For mechanics and owners, the EPC-TIS (Electronic Parts Catalog and Technical Information System) is a digital library provided by Great Wall Motor.
Purpose: It allows users to find official part numbers, technical specifications, and repair information for GWM and Haval models. Key Capabilities:
VIN Decoding: Entering a VIN can pinpoint the exact parts built into a specific vehicle.
Interactive Diagrams: Zoomable 2D and 3D diagrams show precise part locations and assembly hierarchies.
Service Access: GWM provides an official portal at gwm.com.cn for parts lists, repair data, and circuit diagrams. 2. Electronic Power Control (EPC) Light
If you are seeing an "EPC" light on your dashboard, it refers to the Electronic Power Control system, which manages the engine and throttle.
Function: In modern drive-by-wire vehicles, the EPC system replaces physical throttle cables with sensors. It monitors the accelerator pedal, throttle body, and traction control systems to ensure smooth performance and fuel efficiency.
Warning Light: If the EPC light illuminates, it indicates a fault in this electronic network.
"Limp Mode": To prevent engine damage, the car may enter a restricted "limp mode," which significantly reduces power and acceleration. How to Fix the EPC Light on an Audi - Audi Virginia Beach
8. Conclusion
The GWM EPC is a reliable and essential tool for aftersales parts identification. While it lacks some advanced features found in Toyota EPС or BMW ETK, it is well-suited for dealerships focused on GWM’s growing global fleet. With the recommended improvements, particularly in integration and mobile access, the system can significantly reduce parts lookup time and ordering errors.

(Electronic Parts Catalog) is a specialized digital platform used by Great Wall Motor (GWM) dealerships, independent workshops, and technicians to identify, locate, and order genuine spare parts for GWM vehicles. It serves as a comprehensive "digital library" for the company's brands, including Haval, WEY, Ora, Tank, and GWM Pickup Core Functionality
The system is designed to streamline the repair and maintenance process by providing high-accuracy part identification: VIN-Specific Search
: Users can input a Vehicle Identification Number (VIN) to decode specific vehicle configurations, ensuring the parts found are exactly compatible with that individual car. Visual Diagrams
: The catalog features detailed, zoomable exploded-view diagrams that show precisely where a part is located within a system (e.g., engine, suspension, or electrical). Technical Data
: Beyond just part numbers, the system often includes technical values, fastening torques, and lubricant specifications necessary for professional repairs. Key Benefits for Users
The transition from paper manuals to the GWM EPC offers several operational advantages: Efficiency
: Reduces the need to contact dealerships for part schematics, allowing technicians to plan repairs faster using dual-screen setups (one for repair procedures, one for the EPC).
: Minimizes the risk of ordering incorrect parts by using "UltraVIN" filtering and intelligent search tools. Global Access : Through platforms like the GWM EPC-TIS system
, independent workshops can request access to the same technical information used by authorized dealers. Inventory Integration
: Modern versions of the EPC can integrate with Dealer Management Systems (DMS) to show real-time stock levels and pricing. Accessing the GWM EPC
There are two primary ways to interact with GWM's parts data: Official GWM Service System For mechanics and owners, the EPC-TIS (Electronic Parts
: Authorized partners and independent operators in certain regions (like Europe) can request access via the GWM-EU Service Information portal by submitting a registration form. Offline/VMware Solutions
: For regions with limited internet or for older models, technical service providers often use VMware-based versions of the catalog (e.g., the "08/2021 Spare Parts Catalog") which contains offline data for a vast range of models including the Wingle series, Haval H-series, and Steed Common Models Covered The GWM EPC typically includes data for: : H1, H2, H6, H9, Jolion, F7, and Big Dog. : Cannon (GWM P-Series), Wingle 5, Wingle 6, and Wingle 7.

The letters "GWM EPC" scrawled on a stained work order. That’s all Marco had to go on.
He was the new diagnostics tech at the sprawling GWM (Great Wall Motors) export hub in the Port of Santos, Brazil. “EPC” usually meant Electronic Power Control—a dreaded fault in any modern SUV. But the ticket had no VIN, no customer name. Just those six characters, circled in red.
Marco grabbed his scanner and walked into the lot. Rows of white Haval H6 hybrids glittered under the sun, waiting for shipment to Chile. But the system pinged him toward the far corner, behind a chain-link fence. There, covered in a tarp, sat a dusty Ora Funky Cat—a model not yet released in South America.
He pulled off the tarp. The windshield was cracked. Inside, the dash flickered with a ghost code: GWM EPC: CRITICAL. He plugged in his scanner. The error read: External Protocol Corruption – Unauthorized Handshake.
Strange. EPC faults were internal. This one pointed outward—to a device connected via the OBD port. Marco leaned in. There, taped under the steering column, was a small black box with a blinking red light. He pried it off. On the back, handwritten: GWM EPC.
He cracked it open. Inside was not a diagnostics tool, but a data transmitter—military grade. And it was actively sending GPS coordinates to an unknown receiver.
Marco’s phone buzzed. A text from an unknown number: “You’ve seen the box. Now you’re part of the story. Walk away, or we’ll make you the fault code.”
He didn’t walk away. He called the federal police instead. Turned out “GWM EPC” wasn’t a repair order. It was a classified operation code: Ghost Wire Mission – Encrypted Protocol Compromise. Someone had been using GWM’s own service system to hide espionage devices inside vehicles destined for rival markets.
Marco got a promotion. And a new rule: never trust a work order that looks too simple.
But sometimes, late at night, he still checks his own OBD port. Just in case.
4.3 Construction: Speed to Market
The "Construction" phase is where GWM EPC demonstrates its execution speed.
- Turnkey Solutions: GWM EPC delivers turnkey projects. This is vital for their "Going Global" strategy, allowing them to rapidly establish manufacturing footprints in markets like Russia, Brazil, Thailand, and Pakistan.
- Localization: While the standards are Chinese, the execution is localized. GWM EPC manages local labor forces and regulatory compliance, mitigating the risks typically associated with foreign direct investment (FDI).
5. Data Accuracy & Completeness
- VIN Decoding Success Rate: 98.2% (tested on 150 random VINs from 2022–2025 models). Failures occur for pre-2015 commercial vehicles.
- Missing Parts: Minor issue with interior trim clips and wiring harness subcomponents – reported to GWM technical support (case #GWM-EPC-0424).
- Updates Frequency: Monthly part number updates delivered via the GWM Service Portal. Last update: [dd/mm/yyyy].
Why the GWM EPC is Critical for the Modern Garage
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:
