BYD Shark 6 OTA Updates: How to Keep Your Software Always Current?
The BYD Shark 6 supports over-the-air (OTA) software updates through its infotainment system. Check, schedule, or trigger an update via infotainment touchscreen → System → Version → Vehicle Version → Upgrade. The vehicle must be parked in Park (P), have sufficient battery charge, and a stable mobile or Wi-Fi connection. During an update only the smart key, interior light, hazard lights, and window switches remain active. All procedures come directly from the BYD Shark 6 Owner's Manual.
OTA Updates at a Glance
| Specification | Detail |
|---|---|
| Update method | Over-the-air via mobile network or Wi-Fi |
| Access path | Infotainment → System → Version → Vehicle Version → Upgrade |
| Vehicle state required | Parked in P, safe area, sufficient battery |
| Functions available during update | Smart key, interior light, hazard lights, window switches only |
| Three install options | Update immediately, schedule, or trigger via mobile phone (if supported) |
| Failure recovery | Retry; if it fails again, contact a BYD authorised dealer |
| Measurement note | The vehicle cannot be charged or discharged while an OTA update is in progress. |
What Is OTA and Why It Matters for PHEVs?
Over-the-air (OTA) is the process of installing new software on your vehicle wirelessly, without a workshop visit. The Shark 6 receives updates from BYD's servers through embedded mobile communication or a Wi-Fi connection.
For a PHEV like the Shark 6, OTA matters more than for a pure ICE vehicle. The Shark 6 carries a high-voltage battery, an engine, multiple ADAS sensors, and a sophisticated infotainment platform — each with firmware BYD continues to refine after the vehicle is sold.
OTA updates are also a pillar of automotive cybersecurity. The international framework is UNECE Regulation No. 155, which sets safety standards for vehicle software updates.
What Gets Updated: Infotainment, ADAS, Battery BMS, Engine Mapping?
The Shark 6 OTA system can refresh multiple control modules across the vehicle. Common update categories include:
- Infotainment system: Touchscreen UI, navigation maps, voice assistant (BYD Assistant), media features
- ADAS: Adaptive Cruise Control, ELKA, BSD, AEB calibration and behaviour
- Battery management system (BMS): Charging algorithms, thermal protection thresholds
- Engine control unit: Fuel economy mapping, emissions tuning
- Driving modes: Refinements to EV, HEV, ECO, Normal, Sport behaviour
- Vehicle gateway and security: Cybersecurity patches
If you have noticed changes to how your Shark 6 driving modes respond after a major update, that is the OTA system at work.
How to Check for Available Updates on the Shark 6?
The path is fixed across every software version:
- Park the vehicle safely with the gear in P
- Power the infotainment system on
- Tap System on the touchscreen
- Open Version
- Select Vehicle Version
- Tap Upgrade to check for available updates
When an update is available, the system shows a prompt with three choices: upgrade immediately, schedule the upgrade for a later time, or trigger it through a paired mobile phone (if supported in your region).
Update via Wi-Fi vs Mobile Data: Which Is Better?
Both options are supported. The owner's manual specifies that the mobile communication network connection must be normal for an OTA upgrade to succeed.
| Connection | Pros | Cons |
|---|---|---|
| Wi-Fi (home) | Faster, no data charge, more stable for large packages | Requires Wi-Fi signal to reach where the Shark 6 is parked |
| Mobile data (embedded) | Always available where mobile coverage exists | May be slower for large updates; coverage varies |
| Measurement note | For major BMS or engine ECU updates that can be several hundred MB, Wi-Fi is the better default. Use mobile data for smaller infotainment or ADAS patches. | |
How Long Do Updates Take? (Do Not Drive During Updates)?
Update time varies by package size. Small infotainment patches may complete in 10 to 20 minutes. Larger BMS, engine, or ADAS module updates can take 30 to 60 minutes or more.
The manual is explicit on what you cannot do during an update:
- Do not move the vehicle
- Vehicle cannot be charged or discharged during the process
- Most vehicle functions are unavailable
- Only the smart key (lock/unlock), interior light, hazard lights, and window switches remain operational
Before starting, ensure the vehicle has sufficient battery and avoid installing third-party OBD-port devices. For more on protecting the high-voltage battery, see our Shark 6 battery temperature guide, and for pre-update charging best practice, our complete charging guide.
What to Do If an Update Fails or Freezes?
OTA failures are uncommon but happen. The manual provides a clear recovery path:
- Try the update again. Most failures recover cleanly on retry.
- Check connection quality. Wait until you have stable Wi-Fi or strong mobile signal.
- Confirm vehicle state. Gear in P and battery has adequate charge.
- Contact a BYD authorised dealer. If the update fails a second time, the manual recommends professional handling.
After a failed update, watch the instrument cluster for unusual warning lights. Our Shark 6 dashboard warning lights reference covers what each symbol means.
Update History: How to Check Installed Version
To confirm which software version your Shark 6 is running:
- Tap System on the infotainment touchscreen
- Open Version
- Select Vehicle Version
The screen displays each major module's current version. Note your version before any major update so you can confirm the change afterwards. If you raise a service ticket with BYD, the version number is usually requested first.
For official software support, refer to your local BYD service network via the BYD global site or your regional dealer.
Opting Out of Automatic Updates
The Shark 6 does not force-install updates without your acknowledgement. When a new package is available, the prompt gives you three choices: upgrade immediately, schedule for a chosen time, or upgrade through a paired mobile phone where supported.
To delay an update, scheduling for an overnight slot with the vehicle parked at home on Wi-Fi is usually the best compromise. It avoids interrupting your day and uses the most stable network connection.
Common mistakes Shark 6 owners make with OTA updates
- Starting an update with low battery. The vehicle cannot charge during the process. Top up first.
- Trying to move the vehicle mid-update. Most functions are locked, including the powertrain.
- Updating on weak mobile signal. Failed downloads waste battery and time. Use Wi-Fi when available.
- Plugging in OBD-port devices during an update. The manual specifically warns against this.
- Assuming a failed update has bricked the vehicle. Retry first. Most failures recover cleanly.
- Ignoring the upgrade prompt for months. Cybersecurity, BMS, and ADAS fixes matter. Don't delay indefinitely.
OTA updates keep your Shark 6 sharper, safer, and more efficient over time. The process is straightforward: park in P, ensure a strong network connection, accept the prompt, and leave the vehicle alone until it finishes. Use Wi-Fi for large updates, mobile data for smaller patches.
