Вопрос по схеме, Что за блочок и что делает?

Помоему отошли от теми!
Вот что тот же самий Митчел пишет про проверку генератора. К стати- я вроде и это автору отсилал.
On MPV and Protege, generator output is controlled by PCM. If a generator no charge or overcharge condition exists, check PCM DTCs. See appropriate SELF-DIAGNOSTICS article in ENGINE PERFORMANCE.
Надеюсь переводить не надо.
И далее про проверку.
MPV 1. Connect an in-line ammeter (120-amp minimum) between generator terminal "B" connector and terminal "B" of wiring harness connector. See Fig. 2 . Turn off all electrical loads. Operate engine at 2000-2500 RPM. Turn headlights and all accessories on and verify current reading increases. 2. Measure and record generator output. See GENERATOR MAXIMUM RATED OUTPUT table. If amperage is as specified, go to next step. If amperage is not as specified, repair or replace generator. 3. Operate engine at idle. Measure voltage between terminal "B" and ground. If 13-15 volts do not exist, repair or replace generator. If 13- 15 volts do exist, generator output is okay.
Короче ничего такого, что ми не знаем.
За то в компе двывгателя возможни 3 кода про неисправность генератора.
DTC P1631: NO GENERATOR OUTPUT VOLTAGE SIGNAL Condition PCM monitors input voltage from generator and battery. DTC is set when engine is running and voltage is less than 8.5 volts for 5 seconds. Possible causes are:
 Open or short circuit.
 Missing drive belt.
 Generator malfunction.
 PCM malfunction.
Testing
1. Turn ignition on. Using scan tool, monitor ALTT V PID. Start engine. If ALTT V PID is less than 8.5 volts, go to next step. If ALTT V PID is 8.5 volts or more, problem is intermittent. See TROUBLE SHOOTING - NO CODES article.
2. Check drive belt. If belt and tension are okay, go to next step. If belt is missing or tensioner is out of limits, replace belt. After repair, go to step 9 .
3. Turn ignition off. Disconnect PCM connector. PCM is mounted to passenger floor, behind glove box. Check connector and PCM terminals. If no problems are present, go to next step. If any problems are present, repair as necessary. After repair, go to step 9 .
4. Disconnect generator connector. Check connector and generator terminals. If no problems are present, go to next step. If any problems are present, repair as necessary. After repair, go to step 9 .
5. Check continuity between generator harness connector terminal "D" (White/Red wire) and ground. If continuity is not present, go to next step. If continuity is present, repair short to ground on White/Red wire between PCM and generator. After repair, go to step 9 .
6. Check continuity between generator harness connector terminal "P" (White/Blue wire) and ground. If continuity is not present, go to next step. If continuity is present, repair short to ground on White/Blue wire between PCM and generator. After repair, go to step 9 .
7. Connect breakout box to PCM connector. Leave PCM disconnected. Check continuity between generator harness connector terminal "D" (White/Red wire) and breakout box terminal No. 53. If continuity is present, go to next step. If continuity is not present, repair open on White/Red wire between PCM and generator. After repair, go to step 9 .
8. Check continuity between generator harness connector terminal "P" (White/Blue wire) and breakout box terminal No. 30. If continuity is present, replace generator. After repair, go to next step. If continuity is not present, repair open on White/Blue wire between PCM and generator. After repair, go to next step.
9. Reconnect all components. Using scan tool, clear DTCs. Turn ignition off. Start engine. Recheck DTCs. If same DTC is present, replace PCM and go to next step. If same DTC is not present, go to next step.
10. Perform after repair procedure. See AFTER REPAIR PROCEDURE . If no DTC is present, testing is complete. If any DTC is present, go to appropriate test for diagnosis and repair.
DTC P1633: BATTERY OVERCHARGE Condition PCM monitors input voltage from generator and battery. DTC is set when engine is running and generator voltage is more than 18.5 volts or battery voltage is more than 16 volts for 5 seconds. Possible causes are:
 Short circuit.
 Generator malfunction.
 PCM malfunction.
Testing
1. Turn ignition on. Using scan tool, monitor ALTT V and B+ PIDs. Start engine. If ALTT V PID is more than 18.5 volts and B+ PID is less than 16 volts, go to next step. If ALTT V PID is 18.5 volts or less, problem is intermittent. See TROUBLE SHOOTING - NO NOTE: Check for service bulletins and on-line information. NOTE: Check for service bulletins and on-line information.

