Hybrid Honda civic 2005 SolvedSolved

Honda Civic 2005  150000 miles
Suddenly many functions stopped working: the alarm is out of order, the door locks do not respond to their button, the interior light turns on at any moment, the hybrid system seems to be always discharged, leds from the gears flicker, the entrance for the scanner doens't work and even the stereo turns off. There are no burnt fuses, any idea what it may be?

Open the hood or bonnet and there you will find some other fuses. There is one called "backup" or something similar. That one usually burns out.
augie20 from United States 11 years ago
Thank you earnest. Checked that and the problem is: fuse that I introduce, it is burnt out.

earnest from United States 11 years ago
You must have a short circuit in the wiring. Is there something you have recently installed on your car? That could be the cause.
augie20 from United States 11 years ago
The last installation was the scanner and it is not working since then. The short circuit could be in its plug, right earnest?
earnest from United States 11 years ago
Most probably. You should check whether it is damaged or shorted, otherwise you'll have to change the scanner connector.
augie20 from United States 11 years ago
You were right, there was a short circuit in the connector. Thanks for your help.

The first thing is to start it or jump start it with another battery. The second thing after starting it is to check that the battery is working well, and that you haven't left anything turned on.
Val02 from United States 11 years ago
If it doesn't start at all, not even a light bulb, check the fuse right next to the battery because it must be burnt.

Please help. I have a JDM 99 honda civic ex coupe and after buying a new battery it died after two weeks. I checked the underhood relays & fuses and they were all good. Car will intermittently start giving me ACC 1 & 2 but as soon as I turn to crank all power shuts off and it wont come back until like days later. I replaced a relay that was under the dash and the ignition switch and still nothing. Before I replaced the relay it was beeping with key recognition but now I get nothing.

Remote start wiring damage killed the horn SolvedSolved

Honda Civic 2009 Sedan 95000 miles
The remote start wiring got damaged and now the horn does not work (nor does the remote start, but I don’t care about that). Even shutting off the valet switch didn’t restore the horn, although it allowed remote start once. The fuse looks fine, but other than replacing that, does the entire remote system have to be removed in order to fix the horn? Thanks.

Mechanics checked the electrical and the horns had power. They ended up whacking one of them with a rubber mallet which made one sound, at least. They also found the radiator rusting out, which is one expense too many. Trading it.

Won't start after some time on

Honda Civic 1998  200000 miles
My vehicle works properly for up to 20 minutes and it then stalls. I wait for around 10 minutes and it starts as if nothing had happened. I've been told that the problem can be the coil, some relay which is before the coil or the fuse box. Everything is now new but the problem remains, can anyone give me a hand?

You should check both the camshaft and the crankshaft sensors. One of them must be the cause of your problem.

Engine start problems

I thought it was the battery, but I got it checked checked and the technician said that both the battery and the alternator were fine. Later I went to do some shoppings, I got off the car and when I returned It just wouldn't start. It just makes a little sound because of the starter.

Ground strap to battery has voltage on it. SolvedSolved

Honda Civic 1998 Ex coupe  260000 miles
While driving on the freeway I noticed the engine light was blinking, but only three blinks then a pause of about 20 seconds then 3 more blinks. At that point I had been driving a total of about 7 minutes. Roughly 4 off and 3 or so on the freeway. The car drove fine this whole time/ nothing to make me even think of the light coming on so I kept driving (about 15 more minutes home) knowing that it's not what's is suggested. Anyhow I got home went in to eat and came out to hook up my scanner (Autel AL519) will no luck. I started the car to collect info on scanner of live feed, but the scanner do… Read complete

Energized Ground Strap from United States 3 years ago
After a long week of testing circuits and searching for a grounded wire somewhere I had the electrical hooked back up with just the alternator unhooked. Once I hooked that up it caused the voltage on the ground strap to rise and become stronger. So I replaced the alternator and that fixed the energized ground strap issue. I have an idle issue now along with strange driving conditions so I'm waiting to see if it throws a code for something failing. I've driven almost 200 miles though so I'm not sure if a code is going to be presented.

