AMA2 - Replacing Seat Occupancy Detection System for Passenger Seat (USA/Canada)
(Recall Campaign)
Revision:

This bulletin replaces bulletin Group 6 50/21 AMA2, dated November 4, 2021.

Model Year:

As of 2015 up to 2018

Important:

CRITICAL WARNING -This campaign includes steps where control unit(s) in the vehicle will be
programmed with the PIWIS Tester. The vehicle voltage must be maintained between 13.5 volts and 14.5
volts during this programming. Failure to maintain this voltage could result in damaged control unit(s).
Damage caused by inadequate voltage during programming is not a warrantable defect. The technician
must verify the actual vehicle voltage in the PIWIS Tester before starting the campaign and also document
the actual voltage on the repair order.

Model Line:

Macan

Equipment:

Country equipment USA (C02)/Canada (C36)

Concerns:

Seat occupancy detection system for passenger seat

Information:

Sensor mats for seat occupancy detection, on which the conductive fabric can break, were
installed in the passenger seat on the affected vehicles.
If the conductive fabric breaks, the front airbags on the passenger's side will be deactivated because
correct seat occupancy detection can no longer be guaranteed. The airbag warning light and Passenger
Airbag OFF light will be activated in order to alert the driver.

Action required: Replace the seat occupancy detection system according to the campaign scope assigned to the
respective vehicle.
Information
To find out which campaign scope is assigned to the respective vehicle for replacing the seat
occupancy detection system, see PIWIS Vehicle Information.
The part numbers of the parts required for the respective vehicle are specified in the assigned scope
for “Replacing seat occupancy detection system for passenger seat".
For an overview of the campaign scopes, see:  Technical Information 'Warranty processing'
Affected
Vehicles:

Only vehicles assigned to the campaign (see also PCSS Vehicle Information).

Spare parts information
Information
When replacing the occupant classification components,
all coordinated components (padding, sensor mat and
control unit) in the repair kit must be replaced.
Due to worldwide semiconductor bottlenecks at individual
suppliers, we were unfortunately unable to include the
corresponding occupant classification control units in
the repair kit as part of this campaign.
To avoid delay in the implementation of this measure, the
occupant classification control unit installed in the
vehicle is reused in this particular case.

– Padding with affixed sensor mat - replace
– Occupant classification control unit - reuse

When implementing this measure, pay particular attention
to the following:

Contents of occupant classification system repair kit

•

The sensor mat for the occupant classification system must not be removed from the foam part.

•

Mixed installation, e.g. “old” padding and “new” sensor mat, is not permitted.

•

The existing control unit for occupant classification must not be removed and must be reprogrammed with the provided programming box.

•

The one-time procurement of the required programming box can be found in the section "Required
tools".

•

The direct programming of the control unit occupant classification with the currently valid
software is only approved and released within the scope of this campaign.

•

After carrying out this campaign, in the event of a further repair case, the usual repair concept
with complete replacement of all components (including control units) for occupant classification must be used.

Information
Between delivery of the padding to its installation in the front seat, the glued sensor mat can partially
detach from the foam part over longer periods of time. This does not constitute a material defect and
will have no influence on the quality of the sensor mat.

Overview of padding
If the sensor mat has come loose as shown in the picture, then the sensor mat must be pressed back in
place before installation as shown in pictures A, B, C.
Complete adhesive strength is only achieved after attaching or clamping the seat cover.

Required tools
Information
Purchasing the "AMA2 ReProgramming Tool" programming box
A special programming box is required to program the occupant classification control unit with the
software required for the padding including sensor mat. This programming box, including its wiring
harness, can be obtained from the online shop of TKR Automotive GmbH.
One programming box is provided for each affected Porsche dealer. Only one programming boxmay
therefore be ordered for each affected Porsche dealer.
