REMOTE START NOTES Smart Start and Tach Start In order for the system to properly start and run the vehicle, the unit must be able to determine if the engine is cranking or if the engine is actually running. This system is equipped with two means of detecting the engine's run status: Smart Start and Tach Start. The Smart Start feature detects the engine's run status using specially designed software that interprets certain characteristics of the engine, without connection to the vehicle's tachometer wire.This feature allows a faster installation, but may not be compatible with all vehicles, or under extreme temperatures. The Tach Start feature requires connection the the vehicle's tachometer wire, or an injector wire if the tach wire is not available. The Tach Start provides reliable operation with virtually any vehicle, even under extreme temperatures. Tach Wire Locator To aid in the locating and testing of a suitable tach wire, the start module is equipped with a LED that flashes to indicate presence of a RPM signal. To use this tach locator, set dip switch #6 to On and be sure dip switch #2 is set for RPM (Off). With the engine running, probe the suspected tach wire with the Gray/Black wire (tach input). The LED will begin flashing if the Gray/Black wire is reading a proper tach signal. If the LED does not flash, continue testing suspected tach wires until the correct wire is found. After the proper tach wire is located and all start module connections have been made, test the remote start by pressing the engine start button on the module located next to the RPM signal LED. If the engine starts and runs properly, press the button again to stop the engine. Gas and Diesel Modes The default setting for the engine mode is Gas Engine. For diesel vehicles, the engine type for dip switch #5 must be set to Diesel Engine. When programmed for diesel engines, the Orange/Violet wire (glow plug input) is monitored to make sure the glow plugs have warmed up before the engine begins cranking. If the glow plug wire is not connected, the unit has a built-in timer that waits 10 seconds before cranking the starter. BYPASSING FACTORY THEFT DETERRENT SYSTEMS Many newer vehicles are now factory-equipped with anti-theft systems that use either a resistor coded key or a passive transponder that disables the fuel system unless a properly coded key is inserted into the ignition cylinder. To integrate a remote starter into these vehicles, you must determine which type of factory anti-theft system is equipped, then use the proper bypass module for that system. General Motors Anti-theft Systems: Many late-model GM vehicles are equipped with one of three basic anti-theft systems; Passkey, Passlock, and Passkey 3. Standard Passkey systems are easily identified by the resistor chip visible on the shaft of the key. Passlock systems do not rely on a resistor equipped key. Instead they use a resistance code generated when the key is turned in the ignition cylinder. Both of these systems have an anti-theft indicator in the instrument cluster. To properly interface into these systems and retain full functionality of the factory anti-theft system, VATS/PASSLOCK bypass module must be installed. The Passkey 3 system, which is found on GM vehicles 1999 and newer, is a transponder based system described below. 19
