SHACMAN X3000 Voith Retarder Cabin Control Wiring Harness Nano System 712-25456-0033
As a key component for "wear-free" auxiliary braking in heavy-duty trucks, the Voith hydrodynamic retarder ensures exceptional safety when descending long, steep gradients under heavy loads. The wiring harness serves as the "central nervous system," facilitating the transmission of high-speed electrical signals and CAN bus data between the retarder's "brain"-the Electronic Control Unit (ECU)-and the vehicle's Nano central control module in the cab, as well as the gear-shift lever (manual control switch).
Voith Retarder (Nano System) Cabin Control Circuit Maintenance BOM
| BOM Level | Part Number (P/N) | Description (EN) | Qty / Vehicle | Key Technical Specifications / Remarks |
|---|---|---|---|---|
| 1.0 | 712-25456-0033 | Voith Retarder Cabin Control Wiring Harness | 1 Pc | Core Item: Dedicated Nano system version. Features a built-in high-precision CAN-Bus twisted pair with a 120Ω characteristic impedance and multi-stage flame-retardant corrugated protective sleeving. |
| 1.1 | DZ96189584300 (or per Shaanxi Auto spec) |
Retarder Master Multi-Function Switch Lever | 1 Pc | High-frequency companion item: Located below the right side of the steering wheel (includes 1st-5th stage potentiometer lever and cruise control button). Internal potentiometers wear out over time; signals are routed via the 1.0 harness. |
| 1.2 | DZ97189585320 | Cab Firewall Connector Pass-Through Socket | 1 Set | Critical Routing Component: The sealed transition junction separating the clean cab interior from the muddy chassis area. If water or mud enters here, the CAN-Bus network will fail. |
| 1.3 | Per Voith standard | Voith Retarder Control Unit (ECU) | 1 Pc | The core computer board of the retarder system. The terminal plug of the 1.0 harness connects directly here to convert shift lever signals into duty-cycle actuation currents. |
| 1.4 | Automotive Standard | Automotive Mini Fuse (5A - Nano Dedicated) | 2 Pcs | Located inside the cabin's main Nano power distribution box. Functions as a sacrificial overcurrent protection item in case of wire chafing or shorts. |
| 1.5 | Industrial Grade | Dual-Wall Heat-Shrink Tubing (with Internal Glue) | 1 Set | Consumable. Used for structural sealing, waterproofing, and insulation when doing manual splices or localized repairs on chafed harness sections. |
| 1.6 | PA66 Flame-Retardant | Heavy-Duty Cabin Cable Ties | 1 Set | Essential consumable. Used to securely anchor the new harness to the dashboard skeleton and interior brackets, preventing friction against moving parts. |