Radio and electrics

Honda Civic 2011 1800 SOHC i-VTEC 58000 miles
I can get the radio and CD and Aux to work sometimes but mostly not working. The CD player actually plays the disc but no sound. When I start the car it shows 'RADIO 1' with a telephone symbol. As soon as i press any button on the device it immediately changes the display to '1 AF ON' with the telephone symbol but nothing works when pressed and no sound. The Central locking sometimes stops working but opens with the key. I also looked at the dashboard layout with the ignition on for about 15 to 20 minutes and the car would not turn over. But after another 5 to 10 minutes suddenly worked fine.… Read complete

It sounds like there could be a few different issues with your Honda Civic. The radio and CD player not working, the central locking system malfunctioning, and the battery issues could all be related or separate problems.
It is possible that the battery with dead cells is causing the electrical problems in the vehicle, including the radio and CD player, and the central locking system. If the battery is weak, it may not be providing enough power to all of the electrical components, which can result in them not functioning properly.
However, it is also possible that there is a separate issue with the electrical system, such as a wiring problem, a blown fuse, or a problem with the alternator. In this case, a new battery would not solve the problem.
I would recommend having a professional mechanic inspect the vehicle to diagnose the issue and recommend the necessary repairs. They can perform a full electrical system check to determine the root cause of the problem and ensure that all of the components are functioning properly.
Peewee from Great Britain 4 years ago
Thanks Bruce. I will get it checked out before it gets worse.
Maymoe from United States 3 years ago
This is happening to me. I had starter, battery, alternator replaced and ignition control module. It still is wonky. It goes from am to FM to aux, to not working to turning on and it being very loud and it just beeps and beeps. It's crazy. I believe it's another faulty ignition control module. But the dealership won't even consider it being that. I explained to them that when they first put it in it worked great and after a day it's bad again and now my key fob with new battery does not lock/unlock my car. They key works great but that's my issue. I only have 134k miles.

New battery, lights and radio come on.

Honda Civic 2000 4 cylinder LX 123000 miles
I just put a new battery in my LX and it still won't start. I listened for sounds, no clicks. All of the dash warning lights, headlights, radio, and even AC come on when I turn the key, but no vroom vroom. Strange thing is the hazards lights start blinking and won't go off, not even when I turn the car off. After wiggling the turn signal stick a little and pressing the hazard button in a few times it cuts off. But when I open the door of the car the hazards come on again, and are accompanied by ding ding sound like when door is ajar--even after door is shut. I was thinking electrical problem

It turns out that the previous owners had a type of after market alarm system that was also equipped with a type of fail start button installed in the car. So the car will only start after either the button is pushed or the alarm is disabled.

Lights flicker and transmission fails

Honda Civic 2000  115000 miles
Whenever I start driving my Honda Civic 2000, I can feel a hard knock in the transmission and both the "check engine" and the d4 lights stay on. Even more, at the beginning it has lots of trouble to speed up. As code p0753 appeared, I changed the shift control solenoid but everything remained the same. I then checked the fuses under the dashboard and noticed that there was one blown fuse in position number 15. Once I change it, the lights and transmission return to normal, but after driving for a while the same fuse melts and the problem returns. Can anyone help me? Thank you in advance.

Engine turns, but won't start

Honda Civic 2000 Civic dx 200000 miles
I have gone through the electrical, new starter, new distributor, new battery, as well as plugs and wires. Even while trying to jump it, nothing happens. Only thing I can think of that could be it, would be the neutral safety switch. But I thought of that too late. My car is now snowed in. Is there possibly anything else I could have missed? Any questions to help clarify diagnose the problem, I am happy to answer. I've been scratching my head on this for a while.

Car will randomly not start and go into accessory mode

My car will sometimes refuse to start on the first try up to the 5th try. I have gone through all my fuses and checked my battery. I was told it was my alternator because it tested bad, so I replaced it. This did not fix it. I even thought it could be my starter but I can hear it clicking like it wants to start but the car will not crank. Any help is greatly appreciated as I would like to fix it on my own.

2012 Honda Civic Coupe - Issue After Replacing Battery

My car sat all winter. I just replaced the battery, and now warning lights remain ON. The stereo won't work, either...nothing happens when I press "Source" and nothing happens when I try to turn on the radio/CD player.
I am afraid to drive the vehicle, but it was in perfect working condition when I last drove it.
Through my research, I learned a few things...it could be sensors or fuses. Or, I could drive it around and see if the lights go off?

2022 Honda Civic USB port charging but CarPlay not working

Honda Civic 2022  37000 miles
My 2022 Honda Civic Sport’s USB port charges the phone, but Apple CarPlay is not detected when I press Connect. It worked normally for several months and suddenly stopped working.
I tested two different data-capable cables and two different phones. The second phone connected briefly, but CarPlay stopped working again. Bluetooth, the display, and phone charging still work.
I restarted the phones and vehicle, removed and reconnected the phone, and performed a factory data reset on the Honda infotainment system, but the problem remains. Could this be a faulty USB data port/module, connection, or wiring harness?
