Preliminary work for measurement 5
(Check: High-voltage line from high-voltage distributor to high-voltage charger)
- Remove dome strut.
> 408619 REMOVING AND INSTALLING STRUT (DOME STRUT) - on "Removing"
- Unscrew and disconnect traction line (from high-voltage distributor to front power electronics).
Traction line from high-voltage distributor to front power electronics
- Release and disconnect high-voltage line (from high-voltage distributor to high-voltage charger) at the high-voltage distributor.
High-voltage line from high-voltage distributor to high-voltage charger
- Connect and tighten traction line (from high-voltage distributor to front power electronics).
- Connect high-voltage test adapter > VAS 6558/9-6A - High-voltage test adapter
between high-voltage line (from high-voltage distributor to passenger compartment heater) and high-voltage distributor.
Measurement 5
- Perform measurement 5.
- 6.1 Setpoint value ≥ 1.1 MOhm
- Evaluate measured result
- 7.1 If the measured value is within
the setpoint value range, replace high-voltage line (from high-voltage distributor to high-voltage charger).
After replacing the high-voltage line, repeat measurement 4.
- 7.2 If the measured value is outside of the setpoint value range, continue with measurement 6 .
- 7.1 If the measured value is within
the setpoint value range, replace high-voltage line (from high-voltage distributor to high-voltage charger).
