Programming the Selectable Features

1.

To start programming, make sure that the Theft Deterrent System is disarmed, either by using a remote transmitter that is cur-
rently programmed, or by using the Theft Deterrent System Override procedure.

2.

Gain access to the programming push button switch located on the keyless entry control module, which is mounted in the
center console of the vehicle.

3.

Turn the ignition key to the “ON” position.

4.

Within 15 seconds, press and release the programming Switch 3 times. The vehicle's horn will sound one time indicating that
the system is in remote transmitter program mode.

5.

Immediately turn the ignition key off (3 chirps indicates exit remote transmitter program mode) and then back on. The
vehicle's horn will sound 2 chirps indicating that the system is in feature programming mode.

6.

Press and release the programming switch on the keyless entry module 1 time to advance to feature number 1. The vehicle's
horn will chirp 1 time if feature 1 is in the “ON” position, or 2 times if feature 1 is in the “OFF” position

7.

To change the feature, press and release the “LOCK” button on the keyless entry remote transmitter, and the appropriate 1 or 2
chirp signal from the horn will identify the new selection for that feature (Refer to the table shown above).

8.

To advance to selectable feature number 2, press and release the programming switch on the keyless entry module a second
time, and again the vehicle's horn will identify the selection of that feature. Use the lock button on the keyless entry remote
transmitter to change the feature or proceed to the next step if no change is desired

Active or Passive Alarm Arming.

Factory Pre Set = Active

When this feature is selected
“ON” or “ACTIVE” the Theft
Deterrent System will only arm
after the “LOCK” button on the
transmitter is pressed. (The doors
will automatically lock).

When this feature is selected “OFF”
or “PASSIVE”, the Theft Deterrent
System will automatically arm 30
seconds after the ignition key is
turned off and a door is opened then
all doors are closed.

5

Active or Passive Door Locking

Factory Pre Set = Active

When this feature is selected “ON”
or “ACTIVE”, the vehicle’s doors
will only lock when the “LOCK”
button on the transmitter is pressed.

When this feature is selected ”OFF” or
“PASSIVE”, and feature number 4 is
set to “PASSIVE”, all doors will auto-
matically lock 30 seconds after the
ignition key is turned “OFF” and a door
is opened then all doors are closed.

9.

To advance to the next selectable feature press and release the programming switch on the keyless entry module. The vehicle’s
horn will identify the selection of the next feature. Continue this way until all desired features are activated or disabled per
customers request.

10. Turn the ignition key off or allow 15 seconds to pass, and the vehicle's horn will sound 3 chirps indicating programming mode

has been terminated.

Feature Programming Hints

1.

Unless otherwise specified, if you wait more than 15 seconds between steps in the programming mode, the system will auto-
matically terminate the programming mode. This is indicated by the 3 chirp signal from the vehicle's horn. Simply start over to
complete programming of all features.

2.

Test the system to be sure that all selectable features are functioning according to your customers requests. If you have missed
a feature or changed the wrong feature, simply re-enter the feature programming mode to make the appropriate changes.
