Update of Actions & Procedures

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, perform all four listed action plans.
Action 1: Preliminary Work and Remove Active Alarm
Procedure
1.
Be sure to take a before-repair VAL.
2.
Important: Do not pull fuses to determine what is caus
ing the current draw. This can trigger an alarm in the

VTS system and obscure the cause of the draw.
3.
Please address the 12V system by either charging, or

replacing the 12V battery, as necessary.
4.
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.
5.
Important: You must ensure the vehicle no longer regis
ters an active alarm. You can check this in the actual

values of the ConBox, using the PIWIS tester.

(see figure 1 for an example from the HTML version of

the VAL) If an active alarm is present in the ConBox,
please reset the alarm using one of the following meth ods:

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.
Action 2: Software Update
This action will update the ConBox software and mitigate the issue. However, we do not know how effective this
solution is.
Procedure
1.
After the alarm has been reset or confirmed not to be active, see the table below and update the software,

to the highest level possible. It is not possible to update the ConBox with an active alarm.

2.
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.
3.
If the current draw is still present, please file a Technical Support PRMS ticket.

Action 3: Remove VTS Subscription
This is a temporary workaround. This procedure will remove the VTS service subscription from the vehicle and offer
the customer a refund. 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 cancel the security services to mitigate
the battery draw.
Procedure
1.
Click this link and follow the prompts to request subscription cancellation:
https://forms.office.com/r/SZFbi8Yk54
2.
Confirm the VTS service contract is no longer in effect. You will receive an email confirming this.
3.
Important: You must ensure the vehicle no longer has an active VTS Contract. You can check this in the

actual values of the ConBox, using the PIWIS tester. (See figure 3 for a screenshot of the PIWIS tester –

actual values of the ConBox shown.)

Figure 3
4.

Inform the customer that VTS services are now canceled. Also, tell the customer to expect a confirmation
email and refund to the source of their original payment method.

Action 4: Replace the ConBox
This procedure will give the customer a new ConBox and allow PCNA to analyze the original part.
Note: Disconnecting the ConBox while the alarm is active or the contract is active will set the alarm, cause trouble
for the repair, and make the removed ConBox useless for future analysis.
Procedure
1.
After the confirming removal of the subscription in action 3, replace the ConBox using workshop manual
instructions.
2.
Ensure the replacement ConBox has the highest level of software available. (See Action 2)
3.
The original ConBox will be requested by PCNA for delivery.
