Added advice to remove the VTS subscription
Condition
The customer reports that the battery has insufficient voltage to start the vehicle. The workshop confirms this
condition and notes an unexpectedly high current draw from the ConBox. Sometimes, the workshop also notes an
unexpected active alarm on the vehicle. Be sure to gather any information you can about how the customer used the
vehicle before the breakdown.
Technical Background
The ConBox makes a higher than normal quiescent current draw. This may relate to an active alarm or another
condition. Likely, the active alarm is consequential to the battery drain and did not cause the battery drain.
Be aware: Sometimes, technicians pull fuses to determine which ECU is causing an unwanted current draw. Do not 		
do this in this case! Pulling the ConBox fuse or disconnecting the ECU in any way, while the vehicle is not in ‘Service
Mode’ will cause an alarm activation in the PVTS (Connect) backend.

There are two noteworthy ConBox ECUs related to this issue: ConBox Low and ConBox High. Both the 9YA/9YB
and 992 have ConBox Low installed in production until June 2021. For vehicles with ConBox High installed, the
following service information is not applicable. To determine which ConBox is in the subject vehicle, note the
following information:
•
•
If ConBox High is installed in the vehicle, the VAL will contain the label: “Connect (High).”
If ConBox Low is installed in the vehicle, the VAL will contain the label “Connect” or “Connect (incl. PVTS).”
ConBox High is installed only on models that have PCM6. PCM6 appears on newer models, including MY22 and
newer 9YA/ 9YB and 992. PCM6 has more connected functionality than ConBox Low can provide, therefore ConBox
Low and ConBox High are not interchangeable.
Service Information
There are no current software updates or solutions for ConBox High in 992 and 9YA/9YB. The current software 		
version for 992 and 9YA/ 9YB ConBox High is 0360.
For ConBox Low on both 9YA/9YB and 992, note the following two action plans and consider the customer’s needs.
Action A: Software Update
This action will update the ConBox software and mitigates the issue. However, we do not know how effective this 		
solution is.
Procedure
1.
Be sure to take a before-repair VAL.
2.
Please address the 12V system by either charging, or
		
replacing the 12V battery, as necessary.
3.
Charge the 3.5V ConBox backup battery in the vehicle.
		
The vehicle will only charge this backup
		
battery while the ignition switch is on (Terminal-15). If
		
the battery will not charge acceptably, replace it.
4.
If an active alarm is present in the ConBox (see figure 1
		
for an example for the VAL), please reset the alarm
		
using one of the following methods:
		a.
(Useful whether or not the customer has an
			active Connect subscription.) File a Connect
			
PRMS ticket to cancel the alarm status. Within
			
48 hours, Porsche suppliers will reset the alarm
			
status. Note: the car has to have good reception.
			
Be sure to park the vehicle outdoors.

		b.
(Only useable if the customer has an active Connect subscription.) Make sure vehicle remains
			
outside through this process. Trigger the alarm and let it sound for about a minute.
			
The customer will then receive a call from the Vodafone Secure Operating Center and have to
			
answer pre-determined security questions. Since this method requires customer interaction, help
			
prepare the customer for Vodafone’s call. 		
5.
After the alarm has been reset:
		See the table below and update the software accordingly, to the highest level possible. It is not possible to 		
		
update the ConBox with an active alarm.
6.
Once the ConBox is updated:
		
•
Make sure the 12V battery is charged.
		
•
Initiate a new standing phase, by driving the car around the block with good connection.
		
•
After you stop driving, prepare the vehicle for a quiescent current test. Lock the vehicle and make 		
			
sure no can set an alarm by opening the door or disturbing the interior monitoring.
		
•
Measure the quiescent current for four hours and attach the test results graph to the PCSS job.
		
•
Take an after-VAL.
7.
If the current draw is still present, please file a Technical Support PRMS ticket.
8.
Do not pull fuses to determine what is causing the current draw.
Action

Programming code: E3D7K
Programming code: A3D7K
Action B: Remove VTS Subscription
This is a temporary workaround. This procedure will remove the VTS service subscription from the vehicle.
Be sure to discuss this option thoroughly with the customer. Note: In some cases, the customer may have
previously needed to activate services in order to align the vehicle’s alarm status with the backend and
help with a related issue. Now, we will remove these services and restore the original VTS subscription
state.
Procedure
1.
Click this link and follow the prompts to request subscription cancellation:
		https://forms.office.com/r/SZFbi8Yk54
2.
Inform the customer that VTS services are now no longer available. Also, tell the customer to 		
		
expect an email with further details.
