Update of vehicles affected
Condition
The workshop cannot commission the PCC/PVTS control unit using the PIWIS tester. Consequently, the customer
will not be able to use VTS remote services. Sometimes VTS remote services that previously worked will stop working.
Technical Background
When commissioning or using VTS, the PCC/PVTS control unit must connect to an active GSM network. Starting in 		
2022, 3G mobile networks are no longer active, so the ECU must find a 4G network. The issue occurs because the
subject vehicle’s PCC/PVTS control unit gets confused and looks for a 3G network instead of looking for a 4G network. Because of a bug, it stops looking for other networks and becomes stuck attempting to connect to the disabled 3G network.

Service Information
The workshop must replace the PCC/PVTS control unit to fix this
condition. The desired part number is 958.035.620.J. The ECU label
should show software version 0924. (See figure 1. This is a ‘good’ part.)
Figure 1
If you receive this part with a software version lower than 0924, please submit a Parts Claims and Returns PRMS 		
ticket to your Area Parts Support Specialist for further instructions. (See figure 2 for ‘bad’ part examples.)
