Recently, I have been unable to remote start my 2003 Honda Accord Coupe. I brought the car to an auto-zone, and they told me (after hooking my battery up to a voltage tester) that I had "low voltage" when remote starting, but my battery was completely healthy.

What steps should I take to investigate this further? Could it simply be the wire to the remote starter is too frayed?

    Does the same issue exist when you start the car normally, with a key in the ignition? – CharlieRB Jan 26 '17 at 12:35
  • Correct me if I am wrong, but I don't think the 03 Accord came with remote start from the factory did it? Is it aftermarket remote start? – Zshoulders Jan 26 '17 at 17:40
  • @charlieRB it works great with the key, there is only a problem with the remote start. – wizlog Jan 26 '17 at 18:46
  • That is correct, an aftermarket Prestige remote start system was installed. – wizlog Jan 26 '17 at 18:47
  • I added photos and videos – wizlog Jan 27 '17 at 2:13

A frayed wire could definitely be the cause. What is the, "wire to the remote starter" and what is it's function?

Starting a car, remotely or otherwise, requires a large wire to provide power from the battery to the starter motor, usually through a relay. If you have a bad connection such as wire that's not large enough, wire that is damaged or frayed, or corrosion, the starter motor won't be able to get enough power from the battery and it will struggle to start the car.

It sounds like the full power from the battery isn't getting through to the starter motor. Does this happen when turning the car over with the key? I'd be curious to know more about how the remote starter is integrated into the car's existing starting circuit.

  • I added two photos of the frayed wire, and a video of the car not starting. the car starts wonderfully when the key is in the ignition. – wizlog Jan 27 '17 at 2:14
  • When I use the key, it turns over once it twice and starts immediately. – wizlog Jan 27 '17 at 17:17

Remote start is not a separate starting system. It is an electronic control that triggers the existing system to start the engine. Since your car starts by key without issue, I suspect the problem you are having is not related to the car battery or starter itself.

Likely what is happening is the battery in your remote is low or dead causing no signal. Before you start chasing wires, change the battery in the remote first.

  • The battery was low when this problem started, and the remoted indicateed that. I just replaced it with a new Duracell battery and the remote shows a full charge. The problem persists though. – wizlog Jan 27 '17 at 1:18
  • I uploaded a video of the car not starting and two photos of the battery connection to the remote starter. Maybe that would help? – wizlog Jan 27 '17 at 2:14
