Troubleshooting: Remote start

The remote will not activate the remote start

1. Does the neutral safety input have a ground? if the wire is not grounded the remote start will not

activate.

2. Have you performed the remote start shutdown diagnostics? Sometimes an active shutdown input will

report in the diagnostics.

3. Is the remote programmed to the system?

4. Can the remote start be activated manually by applying a ground pulse to the H1/4 White/Blue

wire? Grounding the white/blue the correct amount of times activates remote start without using the

remote.

5. Check the harnesses and their connections. Make sure that the harnesses are completely plugged into

the remote start module. Make sure there are good connections to the vehicle wiring.

6. Check voltage and fuses on the system.

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 5. If there is no voltage present, advance to Step 2.

2. Check the 30A fuses.

3. If the wait-to-start timer is turned on, the starter will not crank.

4. Is the tach wire connected? If so disconnect it and remote start the vehicle to see if the purple wire

sends out voltage. If you get voltage, go to an alternate tach source. The tach wire you are currently

on has a voltage spike when the ignition is powered up, which can cause the remote start to not send

out the crank voltage.

5. Is the vehicle a Chrysler or GM with a multiplexed starter wire? The vehicle will not crank if the resis-

tance is incorrect on the multiplexed accessory/starter wire.

6. Is the vehicle a GM? If so the PINK/WHITE 2nd accessory needs to be powered up on some of the

vehicles for the vehicle to crank.

7. Does the vehicle have an immobilizer? Some immobilizer systems will not allow the vehicle to crank

if active.

8. Check connections. The heavy gauge remote start input wires on the heavy gauge 6-pin connector

should have a solid connection.

The vehicle starts, but immediately dies.

1. Does the vehicle have an immobilizer? The vehicle’s immobilizer can cut the fuel and/or spark during

unauthorized starting attempts.

2. Is the remote start programmed for virtual tach or voltage sense? If so, the crank time may not be set

high enough. Voltage sense will not work on some vehicles.

3. Is the remote start in tach mode? If so has the tach been programmed to the system?

4. Check diagnostics. Sometimes a shutdown will become active during cranking or just after crank-

ing.

The vehicle starts, but the starter keeps running.

1. Is the system programmed for engine checking off or virtual tach voltage sense? When programmed

for either of these features, the engine cranks for the pre programmed crank time regardless of how

long it takes for the vehicle to actually start. Adjust to a lower cranking time.

2. Was the Tach Learn successful? The LED must light solid and bright to indicate a successful learn.

3. Make sure that there is a tach signal at the purple/white tach input wire of the remote start. If there

is not a tach signal, 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.

4. Is an ignition or accessory output wire connected to the starter wire of the vehicle? Verify the color

of the starter wire in the vehicle and conﬁrm that an ignition or an accessory output is not connected

to that wire.

The vehicle starts, but will only run for 10 seconds

1. Is the remote start programmed for voltage sense? If this does not work, a tach wire should be

used.

2. Check shutdown diagnostics.
