The Little Green Loop
This wire is only present in international models. This jumper wire will determine the
transmission setting. If the jumper wire is not cut the control module will be set for
manual transmission mode. (Note: The factory default is manual transmission. If the
control module is installed in a manual transmission vehicle and the jumper is cut ALL
WARRANTY is void.) When the jumper wire is cut the control module will be set for
automatic transmission mode.
Adjusting Siren Volume
To increase the volume of the siren, cut the black loop of wire located on it. This will
increase the volume of the siren by 3 dB.
Adjusting Shock Sensor Sensitivity
To adjust the sensitivity of the shock sensor, turn the dial located on it. The higher the
number, the higher the sensitivity to impacts to the vehicle. Even a small adjustment to
the dial can make a big difference in the sensitivity. Most vehicles will use a sensitivity
setting below “4”.
Programming Tach / Alternator Sensing
Tach sensing:
When using tach mode on vehicle, the tach signal must be learned to the control
module before vehicle will remote start.
Tach sensing procedure
(To test for tach sensing set digital multi-meter for AC voltage.)
1. Start the vehicle with the key. Allow time for the engine to idle down.
2. At idle the tach wire will test between 1 to 4-volts AC. As the R.P.M.’s
increase the voltage on the meter will increase.
3. While vehicle is at idle, tap the tach learn button. The parking lights will
flash once and siren will chirp once to confirm the control module accepted
the tach signal. If the parking lights flash three times and the siren chirps
three times this is confirmation that the control module did not accept the
tach signal. After two seconds the number of parking light flashes will
indicate the cause of the error.
