viper 5902 completed 1

I just completed my first car alarm install and let me tell you, it was not easy, but it was very rewarding. Everything appears to work: trunk sensor, hood sensor, door sensor, parking lights, trunk popper and all the general things, but what I am having issues with is my remote start. My remote start cranks fine and starts the vehicle, but then it dies after 5 or 6 seconds. It doesn't appear to be the immobilizer because the green key is not flashing, and I've also tried to remote start with my key in the ignition; again, same results, starts for 5 secs than dies. The 5902 defaults to 3 attempts, and reports back to my 2-way with a 'low battery' message along with a car battery icon. I'm currently set up on virtual tach for the moment. Could this be the cause? Also, my car starts fine without the remote start, so I'm assuming my wires to the ignition should be correct, right? Here are the specs: -2005 Acura TSX (auto) -Viper 5902 -Canmax400dei (Honda4 firmware ver. 1.00) -507M Tilt (tested...works fine) -520T backup battery (tested...works fine) Any advice would be greatly appreciated.

Wow. Thanks for the quick reply guys. The idea about starting the car w/ the key and removing it was clever. Good thinking. Anyway, I tried it and it actually stayed on after I removed the key. I also tapped the brake to see if it would shut off, and it did. Afterwards, I attempted to remote start w/out the key but it shut off again after a few seconds. I then put the key back in, set it to the 'ON' position (which I didn't do before...I just left it in the 1st position earlier) and it stayed on. But to my suprise, I also noticed that it made the starter turn excessively while intializing the remote start. After realizing this starter issue, I again attempted the remote start w/out key to see if it would repeat the starter overturn, and it did, all the way until the engine shut-off (4-5 secs). This may be why I'm receiving the 'Low Battery' msg. Recap in case I may have confused you: -Started w/ key, remote started, removed key = worked -Key to ON position, remote started, starter grinded, removed key = worked -Remote started w/out key, started grinded = did not work It's something to do with the starter, any idea?

Just wanted to clarify that after remote starting w/out key, the engine does run, but the starter keeps turning until the engine shuts-off.

I am new to all this and can't find an install manyal for the 5902 but It almost sounds like the remote start is not getting the information about the vehicles battery. Have you tried to reprogram the virtual tach? I would look into the voltage sence becuase it sounds like that is where your issue is. Here is what my 5901 install manual says about your problems

The vehicle starts, but immediately dies.

1. Does the vehicle have an immobilizer? The vehicle’s immobilizer cuts thefuel and/or spark during unauthorized starting attempts.2. Is the remote start programmed for virtual tach or voltage sense? If so, thecrank time may not be set high enough. Voltage sense does not work onsome vehicles.3. Check diagnostics. Sometimes a shutdown becomes active during crankingor just after cranking.

• The vehicle starts, but the starter keeps running.

1. Is the system programmed for engine checking off or virtual tach voltagesense? When programmed for either of these features, the engine cranksfor the preprogrammed crank time regardless of how long it takes for thevehicle to actually start. Adjust to a lower cranking time.2. Was the Tach Learn successful? The LED must light solid and bright toindicate a successful learn.3. Make sure that there is a tach signal at the PURPLE / white tach input wireof the remote start. If there is not a tach signal, recheck the connection tothe vehicle’s tach wire and make sure the wire is not broken or shorted toground leading to the remote start.

• The vehicle starts, but only runs for 10 seconds.

1. Is the remote start programmed for voltage sense? If this does not work, atach wire should be used.2. Check shutdown diagnostics.• The climate control system does not work while the unit is operating thevehicle.Either the wrong accessory wire is being energized or more than one ignitionor accessory wire must be energized in order to operate the climate controlsystem.

Also here is the shutdown diagnostics for the 5901 you will need to cross reference to the 5902

Shutdown diagnostics

To perform shutdown diagnostics:1. With the ignition OFF, press and hold the Valet/Program switch.2. Turn the ignition ON and then back OFF while holding the Valet/Programswitch.3. Release the Valet/Program switch.4. Press and release the Valet/Program switch. The LED flashes to reportthe last shutdown for one minute or until the ignition is turned on, asshown in the following table:LED Flashes Shutdown Mode1 flash Runtime expired2 flashes Over-rev shutdown3 flashes Low or no RPM4 flashes Transmitter shutdown (or optional push button)5 flashes (+) Brake shutdown6 flashes (-) Hood shutdown7 flashes Timer mode/Turbo mode/Manual mode error *8 flashes Neutral safety shutdown9 flashes Low battery (voltage mode)10 flashes Alarm triggered **11 flashes Wait-to-start input timed out* Timer mode error: Ignition is on or shutdown input is active when activatingtimer mode.Turbo mode error: Turbo mode is programmed off, engine is not on orshutdown input is active.Manual mode error: MTS mode not enabled.** Alarm was triggered during remote start sequence.

Did you power up all the power input wires for the ignition/accessory relays on the alarm brain (I can't remember what DEI called them)? Even if the vehicle doesn't have a second accessory/ignition, you still have to power up the input on the brain. I remember my boss having remote start issues the first time we did a 5902 and that was the problem. I'd also recommend hard-wiring the tach to the vehicle.

DId you even test the wires? If your starter keeps cranking after the car is started even when you put in the key it's possible you got starter and ignition switched around. And learning tach is the right way to do it. Virtual Tach works maybe 50% of the time from my experiences.A DMM is a beautiful thing.

That symptom is the one where tach hasn't been learned. With respect to Mr. Pierson, I would suggest relearning tach but hard wired using proper tach sense not voltage reference. The over run on the starter motor is the clue. Zerep's comment is absolutely correct.
