2 About This Product
The Personal Assistance and Safety System (PASS) serves as the central platform of a telematics system,
where all telematics-related technologies are deeply integrated. PASS communicates to a central service
center through the communication network device and in turn the service center helps deliver telematics
services to the customer.
PASS handles the communication from the vehicle to the outside infrastructure via various wireless systems.
Besides, a localization manager will ensure proper positioning information for all telematics services.
PASS contains a GPS receiver, cellular transceiver, and modem/transceiver control board.
PASS supports all the telematics services, which are listed below:
•
•
•
•
•
•
Remote Door Unlock
Road Side Assistance (R-Call)
Emergency Assistance (E-Call)
Automatic Crash Notification (CAN)
Stolen Vehicle Tracking
Automatic Maintenance
The access to PASS system functionality is granted via several application programming interfaces from
within the platform or to other in-car applications over the vehicle network system. In that way the
application software will become independent from the used hardware.
PASS can be characterized as a distributed, heterogeneous hardware/ software system, which provides
functionality and services to the customer via the interaction of several devices. These hardware components
are interconnected by standardized car networks (e.g. Discrete I/O line, CAN bus) and by wireless
communication channels (e.g. GSM).
The features accomplished UConnect System Include:
- Bluetooth Hands Free Calling
- Universal Consumer Interface (Portable Music Player Integration)
Additional investigate features are:
- Remote Vehicle Diagnostics and Data Collection
- Off Board Navigation
A separate RFI will also be issued to Customer Service Center operators to provide the ‘back-end’ services.
It is assumed that communication will take place via an integrated cellular modem although other innovative
solutions are always considered.

3.2 Roadside Assistance Overview
The Roadside Assistance service allows the customer to get in touch with the Service Center in case of a
breakdown of the vehicle or for any non-emergency assistance. A request for the Roadside Assistance can
be triggered by manually pressing a button available within the car. This service allows the service center to
provide quick and efficient assistance to the customer. The service can also be triggered automatically when
predefined thresholds (remaining distance, remaining time) have been reached.

PASS-TCU User Manual
5 Definitions and Acronyms
OTA: Over the Air
Ambient Temperature: Temperature surrounding the component as tested in a test chamber or as installed
in the vehicle.
Category and subcategory: In this document, electronic modules, electric motors and inductive devices are
classified into categories and subcategories, which determine the appropriate test requirements.
ECU: Electronic Control Unit
DUT: Device Under Test
Component: Any electrical or electronic assembly used in the vehicle, such as engine control module,
instrument cluster, junction block, sensor, switch, etc. Also used interchangeably with terms such as ECU,
Module, Device, DUT, etc.
Ignition Voltage Lines: The supply voltage lines to a DUT that are fed from the vehicle electrical power
distribution system through the ignition switch.
Inductive Device: An electromechanical device that stores energy in a magnetic field. Examples are
solenoids, relays, buzzers and electromechanical horns.
IOD: Ignition Off Current Draw.
IP Class: International Protection classification for solid and/or water intrusion for automotive applications
as described in DIN 40 050.
RKE: Remote Keyless Entry
TPM Sensor: Tire Pressure Monitor Sensor
Non-operational: A component shall be considered “Non-operational”, if it is connected to a power source,
but does not perform any normal operating functions during the test. The condition requires use of mating
connectors during the test. This condition is similar to the one experienced by an E/E component in a parked
vehicle.
NTC: Negative Temperature Co-efficient (Device with NTC feature shuts off power supply or reduces
certain component applications (e. g. CD-playing for a car radio) when device temperature goes below
certain minimum operating temperature specified).
Operational: A component shall be considered "Operational", if it performs functions as experienced during
vehicle operations on a continuous basis (without any interruptions). Power source may be from vehicle
battery, ignition feed or an independent power source, as in case of, RKE, or TPM Sensor, etc.
PET: Parametric Evaluation Technique.

Power-off: A component shall be considered "Power-off", when it is not electrically connected to a power
source, as in case of shipping or storage conditions. “Power-off” condition may require use of mating
connectors during some of the tests and shall be specified clearly in the “Test Parameters”.
PTC: Positive Temperature Co-efficient (Device with PTC feature shuts off power supply or reduces certain
component applications (e. g. CD-playing for a car radio) when device temperature goes above certain
maximum operating temperature specified).
PV: Production Validation.
Soak Time (Tsoak): Time taken by component to reach chamber ambient temperature at high or low
temperature during thermal cycling tests from the time chamber temperature reaches corresponding high or
low temperature levels.
Temperature class: Classification of maximum temperature a component will experience based on its
mounting location and specific packaging variations in the vehicle.
Tmin: Lowest ambient temperature experienced by any component (Usually -40 0C).
Tmax: Highest ambient temperature experienced by any component. Value of Tmax depends on temperature
class of the component.
Usage Life Profile (ULP): It is a software tool that assists in selecting the applicable qualification tests and
test parameters for a component based on input data such as design or service life, in-vehicle component
location, customer driving/usage pattern or other environmental stresses.
Vibration Class: Classification of vibration intensities a component will experience based on its mounting
location in the vehicle.
