warning! safety first The following safety warnings must be observed at all times: ■ Due to the complexity of this system, installation of this product must only be performed by an authorized DEI dealer. ■ When properly installed, this system can start the vehicle via a command signal from the remote control transmitter. Therefore, never operate the system in an area that does not have adequate ventilation.
installation points to remember Before beginning the installation: IMPORTANT! This product is designed for fuel-injected, automatic transmission vehicles only. Installing it in a standard transmission vehicle is dangerous and is contrary to its intended use. ■ Please read this entire installation guide before beginning the installation. The installation of this remote start system requires interfacing with many of the vehicle’s systems.
finding the wires you need IMPORTANT! Do not use a 12V test light or logic probe/computer safe test light to locate these wires! All testing described in this manual assumes the use of a digital multimeter. obtaining constant 12V We recommend two possible sources for 12V constant: The (+) terminal of the battery, or the constant 12V supply to the ignition switch. Always install a fuse within 12 inches of this connection.
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. If the starter does not turn over, you have the right wire. 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).
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. If the meter shows (+)12V, turn off the parking lights and make sure it returns to zero. 5.
finding the wait-to-start bulb wire for diesels In diesel vehicles it is necessary to interface with the wire that turns on the WAIT TO START light in the dashboard. This wire illuminates the bulb until the vehicle’s glow plugs are properly heated. When the light goes out the vehicle can be started. This wire is always available at the connector leading to the bulb in the dashboard. It can also be found at the Engine Control Module (ECM) in many vehicles. To test and determine the polarity of this wire: 1.

to a keyless entry system. This wire can also be connected to an optional momentary switch to activate the remote start system. H1/3 LIGHT GREEN/BLACK (-) factory security disarm/special accessory output This wire sends a negative pulse every time the remote start is activated. 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.
H1/5 WHITE (-) light flash output This wire provides a (-) 200mA output to flash the parking lights during remote start operation. This is suitable for driving (-) light control wires in Toyota, Lexus, BMW, some Mitsubishi, some Mazda models, etc. If the vehicle has a positive parking light circuit a relay must be used to flash the parking lights.

relay satellite key switch interface The heavy gauge wires leading from the relay satellite are used to energize high current circuits in the vehicle. It is crucial that these connections are made correctly so that they are capable of handling the current demands. For this reason, scotch locks, T-taps and other such connectors should not be used.
remote start harness (H2), 6-pin connector H2/1 BLUE status/factory security rearm output This output is programmable. If programmed for status output, the wire will supply an output at all times the remote start is operating. If programmed for factory security rearm, the wire will supply a pulse whenever the remote start times out or is shut down using the transmitter. H2/2 BLUE/BLACK (-) third ignition output This output provides 200mA as soon as the remote starter is activated.
H2/6 BLACK/WHITE neutral safety switch input Connect this wire to the toggle (override) switch as shown in Figure A. Connect the other wire from the toggle switch to the PARK/NEUTRAL switch in the vehicle. This wire will test with ground with the gear selector either in PARK or NEUTRAL. This will prevent the vehicle from accidentally being started while in a drive gear. This input MUST rest at ground in order for the remote start system to operate.
Vehicles with the neutral safety switch built into the column shifter require that the shifter be placed in park in order to remove the keys from the ignition. As a result, it is possible to use the key-in-ignition sense switch to prevent remote starting if the keys are in the ignition. (See General Motors Trucks, SUVs and Column-Shifting Passenger Cars and Pre-1996 Dodge Dakota Pickups with 2.5 Liter Motors diagrams in this section on how to accomplish this.

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 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.
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. For most Ford PATS transponders, p/n 555F can be used, except for the following vehicles, which will require p/n 555U: ‘97 and newer Mark VII, and 2000 and newer Taurus/Sable, Contour/Mystique and Focus.
plug-in program switch The Program switch plugs into the blue two-pin connector. tach learning To learn the tach signal: 1. Start the vehicle with the key. 2. Within 5 seconds, press and HOLD the Program switch. 3. The LED will light constant when the tach signal is learned. If the LED does not light bright DRW-96 red, the unit did not learn the tach signal. (Refer to Finding the Tachometer Wire in the Finding the Wires You Need section of this guide.) 4. Release the Program switch.
internal programming jumper digital tach threshold on/off Remove the control module case cover to access the jumper. 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.
operating settings 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 Program switch. The programmable operating settings of this unit can be changed whenever necessary through the computerbased Learn Routine. The Program push-button switch, plugged into the blue port, is used together with a programmed transmitter to change the settings. To program settings, remember: Key, Choose, Transmit and Release.
The learn routine will be exited if: ■ The ignition is turned on. ■ The Program switch is pressed too many times. ■ More than 25 seconds elapses between programming steps. features menu The factory default settings are indicated below in bold.
2 TACH WIRE SENSE/VOLTAGE SENSE: If the tachometer signal wire is used, this feature must be left in the default (tach wire connected) setting. If programmed to the voltage sense setting, the unit will crank the starter for a preset time that can be programmed in Feature 5. Once the starter has been engaged, the system will check the voltage level to verify the engine is running. The threshold for the voltage level test can be programmed in Feature 6.
shutdown diagnostics The unit has the ability to report the cause of the last shutdown of the remote start system. To enter diagnostics mode: 1. Turn the ignition off. 2. Press and hold the Program switch. 3. Turn the ignition on and then off. 4. Release the Program switch. 5. Press and release the Program switch.
timer mode This unit can be programmed to start and run the engine every three hours. The engine will run for the programmed run time and then shut down. After three hours, the unit will restart the engine. A maximum of six cycles can occur. IMPORTANT! Timer Mode should be used only in open areas. Never start and run the vehicle in an enclosed space such as a garage or carport. To enter Timer Mode: 1. Turn the ignition on. 2. Press and HOLD the auxiliary channel transmitter button controlling remote start.
a. Make sure the hood is closed and no other shutdown circuits are active. b. Set the emergency brake. c. Turn the ignition key to the run position but do not start the engine. d. Put the vehicle in Drive (D). e. Put your foot over the brake pedal but do not press down on it. Be ready to step on the brake to shutdown the remote start system. f. Activate the remote start system. ■ If the starter engages, immediately step on the brake to shut down the system.
■ The vehicle starts, but immediately dies. 1. Does the vehicle have an immobilizer? The vehicle’s immobilizer will cut the fuel and/or spark during unauthorized starting attempts. 2. Is the remote start programmed for voltage sense? If so, the start time may not be set high enough, or you 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.
