first programming tach, the unit will flash the parking lights 7 times indicating tach has not been learned and stored.
If the tach rate is not properly programmed to the specific vehicle, the unit may not realize that the vehicle is running
in certain instances and could re-engage the starter motor.
The Remote Car Starter will learn the tach rate of most vehicles single ignition coils, multiple coil packs, and or single
injector. To learn tach;
1. Turn the ignition key to the ON position.
2. Press and release the program switch 3 times.
3. Immediately turn the ignition key OFF.
4. Hold the program switch ON, then start the vehicle using the ignition key.
5. When the unit senses the tach signal, the parking lights will begin to flash.
6. Release the program switch. The parking lights will turn on for 3 seconds to indicate that the tach signal is stored
and the unit is now out of the program mode.
3. Diagnostics:
1. Be sure that programmable feature number #6 is set to the "Diagnostics On" mode.
2. Press and hold the program switch on, then turn the ignition key to the "ON" position.
3. The lights will flash and the number of flashes will indicate the reason for shutdown on the last remote start attempt.
The indications are as follows.
1 Flash 5, 10, 15, or 20, minute run timer expired.
2 Flashes Low or No tach signal received.
3 Flashes Positive or Negative input shut down.
4 Flashes Control switch was moved to "Off" position.
5 Flashes RF Shutdown command received.
6 Flashes High RPM signal over speed shut down.
7 Flashes Tach has NOT learned.
Multi Coil Pack Adapter: (Optional)
The multi coil pack adapter, (P/N 136B1400), is designed for use with vehicles that do not respond to single coil tach
programming. Although the tach resolution of this circuit is designed to interface direct with most vehicles, there may
be an occasion where the following circuit may be required.
To use the adapter, the Green/Black wires must connect to the negative side of the ignition coil(s).
1. For vehicles utilizing independent coils per cylinder, connect the three Green/Black leads to alternate coils. To
achieve optimum performance the coil signals must be evenly distributed. This is accomplished by first mapping
out the firing order of the engine in groups of as indicated below. Draw a circle around any of the columns. The
Green/Black wires should be connected to the negative (-) terminal of the respective cylinder number which
appears in any of the circles.
2. For vehicles utilizing 2 cylinder firing per coil pack, connect Green/Black to the tach side of each coil pack. For 8
cylinder, four coil systems, connect to any of the three coils.
3. Connect the Yellow wire to a +12 volt ignition 1 source. This wire will have +12 volts with the ignition in the on and
start position and have 0 volts with the ignition in the off position.
4. Connect the Green wire to the tach input of the Audiovox remote start unit.
