Developer Access & Codes

How to reach the hidden Developer / Engineer menu on the Chery / Jetour head unit, plus the useful secret codes. For your own vehicle — engineer mode changes low-level settings, so read the warnings.

Open the developer / engineer menu

*#20240730#
dial this in the head unit's Phone / Dialer app
  1. Open the Phone (Dialer) app on the head unit.
  2. Type *#20240730# on the keypad. No SIM or call is needed — the code fires a hidden SECRET_CODE broadcast.
  3. The AutoLink Engineer Mode (com.autolink.engineermode) launches automatically as you finish typing the last #.
  4. If it asks for a password, see Passwords below.

Passwords

If Engineer Mode prompts for a password
AutoLink's EngineerMode gates some pages behind a factory password (its code path decodes a Factory password and checks Pwd). It is model/region/date-specific and not fixed in the app itself — try your dealer/vendor factory password. Common defaults to try on AutoLink units: 00000000, the current date YYYYMMDD, or a supplier code.

For the 加密设置 · Encrypted Settings gate specifically, the password is computed live below.

How it's computed
The 6-digit code is derived from the date's month (M), day (D) and hour (H) against a fixed SOP seed of 20250530:( 20250530 × (M×10000 + D×100 + H) − H ) mod 1000000zero-padded to 6 digits. Only the hour changes it within a day, so it rotates every hour on your car's clock.

Inside Engineer Mode, 加密设置 → 进入加密设置 (Enter Encrypted Settings) asks for a 6-digit password derived from the car's month, day & hour. It rotates every hour — this updates automatically. Match it to your car's clock.

Clock must match
Only the hour matters — the password is the same from XX:00 to XX:59. If your car's clock differs from this device, read the car's time and pick that hour's row in the schedule, or fix the car clock in Settings → Date & Time.
