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 vehicle’s 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.

■

Diesel vehicle does not wait to start.

1. Is the GRAY/BLACK wire connected to the wait-to-start wire of the vehicle?

2. Check the polarity of the wait-to-start wire. (See the

Finding the Wait-to-Start Bulb Wire For Diesels

section

of this guide.)

3. If wiring a negative wait-to-start bulb, make sure that a diode has been placed in line on the factory wire

between the vehicle’s ECM and the wait-to-start bulb. (See wiring description for the

H1/6 GRAY/BLACK (-)
