After the remote start module has been installed, test the remote start module in accor- ■ dance 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.
after the installation ■ Test all functions. The “Using Your System” section of the Owner's Guide is very helpful when testing. ■ When testing, don’t forget that this system is equipped with Nuisance Prevention® Circuitry (NPC). NPC can bypass trigger zones, making them appear to stop working. See the Nuisance Prevention® Circuitry section. ■ Review and complete the Safety Check section of this guide prior to the vehicle reassembly.
locations for the control module Some things to remember about where to mount the control module: ■ Never put the control module in the engine compartment! ■ The first step in hot-wiring a vehicle is removing the driver's side under-dash panel to access the starter and ignition wires. If the control module is placed just behind the driver's side dash it can easily be disconnected.
vertically but range will be diminished. Metallic window tint can also affect range, so this should be a consideration when determining the mounting location. After determining the best mounting location, follow these steps: 1. Clean the mounting area with a quality glass cleaner or alcohol to remove any dirt or residue. 2. Mount the antenna using the supplied double-sided tape. 3. Route the antenna cable to the control module and plug it into the antenna connector.
This system has Remote Valet. The user can enter and exit Valet Mode without having to reach the Valet/ Program switch. This feature was introduced so that switch location was less critical in day-to-day use. As long as the Valet/Program switch can be reached to disarm without a remote control, easy access is not important. locations for the status LED Things to remember when positioning the Status LED: ■ It should be visible from both sides and the rear of the vehicle, if possible.
locations for the relay satellite The relay satellite wiring carries large amounts of current. The wires should not be extended and should be cut to the minimum length necessary. Since the relay satellite is functioning as the ignition switch in the vehicle, it is often convenient to mount the relay satellite close to the main ignition switch harness.
fuse, of the proper value, regardless of how many accessories are added to the main power feed. 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. Attach the (-) probe of the meter to chassis ground. 3. Probe the wire you suspect of being the ignition wire. The steering column harness or ignition switch harness is an excellent place to find this wire. 4. Turn the ignition key switch to the run position. If your meter reads (+)12V, go to the next step. If it doesn’t, probe another wire. 5. Now turn the key to the start position.
this wire. Remember you do not need to interrupt the starter at the same point you test it. Hiding your optional starter kill relay and connections is always recommended. 4. Turn the ignition key switch to the start position. Make sure the car is not in gear! If your meter reads (+)12V, go to the next step. If it doesn’t, probe another wire. 5. Cut the wire you suspect of being the starter wire. 6. Attempt to start the car. If the starter engages, reconnect it and go back to Step 3.
transmission computers. IMPORTANT! Do not test tachometer wires using a test light or logic probe (computer safe test light)! This will damage the vehicle. How to find a tachometer wire with your multimeter: 1. Set to ACV or AC voltage (12V or 20V is fine). 2. Attach the (-) probe of the meter to chassis ground. 3. Start and run the vehicle. 4. Probe the wire you suspect of being the tachometer wire with the red probe of the meter. 5.
Remember, you need a (+) parking light wire that does not vary with the dimmer setting. How to find a (+) parking light flash wire with your multimeter: 1. Set to DCV or DC voltage (12V or 20V is fine). 2. Attach the (-) probe of the meter to chassis ground. 3. Probe the wire you suspect of being the parking light wire. Usually, the area near the headlight/parking light switch is an excellent area to start, as is the kick panel. 4. Turn on the parking lights.
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. How to find a door pin switch trigger wire with your multimeter: 1. Set to DCV or DC voltage (12V or 20V is fine). 2.

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. H1/6 VIOLET (+) door trigger input, zone 3 This wire is used in vehicles that have a positive (+) switched dome light circuit.
H1/7 BLUE (-) 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 the full alarm sequence. If installing an optional Directed Electronics dual stage sensor, connect both the blue and the green wires of the optional sensor to this input. This wire will report Zone 4. H1/8 GREEN (-) door trigger input, zone 3 Most vehicles use negative door trigger circuits.
H1/10 WHITE/BLUE remote start (-) activation input This input comes from the factory set to 2 activation pulses. This means that it is necessary to have 2 consecutive ground pulses on the white/blue wire for the remote start to activate or to deactivate. The same holds true for the remote control activation when set to a two pulse setting it is necessary to press the button twice for the remote start to activate or deactivate. NOTE: The number of activation inputs can be programmed to 1 or 2 pulses.
Lexus, BMW, some Mitsubishi, some Mazda, and other model cars. (+) Positive Light Flash Output (-) Light Flash Output NOTE: For parking light circuits that draw 10 amps or more, the internal jumper must be switched to a (-) light flash output. (See the Internal Programming Jumper section of this guide.) P/N 8617 or a standard automotive SPDT relay must be used on the H1/2 light flash output harness wire.
H1/12 ORANGE (-) ground-when-armed output This wire supplies a (-)500 mA ground as long as the system is armed. This output ceases as soon as the system is disarmed. The GWA can be hooked up to a window control module, a voice module or any accessory that requires a ground when armed. secondary harness (H2) wire connection guide H2/1 LIGHT BLUE (-) 200mA 2nd unlock output This wire provides a second unlock output for progressive locks.
H2/4 GREEN/WHITE (-) factory alarm rearm This wire sends a negative pulse every time the remote start shuts down or the doors are locked. This can be used to pulse the arm wire of the vehicle's factory anti-theft device. Use a relay to send a (-) or (+) pulse to the arm wire. H2/5 GRAY/BLACK (-) diesel wait-to-start bulb input Connect this wire to the wire in the vehicle that sends the signal to turn on the WAIT-TO-START bulb in the dashboard.
H2/6 LIGHT GREEN/BLACK (-) factory disarm This wire sends a negative pulse every time the remote start is activated , channel 2 is activated (programmable on/off) or when the doors are unlocked with the remote. 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.
relay satellite wire connection guide The 8 heavy gauge wires coming from the large connector are used to energize high current circuits in the vehicle. It is crucial that these connections are well-made and capable of handling the current demands. For this reason, Scotch-Locks, T-taps and other such connectors are strongly discouraged. PURPLE (+) starter output Connect this wire to the starter wire in the vehicle. (See Finding the Wires You Need section.
PINK/WHITE (+) second ignition output Connect this wire to the second ignition wire in the vehicle. (See Finding the Wires You Need section.) NOTE: For vehicles that do not have a second ignition wire, this connection is not required. RED/WHITE (+) 12V input Connection for high current outputs.

