fcc/id notice This device complies with Part 15 of FCC rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) This device must accept any interference received, including interference that may cause undesirable operation. Changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate this device.
■ After the remote start module has been installed, test the remote start module in accordance with the Safety Check outlined in this installation guide. If the vehicle starts when performing the Neutral Safety Shutdown Circuit test, the remote start unit has not been properly installed. The remote start module must be removed or properly reinstalled so that the vehicle does not start in gear. All installations must be performed by an authorized Directed Electronics dealer.
deciding on component locations locations for the siren Some things to remember about mounting the siren: ■ Keep it away from heat sources, such as radiators, exhaust manifolds, turbochargers, and heat shields. ■ Mount it where a thief cannot easily disconnect it, whether the hood is open or shut. Both the siren and its wires should be difficult to find. This usually involves disguising the wire to look like a factory harness. ■ We recommend against grounding the siren to its mounting screws.
dash fuse box, or above the radio. mounting the antenna The antenna position should be discussed with the vehicle’s owner prior to installation, since the antenna may be visible to the vehicle’s operator. The best location for the antenna is centered high on either the front or rear windshield. For optimal range, the antenna should be mounted horizontally. It can be mounted vertically but range will be diminished.
locations for valet/program switch IMPORTANT! When the vehicle is delivered, please show the user where this switch is located and how to disarm the system with it. Ensure that the location you pick for the switch has sufficient clearance to the rear. The switch should be well hidden. It should be placed so passengers or stored items (such as in a glove box or center console) cannot accidentally hit it. The switch fits into a 9/32-inch hole. T DRAFTF A R D This system has Remote Valet.
locations for the optional starter kill relay If optional starter kill relay or its connections are immediately visible upon removal of the under-dash panel, they can easily be bypassed. Always make the relay and its connections difficult to discern from the factory wiring! Exposed yellow butt connectors do not look like factory parts, and will not fool anyone! For this reason, routing the optional starter kill wires away from the steering column is recommended.
finding the 12V switched ignition wire The ignition wire is powered when the key is in the run or start position. This is because the ignition wire powers the ignition system (spark plugs, coil) as well as the fuel delivery system (fuel pump, fuel injection computer). Accessory wires lose power when the key is in the start position to make more current available to the starter motor. How to find (+)12V ignition with your multimeter: 1. Set to DCV or DC voltage (12V or 20V is fine). 2.
turn over, you have the right wire. finding the accessory wire An accessory wire will show +12V when the key is in the accessory and run positions. It will not show +12V during the cranking cycle. There will often be more than one accessory wire in the ignition harness. The correct accessory wire will power the vehicle's climate control system. Some vehicles may have separate wires for the blower motor and the air conditioning compressor.
polarity is negative (ground while the bulb is on). 6. If the meter reads zero volts until the light goes out and then reads 12 volts, you have isolated the correct wire and the wire's polarity is positive. finding a (+) parking light wire The (+) parking light wire is often found near the switch. Many cars have the switch built into the turn signal lever, and in these cars the parking light wire can be found in the steering column. The same wire is often available in the kick panel or running board.
■ At the dome light: This may not be your best choice if the vehicle has delayed domelight supervision, but it will work in many Hondas, or any vehicle with completely diode-isolated pin switches. Once you have determined the wire color, the easiest place to connect to the wire is often at the kick panel, at the windshield pillar, or in the running board. When an easy location is not available, running a wire to the domelight itself is often the best solution.

primary harness (H1) wire connection guide H1/1 RED/WHITE channel 2, 200mA (-) output When the system receives the code controlling Channel 2, for longer than 1.5 seconds, the red/white wire will supply an output as long as the transmission continues. This is often used to operate a trunk/hatch release or other relay-driven function. IMPORTANT! Never use this wire to drive anything but a relay or a low-current input! The transistorized output can only supply 200 mA of current.
H1/5 BLACK (-) chassis ground connection Remove any paint and connect this wire to bare metal, preferably with a factory bolt rather than your own screw. (Screws tend to either strip or loosen with time.) We recommend grounding all your components, including the siren, to the same point in the vehicle. T DRAFTF A R D H1/6 VIOLET (+) door trigger input, zone 3 This wire is used in vehicles that have a positive (+) switched dome light circuit.
H1/8 GREEN (-) door trigger input, zone 3 Most vehicles use negative door trigger circuits. Connect the green wire to a wire which shows ground when any door is opened. In vehicles with factory delays on the domelight circuit, there is usually a wire that is unaffected by the delay circuitry. This wire will report Zone 3.
H1/11 WHITE (+/-) selectable light flash output As shipped, this wire should be connected to the (+) parking light wire. If the light flash polarity jumper under the sliding door is moved to the opposite position (see Internal Programming Jumper section of this guide), this wire supplies a (-) 200 mA output. This is suitable for driving (-) light control wires in Toyota, Lexus, BMW, some Mitsubishi, some Mazda, and other model cars.

