1. Functional Description - Comfort Access System (CA)
1.1 General functional description
The CA-system enables convenient utilization of the vehicle. To use the vehicle, the
driver only needs to take the key along with him/her. The vehicle communicates with the
system inductively via antennas. These antennas are located in the rear bumper, in the
trunk, of the backlite shelf and in the interior. These antennas are driven inductively with
a frequency of 125 kHz. The system's range is limited in a defined fashion by damping
the body sheet metal. In the vehicle interior, the ranges of the various antennas overlap,
which enables location of the key.
1.2 Passive access control
Controlled by TAGE (outside door handles electronic)
1.3 Passive Go (start/stop)
The system provides the function which enables starting/stopping the engine without
key actuation.
The prerequisite for starting the vehicle is a key allocated to the vehicle, which is taken
along by the user and is clearly inside the vehicle. By actuating the starting device, the
driver starts the identification process, i.e. the PGS control unit issues a request for a
valid key inside the vehicle. The key returns an appropriate response to the PGS control
unit. In case of successful identification of the key, the vehicle is started and the
immobilizer is deactivated.

7.1 FCC Declaration
FCC ID LX8PGS
This device complies with part 15 of the FCC Rules. Operation is subject to the
following two conditions:
(1) This device may not cause harmful interference, and
(2) this device must accept interference received, including interference that may cause
undesired operation.
Caution: Any changes or modifications not expressly approved by the party responsible for
compliance could void the user's authority to operate the equipment.
8. Power up of test samples
The test setup consists of the following components:
•
•
•
•
Control unit:
Wiring harness:
Antennas:
Power Supply:
PGS2; 5WK4 9135
Control unit ↔ bumper antenna and power supply
1 bumper antenna 5WK4 9133
14VDC or car battery (not supplied)
The bumper antenna will represent the max. allowed inductive load, which the control
unit can supply.
8.1 Test configuration and operation
Connect the wiring harness to the control and the bumper antenna. More precise
allocation of connector - socket is not necessary, as all connections are mechanical or
color-coded. The entire test setup is connected to power via the two banana jacks on
the wiring harness.
Banana jack, red = 14VDC or car battery
Banana jack, blue = GND (ground)
The power consumption in case of operation amounts to max. 10A.
If the power supply is connected the control unit begins to operate. The connected
antenna will transmit the carrier frequency with a duration of approximately 40ms at
intervals of 500ms. The transmitter power of the control unit is adjust by 100%.
This procedure does not correspond to the standard mode of operation! This
procedure is only used to simplify emission measurements.
