Conjunto de lógica elétrica FAW para cabine do motorista: Uma desconstrução abrangente de 70 Componentes principais

Bem-vindo a este guia técnico abrangente sobre o Conjunto de lógica elétrica FAW para cabine do motorista (Conjunto 577). Este é o completo “central nervous system” of the cab for the FAW Jiefang CA4251P66K24T1A3E5 6×4 trator semirreboque diesel. This is not just a set of wires; it is the integrated network that handles all driver inputs, data processing, and power distribution.

O Conjunto de lógica elétrica FAW para cabine do motorista é a “lógica” system that connects every single switch, sensor, luz, 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’ (3722010-92C).

Este guia detalhado é um recurso essencial para técnicos profissionais e especialistas em peças. Vamos desconstruir todo Conjunto de lógica elétrica FAW para cabine do motorista em seu 70 componentes reparáveis, including the main ‘Vehicle control unit’ (3738010-91T-C00), the various modular wiring harnesses, and all the driver-facing switches and controls.

Essencial “Lógica”: The Control Units (ECU/BCM)

O “cérebro” do Conjunto de lógica elétrica FAW para cabine do motorista is its set of computers. The ‘Vehicle control unit assembly’ (3738010-91T-C00), often called the Body Control Module (BCM), is the central processor.

Instead of a simple “one switch, one light” circuito, o “lógica” is multiplexed. The ‘Turn signal switch’ (3735110-61B), por exemplo, doesn’t directly power the lights. It sends a low-voltage “request” to this BCM. The BCM then “logicamente” decides to activate the turn signals, the ‘Side turn signal lamp’ (3726030A109), and the dashboard indicator.

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

O “Nervous System”: Modular Wiring Harnesses

O Conjunto de lógica elétrica FAW para cabine do motorista is not one giant, impossible-to-service “spider web” of wires. Isso é “lógica” is modular. The system is built from several key sub-harnesses:

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

Este modular “lógica” é uma parte fundamental do Conjunto de lógica elétrica FAW para cabine do motorista. 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.

A interface do motorista: Switches and Controls

This assembly includes all the tactile “entradas” the driver uses to command the Conjunto de lógica elétrica FAW para cabine do motorista. These are the components the driver touches every day.

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

Door and window controls are also part of this assembly. This includes the ‘Power window switch’ (3746020-A01), its ‘Cover plate’ (3746011-A01), and the ‘Power mirror switch’ (3782010-A01) with its cover. These switches send “lógica” signals to the BCM, which then activates the motors.

Other critical inputs include the ‘Start switch assy’ (3704010-A01), ‘Stop light switch assy’ (3720010-A01), and the ‘Hazardous goods indicator light assy’ (3713010-1502). Each switch is a “lógica” input to the Conjunto de lógica elétrica FAW para cabine do motorista.

Poder & Segurança: Fuse Boxes and Auxiliary Power

Uma chave “lógica” do Conjunto de lógica elétrica FAW para cabine do motorista is safe power distribution. This is handled by the ‘Fuse box assy’ (3722010-92C) and the ‘Insurance plug assy-accessory’ (3722020B91W).

The fuse box is the “lógica” 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-A01). 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-A01) 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 Conjunto de lógica elétrica FAW para cabine do motorista.

Auxiliary Systems: Audio, Antennas, and Comfort

O Conjunto de lógica elétrica FAW para cabine do motorista also controls all comfort and communication systems. The ‘Left/Right full-range speaker assy’ (7901015-A01, 7901025-A02) 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’ (7903010-61B), ‘Conjunto de antena GPS/BD’ (7903060-61B), and ‘4G antenna assy’ (7903060-95T). Esse “lógica” of using multiple, specialized antennas ensures the strongest possible signal for AM/FM radio, GPS navigation, and 4G-based telematics (like the ‘Tachograph’ 7914010-61B). *

Even simple warning devices like the ‘Alarm for vehicle traveling’ (3818060-A01) (a “reverter” ou “aviso” beeper) are tied into this comprehensive Conjunto de lógica elétrica FAW para cabine do motorista.
