Anti-Carjacking can be made even more difficult to defeat with the use of “Coded Over-
ride” (Feature
#
1). Instead of 1 Valet Switch press to turn it off after fully engaging,
multiple presses must be made. The number of presses, 1 through 9, are chosen and
programmed by the user Even if a customized Coded Override is used, only one Valet
Switch press is needed to cancel Anti-Carjacking before it fully engages at 60 seconds; after
that point that the correct custom Coded Override must be entered to turn off Anti-Carjacking.
How to program Coded Override:
•
Feature
#
1 allows the user to custom-program the “Coded Override”. Place the MARS
into Features Programming Mode (page 12) and access Feature
#
1. After the Status
Light flashes once and the horn chirps once to confirm that Feature
#
1 is ready for pro-
gramming, press the transmitter “LOCK” button for each digit of the desired customized
Coded Override, but wait after each single “LOCK” button press for a single Status Light
flash and horn chirp before pressing the button again for the next digit. When all of the
digits have been entered in this fashion, wait for the Status Light and horn to flash and
chirp the complete total number.
Example: for a Coded Override of “3 presses”, programming would be: enter Features
Programming Mode, select “feature 1” (
response is 1 flash / 1 chirp). Press “LOCK”, wait
for
1 flash / 1 chirp; press “LOCK” again, wait for 1 flash / 1 chirp; press “LOCK” again, wait
for
1 flash / 1 chirp. Now continue to wait, until the MARS has 3 flashes / 3 chirps. Exit
programming mode, and the Coded Override is now 3 presses of the Valet switch.

9, “Unlock Doors With Trunk Release” has the doors unlock automatically when
ever the remote trunk release is used. If this feature is turned off (press “UNLOCK” in
programming, page 12), the trunk release will still operate when used, but the doors will

Note: If a security system is present which utilizes a starter interrupt circuit, the
Green wire must be connected to the Starter Motor side of the interrupt.

Connect the Yellow wire to the vehicle's Ignition wire (also known
as “Primary Ignition”). This wire will show +12 Volts when the ignition key is in the "Run"
and "Start" positions and no voltage in the "Off" and "Accessory" positions. This wire is
found in the ignition switch wiring harness (see diagram on previous page).
Note: If two Primary Ignition wires are present, use the Yellow/Green wire for the second,
or configure an optional relay to the 3-pin Red port (see pages 26-27).
12-Gauge Yellow Wire:
Ignition Output
Connection Required.
Connect the White wire to the vehicle's Accessory wire. This
circuit supplies power to the Heat, Ventilation and Air Conditioning (HVAC) system. This
wire will show 12 Volts when the ignition key is in the "Run" and "Accessory" positions and
No voltage in the "Start" and "Off" positions. The connection point for this wire is also found
in the ignition switch wiring harness.
12-Gauge White Wire:
Accessory Output
Connection Required.
12-Gauge Yellow/Green Wire:
Programmable Output
Connection If Needed.
The Yellow/Green wire is an additional output which can be
programmed to operate as an Ignition output, Accessory output or Starter output. As re-
ceived, it is programmed as an Ignition #2 output. This wire may be used in cases where
the vehicle has more than one of any of these three circuits.
