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 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. Before beginning the installation: ■ 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 your meter shows (+)12V, turn off the parking lights and make sure it goes back 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.

primary harness (H1), 8-pin connector H1/1 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 to the same point in the vehicle. H1/2 WHITE/BLUE (-) activation input Sending a negative pulse to this wire will initiate the remote start sequence.
Relay for Negative (-) Disarm Wire Relay for Positive (+) Disarm Wire H1/4 YELLOW (+) ignition output to RF system As a stand-alone system: The H1/4 YELLOW wire should not be connected to anything. As an add-on car starter: If connected, disconnect the ignition/accessory input of the remote controlled security or keyless entry system. Connect the H1/4 YELLOW ignition output to the ignition/accessory input of the remote controlled security or keyless entry system.
(-) Light Flash Output H1/6 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. In most diesels the wire is negative (ground turns on the bulb) and the GRAY/BLACK can be directly connected to the wire in the vehicle. If the vehicle uses a positive wire (12V to turn on the bulb) a relay must be used to change the polarity. (See Finding the Wires You Need section for testing procedures.
H1/7 LIGHT GREEN (-) door lock output This wire provides a negative output to lock the vehicle's doors. To interface this output with the vehicle's power door lock system, see the Door Lock Wiring Guide section of this guide. H1/8 LIGHT BLUE (-) door unlock output This wire provides a negative output to unlock the vehicle's doors. To interface this output with the vehicle's power door lock system, see the Door Lock Wiring Guide section of this guide.
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 a 200 mA ground output at all times the remote start is operating. If programmed for factory security rearm, the wire will supply a 200 mA ground pulse whenever the remote start times out or is shut down using the transmitter.
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. The system includes a "VATS pack" of resistors. One will match the resistor in the key. The VATS wires will be two very light-gauge wires coming out of the steering column.
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.
will excite the transponder, which is located (but not visible) in the head of the ignition key. The key transponder 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.
door lock wiring guide The blue (H1/8) and green (H1/7) lock wires provide 200mA negative pulses that are used to control electric door locks. Most common interfaces are described in this section. type A: (+) 12V pulses from the switch to the factory relays The correct wires can usually be found in either kick panel. If you cannot get to the switch, and you find a set of wires that pulse (+)12V alternately on lock and unlock, you must take care to ensure that it is not a Type C direct-wire system.
type B: (-) pulses from the switch to the factory relays This system is common in many Toyotas, Nissans, Hondas, and Saturns, as well as Ford models with keyless entry systems (some other Fords also use Type B). The switch will have three wires on it, and one wire will test ground all the time. One wire will pulse (-) when the switch locks the doors, and the other wire will pulse (-) when the switch unlocks the doors. This type of system is difficult to mistake for any other type.
type C: reversing polarity Interfacing with a reversing polarity system requires either two relays or one 451M (not included). It is critical to identify the proper wires and locate the master switch to interface properly. Locate wires that show voltage on lock and unlock. Cut one of the suspect wires and check operation of the locks from both switches. If one switch loses operation in both directions and the other switch operates in one direction only, you have located one of the target wires.
type D: after-market actuators In order for this system to control one or more aftermarket actuators, a 451M or two relays (optional) are needed. Vehicles without factory power door locks require the installation of one actuator per door. This requires mounting the door lock actuator inside the door. Other vehicles may only require one actuator installed in the driver's door if all door locks are operated when the driver's lock is used.
type E: mercedes-benz and audi (1985 & newer) This type of door locking system is controlled by an electrically activated vacuum pump; however, the 551R is not capable of controlling Type E locks. type F: one-wire system This system usually requires a negative pulse to unlock, and cutting the wire to lock the door. In some vehicles, these are reversed. This system is found in late-model Nissan Sentras, some Nissan 240SX, and Nissan 300ZX 1992 and later.
type G: positive (+) multiplex This system is most commonly found in Ford, Mazda, Chrysler and GM vehicles. The door lock switch or door key cylinder may contain either one or two resistors. When interfacing with this type of door lock system, two relays or a DEI 451M must be used. (See diagram below.) single-resistor type If one resistor is used in the door lock switch/key cylinder, the wire will pulse (+)12V in one direction and less than (+)12V when operated in the opposite direction.
type H: negative (-) multiplex The system is most commonly found in Ford, Mazda, Chrysler and GM vehicles. The door lock switch or door key cylinder may contain either one or two resistors. single-resistor type If one resistor is used in the door lock switch/key cylinder, the wire will pulse ground in one direction and resistance to ground when operated in the opposite direction.
internal programming jumper digital 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.
plug-in program switch The Program switch plugs into the blue two-pin connector. transmitter/receiver learn routine The system comes with one transmitter that has been taught to the receiver. The receiver can store up to 4 different transmitter codes in memory. Use the following learn routine to add transmitters to the system or to change button assignments if desired. The Program switch, plugged into the blue port, is used for programming.
3. Transmit. While HOLDING the Program switch, press the button on the transmitter that you would like to control the selected receiver channel. 4. Release. Once the code is learned, the Program switch can be released. You can advance from programming one channel to another by releasing the Program switch and tapping it to advance steps and then holding it. For instance: You have programmed Channel One and you want to program Channel Two. Release the Program switch.
operating settings learn routine The System Features Learn Routine dictates how the unit operates. The programmable operating settings of this unit can be changed whenever necessary through the computer-based Learn Routine. The Program push-button switch, plugged into the blue port, is used together with a programmed transmitter to change the settings. It is possible to access and change any of the feature settings using the Program switch. To program settings, remember: Key, Choose, Transmit and Release.

3 RUN TIME 12/24/60 MINUTES: This feature controls how long the engine will run before it “times out” and shuts down. Programmed to the default setting the engine will run for 12 minutes. If the 24 or 60 minute run time is desired, change this feature to the two or three flash setting. 4 PARKING LIGHTS FLASHING/CONSTANT: In the default setting, the unit will flash the vehicle’s parking lights while remote started. The constant setting will turn the parking lights on solidly for the entire run duration.
shutdown diagnostics The unit has the ability to report the cause of the last shutdown of the remote start system. To enter diagnostic 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. The same procedure may be used to enter or exit Timer Mode using the remote transmitter: 1. Remote start the vehicle. 2.
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 ■ The ignition comes on, but the starter will not crank. Does it start with the key in the ignition? If so, does the vehicle have a VATS Pass-Key system? Will it start with the brake pedal depressed? (Make sure to disconnect the brake shutdown when performing this test.) If so, it may have a brake/starter interlock. Is the correct starter wire being energized? Check by energizing it yourself with a fused test lead. ■ The starter cranks for six seconds but does not start.
5. Does the vehicle have an immobilizer? Some immobilizer systems will not allow the vehicle to crank if active. 6. Check connections. The two red heavy gauge input wires on the relay satellite should have solid connections. "T-taps", or "scotch locks" are not recommended for any high current heavy gauge wiring. Also, if the vehicle has more than one 12-volt input wire, then connect one red wire to each. ■ The vehicle starts, but immediately dies. 1.
