Symptom: Error code [9000-36-7000] occurs during an ECU upgrade.
Cause: This error occurs when the control unit does not respond to the ECU upgrade data transmission command sent by the ECU app, or when the specified response time is exceeded.
Solution:
1. Check whether any aftermarket equipment is installed in the vehicle.
2. Verify that the diagnostic tool is properly connected and that the target control unit's sensor output is displayed correctly.
3. If the connection status and sensor output are normal, disconnect the vehicle power connector, wait 5 minutes, reconnect it, and then retry the ECU upgrade.
