Tachometer Programming
After making all your connections to both the PKE & PBS modules, the final step
is to program the system to learn your vehicles tachometer signal. This is
necessary so that the systems Remote Start & One Touch Starting functions
can determine when you vehicles engine is running. The Tach wire on the PBS
tells the Module if the Engine is running or not. It requires at least 3 volts (AC)
and 20 Hz (or faster) at idle. Note: Be sure that the Yellow PBS Tachometer
signal wire is hooked to a good source.
The best Tach references are:
the negative side of an injector, or the negative
side of an Ignition Coil, or the Engine Control Module (ECM).
(Note: we do not
recommend using the ach reference wire from a data module as these often do
not give an adequate signal)
*** Prior to programming your vehicles Tach signal
it is critical that you have
first made the proper Interface connections to with the vehicles Neutral Safety
Switch. Shown below
Tech Programming Procedure
With the PSB in OFF status, enter the vehicle with your iKey. The LED on the
Start button will come on Amber.
To enter the system into Tach Learning Mode:
Press and HOLD the Start Button down.
Next, Press the Brake Pedal five (5) times quickly.
After the 5
th
push of the Brake pedal, keep the pedal fully depressed.
Next, release the Start Button and continue to hold the Brake pedal down.
The LED on the Start Button (Lexus Button) will alternately flash Green and Red
as the system enters Tach Learning Mode. You will now have 25 seconds to
start your engine to allow the PBS to learn the vehicles Tach signal.
Next, Push the Start Button and crank the Engine, release it when the Engine is
started. Allow the engine to warm up enough to obtain a typical idle RPM. (At
least 30 seconds but a maximum of 2 minutes) then release the Brake Pedal.
Your engine will keep running if programming was successfully, or shutdown
immediately if the system failed to learn your Tach signal. * If the system does
not learn your Tach signal on the first attempt, try a couple more times. If it is
still unsuccessful, you change the Yellow Tach sense wire to a different Tach
reference location.
