Technical Service Bulletin
Technical Background
The charging socket was modified in production.

Production Solution
From Q2 2020, only the new-generation high-voltage wiring harness for the charging socket is fitted in production
vehicles.

Service
It is essential to check the part number of the removed original high-voltage wiring harness and of the new
replacement high-voltage wiring harness.
No further service measures are necessary if the following table applies:

Table 1.2: Further measures required TSB applies.
If the high-voltage wiring harness for the charging socket is replaced as listed in Table 1.2, an SVM code will need
to be performed and a replacement test plan performed.
SVM Update Instructions

To prevent the high-voltage battery from charging during the software update, the high-voltage
charging cable on vehicles with high-voltage components must be unplugged BEFORE the SVM code is
entered. Charging the high-voltage battery during a software update can cause damage to the highvoltage components.

The parking brake must be released and the diagnostic interface must be hardwired into the scan tool.

1. Follow all instructions in TSB 2011732: 00 Software Version Management (SVM), operating instructions.
2. Update the On-Board Battery Charger (J1050) using the SVM action code as listed in the table below, if
necessary:
