedure is finished, no further action is required.
YES – Proceed to STEP 2 and continue to the proceeding steps.
STEP 2: Reprogram the ECM following the normal FlashWrite procedure.
Subaru of America, Inc. (SOA) highly recommends connecting either the Subaru Midtronics DCA8000 Dynamic Diagnostic Charging System or the Subaru Midtronics GR8-1100 Diagnostic Battery Charger to the vehicle and utilizing the Power Supply Mode feature anytime a vehicle control module is being reprogrammed. Once the Midtronics charger is connected to the vehicle, if the battery is fully charged, it takes less than three (3) minutes to boot-up the charger, select the Power Supply Mode, and have the battery voltage stabilized and ready for reprogramming.
NOTES:
- For instructions on using the Power Supply Mode, reference the applicable User Manual for the Midtronics DCA-8000 Dynamic Diagnostic Charging System and the Midtronics GR81100 Diagnostic Battery Charger on STIS.
- Confirm all electrical loads such as lights, audio, HVAC, seat heaters, and rear defroster are all switched OFF before setting up the charger for Power Supply Mode.
- Select the correct battery type (Enhanced Flooded, Flooded, Gel, AGM or AGM Spiral).
- Input the CCA which matches the vehicle’s battery. NOTE: OE and replacement batteries have different CCA ratings. Always confirm the battery’s CCA rating before proceeding.
- If using a DCA-8000 Dynamic Diagnostic Charging System, set the power supply voltage to 13.5 Volts.
- DO NOT connect the DST-i or DST-010 until the Power Supply mode function has completed its battery test mode and the Charging Voltage has dropped to and shows a steady 13.5 Volts on the display.
- Once Power Supply Mode reaches a steady 13.5 Volts, connect the DST-i or DST-010 to the OBD connector and proceed with initiating the normal FlashWrite reprogramming process.
- Amperage will fluctuate based upon the vehicle’s demand for power. NOTE: If the voltage rises beyond 14 Volts while programming is in process, the procedure will abort. This can indicate a need to test or charge the vehicle battery before any further attempt at programming is made.
- ALWAYS set the power supply voltage to 13.5 Volts when using Power Supply Mode. NEVER turn the ignition switch on when charging at voltages 15 Volts or higher.
REMINDER: If the DCA-8000 or GR8-1100 indicates the vehicle’s battery must be charged, charge the battery fully before proceeding to reprogram the vehicle while using the Power Supply Mode.
NOTE: Control module failures resulting from battery discharge during reprogramming are not a matter for warranty. Should any DTCs reset after the reprogramming update is performed, diagnose per the procedure outlined in the applicable Service Manual.
VERY IMPORTANT:
This information is applicable to the Subaru Midtronics DCA-8000 Dynamic Diagnostic ChargingSystem and the Subaru Midtronics GR8-1100 Diagnostic Battery Charger ONLY. It does not apply to any other brand / type of “generic” battery charger whatsoever. ONLY the DCA-8000 and the GR8-1100 and their Power Supply Mode feature have been tested and approved by SOA.
End of procedure for vehicles WITHOUT DTCs P0016, P0017, P0018, or P0019 store in the ECM.

Не давала мне покоя, ситуация которая началась, три недели назад, а именно Р1604 PCM Internal Dual Port Ram начало здесь www.drive2.ru/l/488893448317829185/ Перекурив кучу форумов и кучу комментариев по этой ошибке, все сводилось к замене PCM, оставалось только съездить на компьютерную диагностику, что бы так сказать услышать приговор специалиста из сервиса, хотя понимал что нового мне ни чего не скажут, потому что всю информацию сервисмены берут со страниц интернета, так же как и я.Но все же мы с себрингом терпеливо ждали дня, когда выпадет возможность съездить в сервис, в глубине души надеясь на чудо.Все это время себринг простоял в гараже, а я ездил на другой машине.И вот этот день настал…И так спустя три недели, я снова за рулем крайслер, ключ в замке, запуск… Чувствуется просадка напряжения подсевшего аккумулятора, в какой-то момент на миг загораются все сигнальные лампы на панели приборов, но тут же мотор запускается, привычно горит ЧЕК. Прогревается, едем, машина едет хорошо, и даже отлично, то ли отвык за три недели, то ли после 1.4 литрового Шевролет так кажется. По приезду как обычно это водится, мастер приемщик молча забрал ключи и загнал машину а бокс, но на этот раз я не стал сидеть в комнате ожидания, а остался в зоне ремонта и занял наблюдательную позу.
-У тебя кислородный датчик ошибку выдает — вылупился на меня мастер
-ЧТО? какой датчик? -потеряв дар речи спросил я
-Нижний правый — ответил мастер и со знанием дела покрутил ключом в замке
На панели приборов отчетливо высветилось Р0137, DONE.
-Где 1604? -ни чего лучше не придумав спросил я
-Не знаю, сейчас я подключу и посмотрим как датчик работает -деловито сказал мастер, воткнул сканер и застыл в позе греческого мыслителя.
Повисла пауза
-Ну да вот она- ожил мастер — но сейчас она не активна, датчик работает хорошо и даже отлично.
После этого мастер еще минут двадцать ходил от машины к компьютеру, что то смотрел, отсоединял фишки от мозгов, тыкал тестером в разные места, без конца заводя и и глуша машину, при этом приговаривая-
-Плюс есть, с питанием все нормально… —
После всех процедур, мастер толкнул такую речь
-Сейчас я тебе их удалил и они не появляются, может появиться, а может и нет, может кислородный датчик так повлиял на мозги, а может и сам РСМ.
И рассказал историю из жизни, про то, как оторваные об препятствие провода нижнего кислородного датчика полностью уничтожили РСМ
-Короче ездий пока -закончил мастер -880 рублей с тебя-
Еще полдня я ездил по делам, глушил и заводил машину, но Чек так и не загорался.Что это было и вернется ли снова так и осталось загадкой.Естественно казалось что машина просто нереально летит.Возвращаясь домой в приподнятом настроении, я думал про то, какая же все таки хорошая эта Американская машина Крайслер Себринг, сама ломается, сама чинится, это не какая-то вам японка, которая хоть и ездит десятилетиями без проблем, но если сломается то уже сама не починится ни когда.
P.S.Однако чудо продолжалось не долго, на следующий день P1604 сияла на панели приборов еще ярче, всем видом говоря что пора бы заняться поиском, другого PCM ФАГ!

Hello, I am new to this and I appreciate everyone taking their time to reply back and give me your input in order to help. So I bought this car with a blown engine and it had a bad ticking sound (https://www.vzmessages.com/vl/b9bdf2…2654c7eaf65713) as you can see in the link. Notice how the engine does not shake and it only has that loud sound. Well I bought it to a shop to get the short block replaced. I bought everything from Subaru. When we first fired it up it started shaking and backfiring and it still is. The code that is throwing are the following P0171, P0304, P0300, P1604. The car is not stock and it has the following mods done to it:

the brake cleaner sprayed on ‘the hose’ tells the entire story intake air leak this sucking in extra un-monitored air causing P0171 (Fuel Trim System Lean Bank 1) P0604 is likely unrelated |

Problem is that before changing the block to a new one it didn’t have any of those problems. That is why I am very confused. |

Yes, we understand. Now you have new problems. Changing the engine means you effectively have a new car, anything the old car did or didnt do is not relavent anymore. You start troubleshooting at the top, then work your way down: 1. Is everything installed correctly? Uni already skipped to it, based on what you are describing and your level of experience with cars, it would be best to take it to a reputable shop. You are not at a reputable shop based on the information you are writing here. |