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 a fuel injector or 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.

GM vehicles that have the neutral safety switch built into the column shifter can usually be identified by a purple starter wire. Typically, vehicles that use an outboard mechanical switch use a yellow wire from the ignition switch 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.
by pressing the brake without the key sense wire shutting down the unit prematurely. In addition, you must connect a tan (+) shut-down input to the yellow wire on the relay satellite ribbon cable. This prevents the remote start system from activating if the key is left in the "run" position. If your remote start system only has one tan input, you must use diodes to isolate the ignition circuit from the brake switch input.
Vehicle immobilizer or key cylinder systems Most new vehicles have a factory engine immobilizer system designed to prevent any unauthorized use of the vehicle. These immobilizers will cut off power to the starter and the fuel supply preventing a thief from starting the vehicle. Some are basic resistance-based systems that require a correct value resistor embedded in the key to start the vehicle.
plug-in LED and valet/program switch These plug into the module. The Status LED plugs into the white two-pin socket, while the Valet/Program 9 Switch should be plugged into the blue two-pin connector. The Status LED fits into a /32-inch hole.
programmer interface, 3-pin black plug The black 3 pin port is provided for programming the unit using the Bitwriter (p/n 998T). When using the Bitwriter, it is possible to configure any and all of the programmable functions as well as lock the Remote Control and System Features Learn Routines so that unauthorized users cannot change the configuration or program remote controls to the unit. When the learn routines have previously been programmed using the Bitwriter, they may have been locked.
BLUE (-) multiplex input, zone 2 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 will also report Zone Two. RED and BLACK: RED is (+)12V constant, BLACK is (-) ground Do not use these for anything besides the plug-in shock sensor. tach learning To learn the tach signal: 1. Start the vehicle with the key. 2. Within 5 seconds, press and hold the Valet/Program switch. 3.
programming jumpers 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. These vehicles include many newer Dodge/Chrysler/Plymouths, such as the Neon Cirrus/Stratus/Breeze and LH-based cars.
remote control learn routine™ The system comes with one remote control that is programmed to the antenna. The system can store up to 4 different remote control codes in memory. Use the following learn routine to add remote controls to the system or to change button assignments if desired. The learn routine may be locked if previously programmed using the Bitwriter®.

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 remote control is used. When set to passive, the system will arm automatically 30 seconds after the last door is closed.
Ford vehicles. 1-8 FORCED PASSIVE ARMING ON/OFF: To use this feature, passive arming must be selected in Feature 1-1. When 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.
sound. When using the Bitwriter®, the siren can be programmed to sound for any length of time from 1 second to 180 seconds. 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.
extra parts for unlock and lock outputs (see below). 2-8 LOCK OUTPUT—1, 2 PULSES: This will program the lock output to one or two pulses. When the double pulse lock feature is turned on, the BLUE door lock harness wire will supply two positive pulses instead of a single pulse. At the same time, the GREEN door lock harness wire will supply two negative pulses instead of a single pulse.
Channel Five can be programmed for these output configurations. The unit is set to the default validity output. To change the configuration, use the two-chirp setting to toggle through the different configurations.

long term event history The system stores the last two full triggers in memory. These are not erasable. Each time the unit sees a full trigger, the older of the two triggers in memory will be replaced by the new trigger. To access long term event history: 1. With the ignition off, press and hold the Valet/Program switch. 2. Turn on the ignition. 3. Release the Valet/Program switch. 4. Press and release the Valet/Program switch within 5 seconds.
safety check Before vehicle reassembly, the remote system must be checked to ensure safe and trouble-free operation. The following test procedure must be used to verify proper installation and operation of the system. The installation must be completed before testing, including connection to the brake switch and hood switch. 1. Test the BRAKE shutdown circuit: With the vehicle in Park (P), activate the remote start system. Once the engine is running, press the brake pedal.
troubleshooting alarm troubleshooting ■ Shock sensor doesn't trigger the alarm: Has the NPC® system been triggered? If so, you will hear 5 chirps when disarming. To check this, turn the ignition key on and off to clear the NPC®'s memory, and then retest the shock sensor. For a detailed description of NPC®, see Nuisance Prevention Circuitry section of this guide. ■ Door input does not immediately trigger full alarm.
remote start troubleshooting ■ The remote start will not activate. 1. Check the harnesses and their connections. Make sure that the harnesses are completely plugged into the remote start module. Make sure there are good connections to the vehicle wiring. 2. Check voltage and fuses. Use a meter to check for voltage between the red wire in the 5-pin ribbon harness and the black ground wire. If you have less than battery voltage, check the 3A and both 30A fuses on the relay satellite.
■ 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. Adjust to a lower cranking time. 2. Was the Tach Learn successful? The LED must light solid and bright to indicate a successful learn. 3.