2.Disconnect generator connector. Check connector and generator terminals. If no problems are present, go to next step. If any problems are present, repair as necessary. After repair, go to step 7 .
3.Turn ignition on. Check voltage between generator harness connector terminal "D" (White/Red wire) and ground. If battery voltage
present, go to next step. If battery voltage is not present, problem is at generator. Go to step 6 .
4.Turn ignition off. Disconnect PCM connector. PCM is mounted to passenger floor, behind glove box. Check connector and PCM terminals. If no problems are present, go to next step. If any problems are present, repair as necessary. After repair, go to step 7 .
5.Turn ignition on. Check voltage between generator harness connector terminal "D" (White/Red wire) and ground. If battery voltage
not present, go to step 7 . If battery voltage is present, repair short to power on White/Red wire between PCM and generator. After repair, go to step 7 .
6.Check voltage between generator terminal "D" and ground. If battery voltage is not present, go to next step. If battery voltage is present, replace generator. After repair, go to next step.
7.Reconnect all components. Turn ignition off, then on. Recheck DTCs. If same DTC is present, replace PCM and go to next step. If
DTC is not present, go to next step.
8.Perform after repair procedure. See AFTER REPAIR PROCEDURE . If no DTC is present, testing is complete. If any DTC is present, go to appropriate test for diagnosis and repair.
DTC P1634: GENERATOR TERMINAL B CIRCUIT OPEN

AFTER REPAIR PROCEDURE
Connect scan tool. Turn ignition off. Turn ignition on. Check for DTCs. Select CLEAR. Select TRIGGER. Select CANCEL. Turn ignition off.
Печально! Но кажется, что без помощи сканера воевать с этим генератором трудно. Из за того, что его после ремонта нельзя запустить, не убрав коди ошибок.

Автору чего?

Да вроде того , и разжевано всё как для полных чайников.

Ничего, шестёрочное РР рулит А лампочку из приборки можно и выкрутить , чтоб глаза не мозолила. Щютка.

ELK, спасибо за подробную информацию

Рулит конечно не только реле от шестёрки. Да и лампочку можно не выкручивать, а даже с другой запаралелить. Но вот такое решение более похоже на предпродажную подготовку, применяемую автоторговцами. Тем более остаётся вопрос- каким образом ЭБУ отреагирует на такое издевательство.

Возможен... Кажется, на 124-х мерсах на щитке приборов взади стоит предохранитель, защищающий цепи подсветки приборов, клавиш, и т. п. Причём выполнен очень оригинально - как патрончик лампочки щитка, а в нем текстолитовая пластинка с дорожкой. Патрончик этот легко узнать - обычно он красного цвета.

кстати Господа для информации , недавно ставил сигналку на мазду 3 которые новые пошли красивые такие.
блок предохранителей обыскался, пока ни разобрал пол торпеды и уж отчаявшись решил снять бардачёк а они за бардачком находятся ....
к стати там уже эта как её КАН шина, намучился труба, больше не возьмусь....

Вот именно для таких машин и разработани специальние КАН сигналки. Ставить одно удовольствие. Тем более, что солидние фирми ещо и схему подключения к конкретному автомобилю предостовляют.

Существует мнение, что вот защитные свойства у них слабоваты: стандартный блочёк, стандартная установка, стандартный обход этого дивайса как следствие... Не говоря уже про скудноватый функционал (в смысле разных потребительских "наворотов").

Зы. Мнение большей частью не моё, но компетентных людей из конфы на авто.ру "Защита от угона"

я вот думаю что все эти ноу хау придумывают для того чтоб показать что мы не зря сидим и хлеб едим.
примеру автоэлектрика автомобилей последних моделей ВАЗ, газ и прочеенаши марки.
электрооборудование мерседесов это вообще ... нет слов.
об этом писал уже но напомню имм мерина идет целый жгут на него (проводов 15) и все этого для того чтоб заблокировать стартер.
просто КБ мерседеса показало что работает иначе его расформировали бы. также и все остальные кб не только автоэлектроники.
