⚠ Danger High voltage

This car's traction battery runs at several hundred volts. Anything marked high-voltage (orange cables, battery pack, electric drive, charger, A/C compressor, PTC heater) can kill. Only work on those parts if you are trained, have insulated tools and gloves, and have followed the power-down procedure in the manual. The 12 V system, body, brakes, suspension and interior are ordinary workshop jobs.

02 How to use

  1. Best on a computer. With thousands of pages, finding the right one is much easier on a big screen, where the contents, search results and diagrams sit side by side. The phone version works too (contents behind ☰) and is handy once you know the page: every page has its own link, so you can send a page you found on the computer to your phone.
  2. Search (top bar, or press /) for a fault code (P16E291, U019887), a part (front bumper, wiper motor) or a symptom (not charging, noise). Results match page titles first, then the full text.
  3. Contents on the left follows the original manual's structure. Underlined links inside a page jump to the referenced page.
  4. Prev / Next (or ← →) steps through pages in manual order. Click any diagram to enlarge it.
Notice Which car these manuals describe
  • Repair manual and circuit diagrams: China market, left-hand drive. On a right-hand-drive car, driver side (主驾) is the right and passenger side (副驾) the left; parts around the dashboard, steering column, pedals and wipers may be mirrored. China-only equipment is tagged or noted, and export part numbers can differ: check with the dealer before ordering. Procedures, torque values, fluids and fault codes are generally the same.
  • Circuit diagrams come in two editions, 2024 model and 2025 refresh. Pages that differ have a switch; the export cars we have seen look closest to the 2024 wiring, so pages open on 2024. How to check your own car: see Fuses. Show:
  • Owner's manual: GAC's own English, July 2025 edition. Where the older September 2024 right-hand-drive edition differs in a way that matters, a note on that page quotes it. Download the 2025 edition PDF, 28 MB · the 2024 RHD edition PDF, 9 MB
Note Machine translation

The repair manual and circuit diagrams are machine translated from Chinese, so some sentences read awkwardly; numbers, part numbers and fault codes are unchanged. Switch to EN + 中文 at the top to see the original under each line.

Use with your AI Claude, ChatGPT and others

An AI assistant can read this whole manual for you: search it, look up fault codes, walk you through a check step by step, find the right fuse and read the circuit diagrams. Add this address to it as a connector (no sign-in needed):

https://www.aionv.app/mcp

  • Claude (app or claude.ai): Settings → Connectors → Add custom connector, then paste the address.
  • ChatGPT: add it as a connector in developer mode.
  • Other tools (Claude Code, Cursor…): add it as a remote MCP server.

Then ask, for example, “My Aion V shows fault P16E291. What should I check?” The AI can still get things wrong: check its answer on the page it links to, and leave high-voltage work to trained people.

About This site

Made by an Aion V owner and shared free with other owners and workshops. Not affiliated with GAC, its dealers or distributors. The repair manual and circuit diagrams are GAC's Chinese manuals, machine translated; the owner's manual is GAC's own English; Essentials and OBD data are our own work.

Is there an English repair manual for the GAC Aion V?
GAC publishes the repair manual and wiring diagrams in Chinese. This site has both in English, with the Chinese original under every line, plus GAC's official English owner's manual.
Does it fit my car?
It covers the 2nd-generation Aion V, 2024 onward. The source manuals are for China-market left-hand-drive cars: see the notice above for right-hand-drive cars and the two wiring editions.
Can I use it without signal?
Yes. Save the whole manual once (about 230 MB) and it works offline on a phone or a computer.
Is it safe to work on the car myself?
Most of the car is ordinary workshop work. The high-voltage parts are not: leave those to trained people (see the danger label above).
