Brown/Black Wire:
250 mA Horn Output
The Brown/Black wire is provided to beep the vehicle’s horn. This is a transistorized
low current output, and should only be connected to the low current ground output
from the vehicle’s horn switch. If the vehicle uses a + 12 VDC horn switch, then
connect the brown/black wire to terminal 86 of the AS 9256 relay ( or an equivalent
30 Amp automotive relay ),and connect relay terminal 85 to a fused + 12 VDC
battery source. Connect relay terminal 87 to the vehicle’s horn switch output, and
connect relay terminal 30 to a fused + 12 VDC battery source.
Programming Tach Rate:
NOTE: All applications require that the tach be programmed.
The unit will not operate unless tach is programmed. If an attempt is made to start the
vehicle via the remote start without 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 for the specific vehicle, the unit may not realize that the vehicle is
running and in certain instances re-engage the starter motor.
The Remote Start Unit will learn the tach rate of most vehicle's single coil, multiple coil
packs, or single injector. To learn tach:
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. Wait for at least 5 flashes
7. Release the valet/program switch. The parking lights come on for three seconds to
indicate that the learned tachometer signal is stored and the unit is out of the
tachometer 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 Purple/White wire to the proper tach signal, and then
repeat the tach learn routine.
Setting Up The System Programmable Features:
Bank 1 Transmitter Programming Channels
Start with the system disarmed, turn the ignition switch to the on position then:
1. Press and release the push button valet/program switch 3 times. The siren chirps
once and/or the lights flash one time indicating the transmitter program mode
successfully entered.
2. Press the transmitter button until a chirp from the horn is heard for each
transmitter you wish to program. See the Owner’s Manual for additional transmitter
programming information.
3. Turn the ignition switch off then on to access Bank 2 Keyless/Alarm feature
selections.
1 Flash + 1 Short & 1 Long chirp when the ignition transitions off, followed by 1
