UNGO – Remote Start Diagnostics
6. Check connections. The two red heavy gauge
input wires on the relay satellite should have solid
connections. “T-taps”, or “scotch locks” are not
recommended for any high current heavy gauge
wiring. Also, if the vehicle has more than one
12-volt input wire, then connect one red wire to
each.
The vehicle starts, but immediately dies
1. Does the vehicle have an immobilizer? The
vehicles immobilizer will cut the fuel and/or spark
during unauthorized starting attempts.
2. Is the remote start programmed for voltage
sense? If so, the start time may not be set high
enough, or you may have to adjust the voltage
threshold in programming. Voltage sense will not
work on some vehicles.
3. Check diagnostics. Sometimes a shutdown
will become active during cranking or just after
cranking.
The vehicle starts, but the starter keeps run-
ning
1. Is the system programmed for engine check-
ing off or voltage sense? When programmed for
either of these features, the engine cranks for the
preprogrammed crank time regardless of how
long it takes to start the vehicle to actually start.
Adjust to a lower cranking time.
2. Was the Tach Learn successful? The LED must
light solidly and brightly to indicate a successful
learn.
3. Make sure that there is a tach signal right at the
purple/white tach input wire of the remote start.
If not, recheck the connection to the vehicle’s
tach wire and make sure the wire is not broken or
shorted to ground leading to the remote start.
The vehicle will start and run only for about
10 seconds
1. Is the remote start programmed for voltage
sense? Try programming the unit for low volt-
age reference. If this does not work, a tach wire
should be used.
2. Check diagnostics.