(See Feature Descriptions section of this guide.
NOTE! A 1-amp diode must be installed in line on the factory wire between the wait-to-start indicator and the ECM. (See the following diagram for details.
H2/6 LIGHT GREEN/BLACK (-) factory disarm This wire sends a negative pulse every time the remote start is activated or the doors are unlocked. This can be used to pulse the disarm wire of the vehicle's factory anti-theft device. Use a relay to send a (-) or (+) pulse to the disarm wire as shown in the following diagrams.
NOTE: If the factory supplies two separate (+) 12V feeds to the ignition switch, connect one RED wire of the satellite to each feed at the switch. ORANGE (+) accessory output Connect this wire to the accessory wire in the vehicle which powers the climate control system. PINK (+) ignition output Connect this wire to the ignition wire in the vehicle. PINK/WHITE (+) second ignition output Connect this wire to the second ignition wire in the vehicle. (See Finding the Wires You Need section.
IMPORTANT! Always perform the Safety Check section of this installation guide to verify that the vehicle cannot be started in ANY drive gear and that the override switch is functioning properly.
Figure A Figure B H3/2 VIOLET/WHITE tachometer input This input provides the module with information about the engine's revolutions per minute (RPMs). It can be connected to the negative side of the coil in vehicles with conventional coils. In multi-coil and high energy ignition systems locating a proper signal may be more difficult. (See Finding the Wires You Need section of this guide.) Once connected, you must teach the system the tach signal.

to the mechanical switch and a purple wire from the mechanical switch to the starter itself. Remember, this is only a rule of thumb and is not intended as a substitute for proper testing. We suggest the following procedure to test for vehicles manufactured in this way. NOTE: You must complete the remote start system installation before doing the following test. Ensure that the remote start system is functioning normally. This includes connecting to the brake as a shut-down.
However, due to future manufacturer changes in vehicles, it is possible that this may not apply to all vehicles. In addition, color variations are possible from model to model; make sure to test the circuit carefully. Please call Directed Electronics Technical Support if you need assistance in making this interface. IMPORTANT! Once the interface is complete, attempt to remote start the vehicle with the door closed and the key in the ignition. The vehicle should not start.
bypassing GM vehicle anti-theft systems (VATS) Vehicles with the GM VATS (Pass Key) systems have a resistor embedded in the ignition key. If the VATS decoder module does not measure the proper resistance when the vehicle is started, the starter and fuel pump may be disabled for up to ten minutes. An optional "VATS pack" of resistors is available (p/n 652T). One of the resistors in the pack will match the resistor in the key.
1995 and newer vehicle anti-theft systems (immobilizers) 1995 and newer vehicle anti-theft systems (immobilizers) require a bypass module. The bypass module allows for easy interfacing, while still maintaining the OEM system’s integrity.
der will then send a unique code back to the transceiver for evaluation. If the code matches a valid code of the system, the vehicle will be allowed to start. Most of these transponder-based systems can be bypassed using p/n 555U. Some may require additional parts from the vehicle manufacturer. Consult you dealer for the applications.
shock sensor harness, 4-pin connector GREEN (-) multiplex input, zone 4 Inputs shorter than 0.8 seconds will trigger the Warn Away response, while inputs longer than 0.8 seconds will trigger full alarm sequence and report Zone Four. If installing an optional Directed Electronics dual stage sensor, connect to the green wire as shown below. The diagram below eliminates the need for diodes to isolate the sensors.
3. The LED will light constant when the tach signal is learned. 4. Release the Valet/Program switch. programming jumpers T DRAFTF A R D tach threshold on/off In most cases, this jumper can be left in the OFF position. Some new vehicles use less than 12 volts in their ignition systems. The unit may have trouble learning the tach signal in these vehicles. Changing the jumper to the ON setting changes the trigger threshold of the digital tach circuit so it will work properly with these vehicles.
NOTE: For parking light circuits that draw 10 amps or more, the internal jumper must be switched to a (-) light flash output. P/N 8617 or a standard automotive SPDT relay must be used on the H1/11 light flash output harness wire. ™ transmitter/receiver learn routine The system comes with one transmitter that is programmed to the antenna. The system can store up to 4 different transmitter codes in memory.

