Monitoring The Vehicle's Engine (Voltage Tach, Dbi, Hybrid,); Tach Programming; Diagnostics Access & Information - Prestige APS-787E Installation Manual

Monitoring The Vehicle's Engine:
There are 4 ways that the remote start monitors the engine running, one or the other must be selected
for your application for the remote start to operate correctly.
1) VOLTAGE SENSE SETTING:
The unit will monitor the voltage level of the battery during remote start, wait for the voltage to drop while
cranking, then look for the voltage level to go above the level it was before the vehicle began to crank
which indicates the vehicle is running. Feature #14 of Bank 3 must be set for averaging time or the voltage
sense feature will not operate indicated by the parking lights flashing 7 times.
2) TACH RATE SETTING:
1. Turn the ignition key to the On position.
2. Press and release the valet/program push button switch 3 times.
3. Immediately turn the ignition key Off.
4. Press and hold the valet/program push button switch, then start the vehicle using the key.
5. When the unit senses the tach signal, the parking lights will begin to flash.
6. Release the valet/program pushbutton switch. The parking lights will turn on for three seconds to indi-
cate that the learned tach signal is stored and the unit is out of the tach learn mode.
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 Green/Orange wire to the
proper tach signal, and then repeat the tach learn routine.
3) DBI TACH SETTING:
Selecting this setting in the option menu indicates that you have a DBI module and have determined that
a tach signal is available for the vehicle you are connecting to. The unit will look at the DBI data port for
the tach signal. If the vehicle fails to start, or the unit flashes 7 times, recheck the DBI manual to insure
that tach is available for your vehicle. If not the tach connection wire, Green/Orange must be used.
4) HYBRID SETTING:
Selecting this setting in the option menu allows for Hybrid vehicles. Also feature #14 of Bank 3 must be
set for preset time or the Hybrid feature will not operate indicated by the parking lights flashing 7 times.
CRANK AVERAGING:
When Feature 14 Bank 3 is set for crank averaging, the remote start unit constantly monitors and learns
the cranking patterns of the vehicle each time the car is started with the key. The vehicle must be started
at least 4 times with the key for the crank averaging circuit to begin it's monitoring the vehicle's engine.
DIAGNOSTICS:
Enter Bank 3 and turn on selectable feature # 10 as described on the front pages of this manual.
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 inhibit wire activation
4 Flashes NA
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
8 Flashes Negative inhibit wire
