This article provides troubleshooting steps for Ethernet-required ECU Upgrade failures using KDS 2.0 diagnostic devices. It covers causes such as incorrect tablet IP configuration, outdated software, or unstable connections, and details resolutions including hardware checks, IP settings, app permissions, OS updates, power resets, and technical support contacts if issues persist.
Quick links
Applies to
Ethernet‑required ECU Upgrade workflow using:
- VCI2 + ECI (wired Ethernet path)
- VCI3 + 9‑pin USB cable (Ethernet over USB)
- KDS 2.0 diagnostic device and Android tablet
Symptom
- ECU Upgrade fails with an error code (XXXX‑XX‑XXXX)
- Find the error code ⧉
Cause
- Incorrect or missing tablet Fixed‑IP configuration
- Outdated Android OS or Google Play System update
- Unstable VCI2/VCI3 power or incomplete connection
- Temporary ECU/vehicle-side communication stall requiring power reset
Resolution
Step 1) Verify correct Ethernet hardware connection
Note:
System or OS updates may reset manually configured Ethernet settings. Please verify and reconfigure the settings after an update if necessary
Confirm the exact connection method required for Ethernet upgrades:
-
VCI2 + ECI: OBD → ECI → VCI2 → Tablet
PLEASE NOTE:
Ensure all connectors are firmly seated and cables are not bent or damaged.
-
VCI3 + 9‑pin USB cable: OBD → VCI3 → 9‑pin USB → Tablet
PLEASE NOTE:
Ensure all connectors are firmly seated and cables are not bent or damaged.
Step 2) Verify static/fixed IP setting in tablet settings
- Tap the Recent apps button (□) in the navigation bar.
- Open Android settings and navigate:
- Variant A: Settings → Connections → More connection settings → Ethernet → Configure Ethernet device
- Variant B: Settings → Network & Internet → Ethernet → Configure Ethernet device
- Set the following static IP and tap [Save]:
- IP address: 10.0.128.0
- Netmask: 255.0.0.0
- DNS address: 8.8.8.8
- Default gateway: 10.0.128.0
- Proxy: None
Step 3) Confirm App permissions and Android OS & Google Play System update
A. App Permission – GITMCommManagerService
When you carry out an ECU Upgrade, KDS 2.0 asks for missing app permissions.
Please make sure to tap [OK] or [Allow].
Manual app (GITMCommManagerService) permission allowance:

B. Android OS & Google Play System update
- Open Settings on the tablet.
- Go to About tablet → Software information.
- Select Google Play system update.
- Ensure the tablet is fully updated (minimum: Android OS 13 + Google Play System 2024 or later).
Step 4) After completing Step 1–3, if ECU Upgrade still fails
Warning: Vehicle battery removal requires safe working conditions.
- Disconnect the vehicle battery.
- Wait at least 5 minutes for all ECUs to fully power down.
- Reconnect the battery and retry the ECU Upgrade process 2–3 times.
Step 5) If the symptom persists, reboot the tablet
- Turn off the tablet completely.
- Wait ~10 seconds.
- Turn it back on and attempt the upgrade again.
