Error Code During ECU Upgrade (7000-C8-0001)

Symptom

The “7000-C8-0001” error occurs when starting an ECU upgrade or during the upgrade process, and the upgrade stops immediately.

Cause

• Socket connection failure with the gateway, particularly a non-CCU type gateway
• Static IP address not configured on the tablet or incorrect IP settings
• Faulty or disconnected ECI/VCI cable
• Gateway communication interference caused by aftermarket devices
• Google Play system update not applied or unstable tablet PC OS environment

Resolution

Step 1) Recheck the Ethernet Static IP Address

In the tablet settings, verify that the Ethernet static IP address is configured correctly.
(The settings are frequently reset after an Android OS update.)

Step 2) Inspect the Cable and Equipment Connections

When using VCI3, verify the wired USB connection. When using VCI2, verify the ECI cable connection.
If a cable is suspected to be faulty, perform a cross-check using another cable.

Step 3) Update the Tablet OS/Google Play System

Check whether the latest Google Play system update is installed and update it if necessary.
Restart the tablet after the update.

Step 4) Reset the Vehicle Battery Power

Caution: Disconnecting the negative (-) battery terminal may reset certain vehicle settings.

1) Disconnect the vehicle’s negative (-) battery terminal.
2) Wait at least 5 minutes until all control units (ECUs) are completely powered off.
3) Reconnect the battery, and then retry the control unit upgrade 2-3 times.

Step 5) Remove Aftermarket Devices

Remove all devices that may interfere with the gateway, such as dash cams, communication modules, and taxi equipment.
