“SMART” TACHLESS MODE
This CoolStart system includes a unique voltage monitor called “Smart Tachless” mode that 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 “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 the “Tach Reference” mode.
