Check remote startup diagnostics.
Is the neutral safety switch installed and turned on? Is the neutral safety wire grounded?
If the vehicle has an automatic transmission, make sure the remote start is programmed for Automatic
Transmission mode.
Is the remote programmed to the system?
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.
Check voltage and fuses on all wires and harnesses with fuse holders.
Check for voltage on the starter output wire two seconds after the remote start becomes active. If there is
voltage present, skip to Step 8. If there is not voltage present, advance to Step 2.
Check all fuses.
If the wait-to-start wire is detecting ground upon activation, the starter will not crank.
Is the tach wire connected? If so disconnect it and remote start the vehicle to see if the starter output wire
sends out voltage. If you get voltage you will need to go to an alternate tach source, the tach wire you
are currently on has a voltage spike upon ignition power up which can cause the remote start to not send
out the crank voltage.
Is the vehicle a Chrysler or GM with a multiplexed starter wire? The vehicle will not crank if the resistance
is incorrect on the multiplexed accessory/starter wire.
Is the vehicle a GM? If so the 2nd accessory needs to be powered up on some of the vehicles for the
vehicle to crank.
If this is a manual transmission vehicle, the clutch will need to be bypassed (see tech tip # 10000 at www.
directechs.com).
Make sure the starter output wire is connected on the starter side of any optional starter kill/anti-grind relay.
Does the vehicle have an immobilizer? Some immobilizer systems will not allow the vehicle to crank if
active.
nection. "T-taps" or "scotch locks" are not recommended.
Does the vehicle have an immobilizer? The vehicle's immobilizer can cut the fuel and/or spark during
unauthorized starting attempts.
Is the remote start programmed engine checking off or voltage sense? If so, the crank time may not be set
high enough. Voltage sense will not work on some vehicles.
Is the remote start in tach mode? If so has the tach been programmed to the system?
Check diagnostics. Sometimes a shutdown will become active during cranking or just after cranking.
Is the system programmed for engine checking off or 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 shorter cranking time.
Was the Tach Learn successful? The LED must light solid and bright to indicate a successful learn.
Make sure that there is a tach signal at the 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.
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.
Is the remote start programmed for voltage sense? If this does not work, a tach wire should be used.
Check shutdown diagnostics.
Either the wrong accessory wire is being energized or more than one ignition or accessory wire must be
energized in order to operate the climate control system.
If the vehicle has an electronic climate control system some will reset when the key is turned off and then
back on, unfortunately this is a function of the vehicle and cannot be bypassed.
