VCI connection failure with persistent 0V voltage on the Autel IM608 II (MaxiFlash JVCI+) indicates a communication-level fault that may require hardware inspection if log analysis confirms internal failure.
Problem Overview
This issue appears when the VCI fails to communicate with the vehicle during diagnostics, while the system continuously displays 0V voltage.
It is a common fault state that can be triggered by either communication disruption or internal VCI malfunction, so it cannot be diagnosed based on symptoms alone.
Log Upload Steps (Required for Diagnosis)
To proceed with troubleshooting:
- Open Maxitool App → VCI Settings
- Enable all Enhanced Logging options
- Run a VCI connection test or reproduce the failure
- Go to Log Collection → Select “Once” → Start → Upload
- Wait until “Upload Completed” appears
Logs will then be sent to Autel Technical Support for analysis.
Technical Outcome Path
After log review, the issue is classified into one of two categories:
- Software / communication issue → requires configuration or firmware-level correction
- Hardware failure → requires VCI inspection and possible repair
If internal damage is confirmed during inspection (e.g., VCI board fault), the MaxiFlash JVCI+ module will require factory repair or replacement.
Result
Final Autel IM608 Pro2 diagnosis depends on log analysis, and in some cases physical inspection of the VCI hardware.
