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.
Important:
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 fine tune
the starter output time in 50mS increments to compensate for such an occurrence.
Learning the Tach (not needed with Virtual Tach)
To learn the tach signal:
1.
Start
the vehicle with the key. Within 5 seconds,
press
and
hold
the Control button.
2. After 3 seconds the status LED on your Control Center lights constant when the tach signal is learned.
3.
Release
the Control button.
Note:
When the tachometer is programmed the main unit automatically enters the Tachometer engine check-
ing mode.
Since this unit has the capability to learn the tachometer with the analog input or through D2D from an
interface module, the unit gives confirmation as to which source the unit has learned from. After learning the
tach and releasing the Control button, the system:
Flashes the parking lights once if programmed using the analog tach wire.
Flashes the parking lights twice if programmed using the interface module through D2D.
Neutral safety switch interface
Some vehicles do not have an electrical neutral safety switch. Instead, the vehicle has a mechanical neutral
safety switch that physically interrupts the starter wire and is used when the vehicle is in any drive gear. If the
remote start is interfaced before this switch, it will provide protection from starting in gear. However, some
vehicles combine the column shift mechanism and the mechanical neutral safety switch into one mechanical
part.
Important:
You must complete the remote start system installation before doing the follow-
ing test. Ensure that the remote start system is functioning normally. This includes connect-
ing to the brake as a shut-down.
Testing the neutral safety switch
1. Make sure there is adequate clearance to the front and rear of the vehicle because it may move slightly.
2. Make sure the hood is closed and there are no remote start shut-downs active.
3. Set the emergency brake.
4. Turn the key to the “run” position, this releases the shifter.
5. Place the car in drive (D).
6. Place your foot directly over the brake pedal, but do not depress it. Be ready to step on the brake if the
starter engages.
7. Activate the remote start system.
8. If the starter engages, immediately depress the brake to shut the remote start system down. If the
starter does not engage, no additional safety
system is required.
If the starter engages and the vehicle is a General Motors product or Dodge Dakota pickup, refer to
www.
directechs.com
for Document 1008 under the Resource tab. For an alternative shut-down method
which prevents the starter from engaging. If the vehicle is not a General Motors product or a Dodge
Dakota pickup, please call Directed Electronics Technical Support for an alternative shut-down method.
Do not return the vehicle to the customer until this feature is properly installed!
