Use a scanner compatible with GWM (e.g., X431, Launch, or GWM diagnostic tool). Common codes:
| DTC | Description | Fix | |-----|-------------|-----| | P2138 | APP sensor correlation error | Replace pedal assembly | | P0122 | Throttle position sensor circuit low | Clean or replace throttle body | | P0571 | Brake switch circuit malfunction | Adjust or replace switch | | U0100 | Lost communication with ECM/TCU | Check CAN wiring, ground points |
Crucially, the GWM EPC respects "Region Lock." A part for a Haval H6 sold in China (CHN-DM) will often have a different connector or mounting point than a Haval H6 sold in Australia (AUS). The EPC forces you to select the correct region before displaying data.
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.
Appendices (optional):
The GWM EPC system is robust but sensitive to voltage fluctuations, switch wear, and throttle contamination. Most repairs involve cleaning the throttle body, replacing brake pedal switches, or addressing low battery voltage. For persistent faults, a dealer-level scan is required to access GWM-specific PID data.

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 gwm epc
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
