Incoming inspection
A vehicle with high-voltage (HV) technology comes into the workshop due to a problem.
Diagnosis of the HV vehicle
Using the X-431 EURO TAB III, the HV ADD-ON Kit & EG100 current clamp,
a comprehensive diagnosis is carried out.
Error detection
A fault is detected in a cell of the HV battery.
Safety steps
The HV system is de-energised according to the manufacturer’s specifications.
Battery removal
The HV battery is removed using the specially developed TLT610 lifting system.