multi-level security arming Multi-Level Security Arming is a feature that allows the user to select which of the system's inputs or sensors will be active and which will be bypassed when the system is armed. (See Table of Zones section of this guide.) Multi-Level Security Arming can only be accessed from a standard configuration transmitter. Pressing the arm button of the standard configuration transmitter again within five seconds of arming the system will activate the Multi-Level Security feature.
system features learn routine The System Features Learn Routine dictates how the unit operates. It is possible to access and change any of the feature settings using the Valet/program switch. However, this process can be greatly simplified by using the Bitwriter®. Any of the settings can be changed and then assigned to one of up to four transmitters. This feature is called Owner Recognition. Each time that particular transmitter is used to disarm the system, the assigned feature settings will be recalled.
5. Program the Feature. While holding the Valet/Program switch, you can toggle the feature on and off using the remote transmitter. Pressing the button that arms the system will select the one chirp or default setting. Pressing the button that disarms the system (or the Channel Two button when in the single button arm/disarm configuration) will select the two chirp setting. Note: Some features have more than two possible settings. Pressing setting, pressing 6.
To exit the learn routine: The learn routine will be exited if any of the following occurs: 1. Close the open door. 2. Turn the ignition on. 3. There is no activity for longer than 15 seconds. 4.

feature descriptions The features of the system are described below. Features that have additional settings that can be selected only when programming with the Bitwriter® are indicated by the following icon: menu #1 - basic features 1-1 ACTIVE/PASSIVE ARMING: When active arming is selected, the system will only arm when the transmitter is used. When set to passive, the system will arm automatically 30 seconds after the last door is closed.
turned on, forced passive arming will ensure that the system will passively arm, even if a zone is left open or invalid. Forced passive arming occurs one hour after the ignition is turned off. 1-9 AUTOMATIC ENGINE DISABLE (AED) ON/OFF: AED is a full-time, passive starter disable that works independently of the security system. When turned on, the orange, ground-when-armed output (H1/1) will activate 30 seconds after the ignition is turned off.
2-2 NUISANCE PREVENTION® CIRCUITRY (NPC) ON/OFF: NPC stops repeated triggering of the same zone. If one zone is triggered three times in one hour, that zone is bypassed for one hour, starting from the time of the third trigger. During that hour, if the system sees a trigger on that zone again, the system resets the one hour timer. If one hour passes and the zone has not triggered again, the zone is activated and can trigger the system again.
pulse. 2-9 FACTORY ALARM DISARM WITH CHANNEL 2: In the default setting the factory alarm disarm output will disarm the factory alarm system any time the button(s) controlling Channel Two is pressed. 2-10 FACTORY ALARM DISARM—WITH UNLOCK, BEFORE UNLOCK, REMOTE START ONLY: In the default setting the factory alarm disarm output will disarm the factory alarm system any time the button(s) controlling Unlock is pressed.
2-17 CHANNEL 6 LINKING (NONE)/ARM, DISARM, REMOTE START: Refer to feature 2-13 for additional detail. menu #3 - remote start 3-1 ENGINE CHECKING ON/OFF: In the default setting the remote start will monitor either the vehicle's tach wire or voltage depending on the programming of feature 3-2. If programmed OFF the vehicle will crank for the programmed crank time (feature 3-5) and will not verify with tach or voltage that the car is running.
Note: 1 or 2 pulses on the WHITE/BLUE remote start activation input wire as well as the button of the remote control. 3-9 2nd IGNITION/ACCESSORY OUTPUT: This will allow the PINK/WHITE to be used as a 2nd ignition or an accessory. The default is 2nd ignition. 3-10 ACCESSORY STATE DURING WAIT-TO-START OFF/ON: This feature will allow the selection of the accessory output to be ON or OFF during wait-to-start.
Disarming and rearming the system does not reset NPC. The only way to reset NPC is for the 60 minutes to pass, without a trigger, or for the ignition to be turned on. This allows the system to be repeatedly triggered, disarmed and rearmed, and still allow NPC to bypass a faulty zone. When disarming the system, 5 chirps indicate NPC is activated. The LED will report the zone that has been bypassed. (See Diagnostics section of this guide.
3. The rear defogger output will no longer activate when the vehicle is remote started. NOTE: If the remote start is On the lights will turn off then flash 2-times before returning to their normal output and the defogger output, if active, will cease. To turn the rear defogger output ON: 1. Press & release the and and buttons of the remote control. 2. The parking lights will flash 3-times. 3. The rear defogger output will once again activate when the vehicle is remote started.

Activate the remote start system. ■ If the starter engages, immediately step on the brake to shut down the system.
Does the Status LED indicate that the trigger was caused by the shock sensor? (See Diagnostics section of this guide.) The shock sensor, if set to extreme sensitivity, may be detecting the door unlatching before the door switch sends its signal. Reducing the sensitivity can solve this problem. ■ The Valet/Program switch doesn't work. Is it plugged into the correct socket? See Plug-In LED and Valet/Program Switch section of this guide. ■ Status LED doesn't work.
may have to adjust the voltage threshold in programming. Voltage sense will not work on some vehicles. 3. Check diagnostics. Sometimes a shutdown will become active during cranking or just after cranking. ■ The vehicle starts, but the starter keeps running. 1. Is the system programmed for engine checking off or voltage sense? When programmed for either of these features, the engine cranks for the preprogrammed crank time regardless of how long it takes for the vehicle to actually start.
