WG9716582301
FAW
| Parameter | Specification |
|---|---|
| Part Number | WG9716582301 |
| Product Name | Central Body Control Unit (CBCU) / Electrical Junction Box Assembly |
| Nominal Voltage | 24V DC (Operating Range: 18V – 32V) |
| Housing Material | High-strength, flame-retardant engineering plastic (UL94 V-0 rated) |
| Internal Construction | Multi-layer PCB with surface-mount components, integrated relays, and fuse terminals |
| Connectors | Multiple color-coded multi-pin automotive-grade plugs (e.g., gray, black, white) for fool-proof mating |
| Integrated Relays | Varies by suffix (see Cross Reference); typically 20A, 40A, or 70A configurations |
| Fuse Type | Blade-type (ATO/ATC) fuse slots for circuit protection |
| Weight | Approx. 1.5 – 2.5 kg (unit only); ~8.0 kg with packaging |
| IP Rating | IP54 (dust-protected & splash-resistant when properly sealed) |
| Compliance | Designed per QC/T automotive electrical standards; compatible with China VI emission-compliant trucks |
Exact Part Number Matching Is Mandatory
Erratic lighting behavior
Failure to start (due to incorrect ignition relay logic)
CAN bus communication errors
Permanent damage to sensors or ECU
Always confirm the full part number including suffix (e.g., +011).
Mismatched units may cause:
Water & Moisture Protection
Typically mounted under the passenger-side dashboard in a sealed electrical box.
Never allow water spray during interior cleaning.
After deep-water fording, inspect seals and dry the compartment thoroughly.
Moisture ingress is the #1 cause of PCB corrosion and total module failure.
Power-Down Before Service
Always disconnect the battery negative terminal AND turn off the main power switch before unplugging connectors or replacing the unit.
Hot-plugging can generate voltage spikes that destroy sensitive microcontrollers.
Fuse Replacement Protocol
Replace blown fuses only with identical amperage rating (e.g., 15A, 20A).
Never use copper wire, foil, or oversized fuses—this bypasses protection and risks fire or PCB burnout.
Diagnose Before Replacing
Internal relay failure
Power supply issue to CBCU
Damaged CAN communication line
If multiple systems fail simultaneously (e.g., all lights + wipers), but individual fuses are intact, suspect:
Use a SINOTRUK-compatible diagnostic tool (e.g., Sinotruk TechTool) to read DTCs before condemning the module.
