lite. Also make sure that the ground wire is going to a chassis ground and not to something under the dash.
3. Check diagnostics. The diagnostics will tell you which shutdown is active or not connected.
The remote start will activate but the starter never engages.
1. Check for voltage on the purple starter wire two seconds after the remote start becomes active. If there is
voltage present, skip to Step 4. If there is not voltage present, advance to Step 2.
2. Check the 30A fuses.
3. Check diagnostics. If the gray/black wire is detecting ground upon activation, the starter will not crank.
4. Make sure the purple starter wire is connected on the starter side of the optional starter kill relay.
5. Does the vehicle have an immobilizer? Some immobilizer systems will not allow the vehicle to crank if active.
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 unau-
thorized 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 running.
1. Is the system programmed for engine checking 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 voltage reference. If
this does not work, a tach wire should be used.
2. Check diagnostics.
