GENERAL OPERATION
SYSTEM OPERATION
The PATS system is a PASSIVE Anti-theft system which requires no
special procedures for the driver to arm or disarm the system. The
system is operated by a transponder fitted within the ignition key’s
body, which communicates with the PATS module transceiver
mounted around the lock barrel.
The easy method of identifying a PATS vehicle is if the key has a
small imprint showing where the transponder is fitted. The code for
the transponder is stored in memory within the PATS amplifier or the
Engine Management ECU, Dash panel or Drive Train ECU.
The PATS system reads the code when the ignition key is turned
from position 0 to position 1. If the correct code is received then the
engine will start.
KEY PROGRAMMING
NOTE : Clear ALL Fault codes before programming.
Master keys can only be programmed using the 2 PATS keys (A and
B) the WDS or the AD100 system.
NOTE : In some cases the vehicle doors must be closed to perform
the re-programming sequence.
Further slaves can be added without any specialist equipment as
follows :-
1. Insert key A, and turn to Position 2.
2. Turn back to Position 0, and remove key A.
3. Insert key B, and turn to Position 2.
4. Turn back to Position 0, and remove key B.
5. Insert the new slave key and turn to Position 2.
6. Remove new key. Key is now programmed.
7. Procedure can be repeated after 20 seconds, for up to 8 slave
keys.
NOTE : If programming is unsuccessful, the PATS LED will flash
when the key is inserted.
