Diagnostics; Multi Coil Pack Adaptor - Audiovox Car Security System AX-900 Installation Manual

NOTE: If the unit fails to learn tach rate due to an improper tachometer connection or a poor tach source, the
parking lights will not flash.
To correct this situation, locate and connect the Purple/White wire to the proper tach signal, and then repeat the tach
learn routine.

Diagnostics:

Enter selectable feature #7 and turn on as described above.
NOTE: Diagnostic mode is a temporary mode. Once you have accessed the diagnostic mode, the unit will pause
for two seconds then begin to flash the last stored shut down code. This code will be displayed three times in
succession, then the unit will automatically exit the diagnostic on mode.
The parking lights will flash a number of times indicating the reason for the last remote start shutdown. The light
flash indications are as follows:
1 Flash Run timer expired
2 Flashes Low or no tach signal (RPM)
3 Flashes Positive or Negative inhibit wire activation
4 Flashes Control switch moved to the off position
5 Flashes RF shutdown, Remote signal received, or manual start trigger wire reactivated.
6 Flashes High tach signal (RPM)
7 Flashes Tach signal has not been learned
Multi Coil Pack Adaptor: (Optional)
The multi coil pack adaptor is designed for use with vehicles having multiple ignition coils where a single point tach
signal is unavailable, or non responsive. P/N 136B1400
To use the adaptor, 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 map-
ping 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 (Green), (Orange/Green), or (Purple/White) tach input of the Audiovox remote start
unit.
