Tach Learning
Tach jumper settings
Some new vehicles have a higher
TACH voltage threshold, which
would fall out of the normal TACH
trigger circuit of the remote car
starter. Changing the jumper to
TACH Threshold HIGH will allow
the module to properly detect the
TACH signal.
Multi­speed Tach Programming Procedure
The system is designed to read a wide range of Tach signals produced by newer Ignition
systems. Note that you should go through the Tach programming procedure every time a new
Unit is installed.
Enter programming mode (page-17) ⎯ the parking lights will stay on for up to 20
1.
seconds.
2. Before the lights go out, press and hold the brake pedal and press the
buttons simultaneously ⎯ the siren will chirp 4 times.
3. Release the brake pedal.
4. Start up the engine and allow the vehicle to reach regular engine idle speed.
5. Once the engine is running at normal idle speed, press the brake pedal and keep it
down until you hear the siren chirps 2 times.
Release the brake pedal ⎯the tach programming is now complete.
6.
Note: If another Tach programming is required, simply repeat the "Multi Speed Tach
learning".
Auto Tach Programming Procedure
This process can be carried out instead of the conventional Tach Programming Procedure.
1. Make sure all the connections are done properly and that the Module has been
powered-up.
2. With the Hood up (Ground on the Hood Pin line), start the vehicle using the key.
3. Start up the engine and allow the vehicle to reach regular engine idle speed.
4. Once the engine is running at normal idle speed, press the brake pedal and keep it
down until you hear the siren chirps 2 times.
5. Turn the Ignition OFF. At this point, the Tach setting has been programmed.
Note: The "Auto tach programming" can only be carried out once unless the system is reset.
Siren/Horn Timing Adjustment
Follow these steps to adjust siren/horn pulse timing:
1) Enter programming mode (page-17) - the parking lights will stay on for up to 20
seconds.
2) Press and hold the brake pedal, then simultaneously press the
⎯ the siren will chirp 5 times.
