The PASSKey III vehicle theft deterrent system deters
drive-away vehicle theft. This system enables vehicle operation only when
the ignition key mounted identification device, also known as the PASSKey III
coded key, is properly identified. This system provides these vehicle theft
deterrent features:
| • | A PASSKey III coded key interface. |
| • | A control of the SECURITY indicator lamp located in the instrument
panel cluster. |
| • | Class 2 serial data communications interface available at the
Data Link Connector (DLC) for diagnostic purposes. |
This system contains a theft deterrent module, which provides the following
major functions:
| • | Allows for normal fuel delivery to the engine upon detection of
a valid PASSKey III coded key. |
| • | Notifies the driver of the system status through the SECURITY
indicator lamp located in the instrument panel cluster. |
| • | Provides diagnostics via Class 2 serial data through the Data
Link Connector (DLC). |
The interface between the theft deterrent module and the PASSKey III
coded key is non-contacting. The theft deterrent module accommodates up to
10 keys, each with an identification code. The valet key is electronically
distinguishable from a regular key. The valet key has a gray head and a regular
(master) key has a black head.
