Looking for troubleshooting assistance as to reason why vehicle will not start..
I have a Honda Accord and the alarm system was installed. when trying to start system, all lights appear on dash to show ignition is enabled , but when you turn the key fully, it does not crank the starter. A voltage probe of the ignition harness shows that when in the ON state, the ignition wire shows 12v, however, when cranking, the starter wire reads about 9v. This may be normal, given the current draw, but not too certain.
With the immobilizer circuit bypassed (by removing the alarm system and ignition and starter wires reconnected), the starter cranks without issue. I have had the alarm brain replaced 3 times thinking it was an alarm issue, but it has been the same issue with all units that have been sent to me, so I doubt that I have a defective brain unit.
Has anyone experienced this? Any thoughts on how to correct? Any help would be appreciated.
Thanks
Re: Looking for troubleshooting assistance as to reason...
There is likely a relay installed in the circuit for the starter crank form the alarm/immobilizer. The contacts on these relays will arc when mating and separating due the large current being drawn by the starter. This will cause pitting on the contacts and result in a voltage drop (thus the 9V). This voltage is not sufficient to engage most starters. Locate and replace the defective relay.
Testimonial: "Thanks for the response. The immobilizer relay is built into the alarm brain, so there is no way to replace. I also find it unlikely that I have had 3 replacements with the same issue. Any other thoughts?"

Tip: The max point reward for answering a question is 15.
lets look at the basics to get a vehicle to start.
air: make sure there are no obstructions in the air box and tube leading to intake.
fuel: turn the key to accessory and listen for the fuel pump to make a noise (it is helpful to have an assistant listen as you may hear other noises inside the vehicle)
spark:
part one: ensure the battery is fully charged.
part two: check the ensure that the ignition system is operational.
many parts stores sell a cheap inline spark tester that can be installing onto any plug wire and will have a light to show if there is spark.
once you have crossed these off the list then it is time for further examination. usually one of these three items lead to the reason.
Cheers!
If your Viper 5706V car alarm and remote start system is displaying error messages and not functioning properly, there could be several reasons for this issue. Here are some steps you can take to troubleshoot the problem:
Check the Display: Look closely at the error messages displayed on the remote control or alarm system. These messages can provide valuable information about what might be causing the problem.
Check the Wiring: Make sure all the wiring connections are secure and properly connected. Loose or damaged wires can cause communication errors and prevent the system from functioning correctly.
Check the Battery: Ensure that the battery in both the remote control and the vehicle is fully charged. Weak batteries can lead to communication problems and errors.
Reset the System: Try resetting the Viper system by disconnecting the vehicle's battery for a few minutes and then reconnecting it. This can sometimes clear any temporary glitches in the system.
Check Antenna Placement: The antenna for the remote start system should be placed in a location that allows for clear communication between the remote control and the vehicle. Check if the antenna is properly positioned and not obstructed.
Review the Manual: Refer to the user manual that came with your Viper 5706V system. It may contain troubleshooting steps and error code explanations specific to your model.
Seek Professional Help: If you're unable to resolve the issue on your own, consider seeking assistance from a professional car alarm installer or a Viper authorized dealer. They have the expertise and tools to diagnose and fix complex issues.
Update the Firmware: If the system's firmware can be updated, consider updating it to the latest version. New firmware releases often include bug fixes and improvements that could address the error messages you're encountering.
Remote Control Programming: Sometimes, error messages can be due to issues with remote control programming. Follow the instructions in the manual to reprogram the remote control to the system.
Check Sensor Connections: If your Viper system includes additional sensors or accessories (such as door sensors or motion detectors), ensure that they are properly connected and functioning.
Remember that troubleshooting complex car alarm and remote start systems might require specialized knowledge and tools. If you're not comfortable with the troubleshooting steps or if the issue persists, it's recommended to consult with a professional who is experienced in car alarm and remote start installations.
You will need to reset the security system and your key. You will need a specific code to do so. You need to call the dealership with your vehicle information so you can get the code. I would do this asap, because it can cause the car not to start. If you need anything, write back. Thank you for using FixYa.
The factory alarm needs to be disarmed prior to remote starting the vehicle. You could either add a data door lock module (HODL5) to the 4113LX to disarm the alarm or, you could extend the light green with black from the 4113 and run the wire into the drivers door and connect to the brown at the power window master switch. Test this wire while turning the key in the door.
Avital and viper remotes even though they look the same, they operate at different freqs. Im a retired alarm installer i could never get them to interchange.
Hi, Does the vehicle have an aftermarket alarm system? Is the valet switch for this what you are looking for? If so, it depends entirely on who installed it as where they have put it, although it's usually under the dash on the driver’s side. Some alarms have different sequences that you have to go through to put the alarm into valet mode; it's not usually just a switch that you flick. Best to pop into an alarm or stereo installer and see if they can spot it for you, or if the car is immobilized, find out what sort of alarm it is and call an installer for the info on the valet procedure.
