* This optional input can be connected to the horn circuit (+ or -). When this wire receives input for a minimum of.5 seconds, the system reports a trigger on the 2-way remote. This is useful on vehicles that have a factory security system that can be armed/disarmed with the Directed system. This system will not report that a zone has been triggered when unlocking with the 2-way remote. This feature is not available on the 1-way remote.

Installation Points

Learning the Tach (not needed with Virtual Tach)

To learn the tach signal:

1. Start the vehicle with the key.
2. Within 5 seconds, press and hold the Control button.
3. After 3 seconds the status LED on your Control Center lights constant when the tach signal is learned.
4. Release the Control button.

Learning Virtual Tach (not needed with hardwire tach inputs)

To program Virtual Tach:

1. After the install is complete, remote start the engine. The programming operation may require 3 cranks of the starter before the engine starts and runs. Do not turn off the remote start if this happens, it is a normal programming operation.
2. Once the engine begins running, let it run for at least 30 seconds.
3. Using the Remote, send the Remote start command to turn remote start off. Virtual Tach is programmed.

To reset Virtual Tach, go into the Remote Pairing section of this guide and press/release the Control button 4 times for step #4, then press and hold the Control button to reset Virtual Tach. Virtual Tach cannot be reset with the Bitwriter.

Note: Virtual Tach cannot be used in MTS Manual Transmission Mode. It is also not recommended for diesel trucks.

Virtual Tach handles disengaging the starter motor during remote starting – it does not address over-rev. If the customer wants to have the over-rev protection capability, the tach wire must be connected.

After successfully learning Virtual Tach, a small minority of vehicle starters may over crank or under crank during remote start. The Bitwriter can be used to fine tune the starter output time in 50mS increments to compensate for such an occurrence.

Remote Start Shutdown/Startup Diagnostics

To perform shutdown diagnostics:

1. With the ignition Off, press and hold the Control button.
2. Turn the ignition On and then back Off while holding the Control button.
3. Release the Control button.
4. Press and release the Control button. The status LED flashes to report the last shutdown for one minute or until the ignition is turned on, as shown in the following table:

* Timer mode error: Ignition is on or shutdown input is active when activating timer mode.
Turbo mode error: Turbo mode is programmed off, engine is not on or shutdown input is active.
Manual mode error: MTS mode not enabled.

Startup Diagnostics: If the vehicle fails to activate the remote start, the remote start module will flash the parking lights on the vehicle to notify you of what caused the no-start situation.
