Great Wall Motors is actively migrating its parts catalog to a unified cloud platform called GWRI (Great Wall Ready Integration) . This new system will integrate the EPC with the EWM (Electronic Workshop Manual) and ETM (Electrical Troubleshooting Manual) .
Future updates likely include:
Working on a Haval Jolion or a GWM Cannon? You cannot rely on visual matching alone. Modern GWM vehicles integrate complex electronics, multi-platform architectures (e.g., the L.E.M.O.N. platform), and region-specific variations (Middle East, Australia, South Africa, Russia).
Here is why the EPC is non-negotiable:
Even experienced mechanics make mistakes. Avoid these:
Pitfall #1: Ignoring the "Variant" Filter GWM often releases "Facelift" models without changing the main model code. The EPC will list multiple variants (e.g., B06, B06FL). Always check your vehicle’s production month.
Pitfall #2: Confusing LHD vs. RHD Left-hand drive and right-hand drive parts (steering racks, dashboard wiring, headlights) have wildly different part numbers. The GWM EPC defaults to LHD; you must manually toggle the "Steering Position" filter.
Pitfall #3: Assuming EVs use the same catalog The Ora and Wey brands have a separate module within the EPC. If you search for a battery cell for an Ora R1 using the Haval menu, you will find nothing.
| Symptom | Most Likely Cause | Affected Models | |---------|------------------|------------------| | EPC light ON, rough idle, reduced power | Carbon buildup on throttle plate or faulty throttle position sensor | Haval H6 (1.5T GW4G15), Jolion | | EPC + Engine light, no acceleration | Brake pedal switch stuck/short circuit (two signals conflict) | GWM Cannon Ute, Poer | | EPC light flashes, EPB auto-engage | Low system voltage (<11V) or CAN bus interference | Ora Good Cat, Haval F7 | | Light ON, no start (push-button) | Clutch position sensor (manual) or brake switch (auto) not detected | GWM Steed, Wingle |
The GWM EPC (Electronic Parts Catalog) is a digital system used to identify, locate, and order genuine spare parts for Great Wall Motor vehicles. It serves as a comprehensive "digital library" for the company's brands, including Haval, Wey, Ora, Tank, and GWM Pickup. 🛠️ Accessing the EPC System
GWM provides different access points depending on your region and role (dealer vs. independent workshop).
EPC-TIS System (Europe): GWM Europe offers a combined Electronic Parts Catalog and Technical Information System (EPC-TIS).
Purpose: Allows independent workshops and individuals to find parts and technical data for repairs.
Access: Requires downloading an access form and sending it to service@gwm-eu.com.
Cost: Subscriptions are available by week (€30), month (€60), or year (€480).
Official Global Service Portal: The central GWM Service System provides access to manuals, maintenance data, and parts information.
Third-Party Catalogues: For older models or offline use, vendors like Epcatalogs sell VM Ware versions of the spare parts catalog (e.g., the 08/2021 update for ~$150 USD). 📦 What the Catalog Covers
The EPC contains detailed technical documentation for nearly all GWM vehicle components:
Model Coverage: Includes the Haval series (H3, H5, Jolion, H6), GWM Pickup/Cannon (Poer/P-Series), and New Energy Vehicles (NEVs) under the Ora and Tank brands. Component Data:
Exploded Diagrams: Zoomable 2D/3D visuals that show exactly where a part is located on the vehicle.
Part Numbers: Specific codes (e.g., ZEZF068923 for diagnostic tools) to ensure ordering accuracy.
Core Systems: Covers engine, transmission, brake assemblies, water pumps, and timing belts.
Integration with TIS: Often linked with service manuals, circuit diagrams, and labor time guides to assist in professional servicing. 💡 Purchasing Genuine Parts
While the EPC helps you find the correct part number, purchasing is typically done through authorized channels: GWM Service System
