Блок электрической логики FAW для кабины водителя: Комплексная деконструкция 70 Основные компоненты

Добро пожаловать в это подробное техническое руководство по Блок электрической логики FAW для кабины водителя (Сборка 577). Это полный “central nervous system” of the cab for the FAW Jiefang CA4251P66K24T1A3E5 6×4 дизельный полуприцеп тягач. This is not just a set of wires; it is the integrated network that handles all driver inputs, data processing, and power distribution.

The Блок электрической логики FAW для кабины водителя является а “логика” system that connects every single switch, датчик, свет, and computer. Its function is to take driver commands (from the ‘Combination switch’ or ‘Power window switch’) and route them to the correct component, all while drawing power safely from the ‘Fuse box assy’ (3722010-92Вт).

Это подробное руководство является важным ресурсом для профессиональных технических специалистов и специалистов по запчастям.. Мы разберем всю Блок электрической логики FAW для кабины водителя в свой 70 исправные компоненты, including the main ‘Vehicle control unit’ (3738010-91T-C00), the various modular wiring harnesses, and all the driver-facing switches and controls.

Основной “Логика”: The Control Units (ECU/BCM)

The “мозг” принадлежащий Блок электрической логики FAW для кабины водителя is its set of computers. The ‘Vehicle control unit assembly’ (3738010-91T-C00), often called the Body Control Module (БЦМ), is the central processor.

Instead of a simple “one switch, one light” схема, а “логика” is multiplexed. The ‘Turn signal switch’ (3735110-61Б), например, doesn’t directly power the lights. It sends a low-voltage “request” to this BCM. Тогда БЦМ “логически” decides to activate the turn signals, the ‘Side turn signal lamp’ (3726030А109), and the dashboard indicator.

This system is mounted on the ‘Controller bracket (ABS+BCM)’ (3724665-92Вт), which shows it is co-located with the ABS computer for efficient data sharing. This ‘Tachograph’ (7914010-61Б) and ‘On-board information service terminal’ (7913010A54W-C00) are also “логика” units that record vehicle data.

The “Нервная система”: Modular Wiring Harnesses

The Блок электрической логики FAW для кабины водителя is not one giant, impossible-to-service “spider web” of wires. Его “логика” is modular. The system is built from several key sub-harnesses:

• ‘Dashboard wire harness assy’ (3724010-81р, 3724010A97R, и т. д.)
• ‘Left cab wire harness assy’ (3724020ND04, 3724025ED04, и т. д.)
• ‘Door wire harness assy’ (3724030-D04, 3724035-D04)
• ‘Functional switch wire harness assy’ (3724080-97р)
• ‘Roof wire harness assy’ (3724050-91Вт, 3724105-88р)

Этот модульный “логика” is a key part of the Блок электрической логики FAW для кабины водителя. If a door is damaged in an accident, a technician only needs to replace the ‘Door wire harness assy’, not the entire cab’s wiring. This dramatically reduces repair time and cost.

The Driver Interface: Switches and Controls

This assembly includes all the tactile “inputs” the driver uses to command the Блок электрической логики FAW для кабины водителя. These are the components the driver touches every day.

Primary driving controls are grouped on the steering column, including the ‘Turn signal switch’ (3735110-61Б) and the ‘Wiper switch’ (3735120-61Б).

Door and window controls are also part of this assembly. This includes the ‘Power window switch’ (3746020-А01), its ‘Cover plate’ (3746011-А01), and the ‘Power mirror switch’ (3782010-А01) with its cover. These switches send “логика” signals to the BCM, which then activates the motors.

Other critical inputs include the ‘Start switch assy’ (3704010-А01), ‘Stop light switch assy’ (3720010-А01), and the ‘Hazardous goods indicator light assy’ (3713010-1502). Each switch is a “логика” input to the Блок электрической логики FAW для кабины водителя.

Власть & Безопасность: Fuse Boxes and Auxiliary Power

Ключ “логика” принадлежащий Блок электрической логики FAW для кабины водителя is safe power distribution. This is handled by the ‘Fuse box assy’ (3722010-92Вт) and the ‘Insurance plug assy-accessory’ (3722020B91W).

The fuse box is the “логика” hub for safety. It takes the main 24V power from the battery and distributes it to every single circuit, from the ‘Interior lighting lamp’ (3714030-91W-C00) to the ‘Cigarette lighter’ (3725020-А01). Each circuit is protected by a fuse. If a wire shorts to ground, the fuse is a “sacrificial link” that blows instantly, breaking the circuit and preventing a fire.

This assembly also includes driver-facing power ports, such as the ‘Cigarette lighter head assy’ (3725020-А01) and the ’24V power socket assy’ (3736050-B28). These ports are also protected by the fuse system, ensuring that a faulty phone charger cannot damage the entire Блок электрической логики FAW для кабины водителя.

Auxiliary Systems: Audio, Antennas, and Comfort

The Блок электрической логики FAW для кабины водителя also controls all comfort and communication systems. The ‘Left/Right full-range speaker assy’ (7901015-А01, 7901025-А02) provide the audio output for the truck’s radio and communication systems.

This system is fed by multiple inputs, managed by the ‘Multi-function antenna assy’ (7903010-61Б), ‘GPS/BD antenna assy’ (7903060-61Б), and ‘4G antenna assy’ (7903060-95Т). Этот “логика” of using multiple, specialized antennas ensures the strongest possible signal for AM/FM radio, GPS navigation, and 4G-based telematics (like the ‘Tachograph’ 7914010-61Б). *

Even simple warning devices like the ‘Alarm for vehicle traveling’ (3818060-А01) (а “обеспечить регресс” или “warning” beeper) are tied into this comprehensive Блок электрической логики FAW для кабины водителя.
