“SMART TACHLESS” MODE
This RS900/901/999FM systems includes a unique voltage monitor system called “Smart Tachless” mode. This mode
allows this unit to efficiently start an engine without the use of a tach signal wire. These modules actively monitor the
voltage level of the vehicle to control the starter motor each time a remote start is requested.
IMPORTANT NOTES:
(1) SETUP may be required for the RS900/901/999FM “Smart Tachless” Mode. If your vehicle has not been at rest for a
period of time (Hot engine), then you must drain the surface charge from the battery. Unplug main power harness
from unit, turn HEADLIGHTS ON for 4 minutes to drain off excess surface charge on vehicle’s battery then
reconnect.
(2) On the rare occasion that “Smart Tachless” mode does not operate satisfactorily, change the voltage reference level
as described on the next page, or use a different mode such as “Tach Reference” mode, or “Timed Crank” mode.
