Mark59 Posted July 8, 2023 Share Posted July 8, 2023 Hello all. I have a question that is causing me problems. My 2007 Honda crv 2.2cdti is not holding charge. I can take it on a long run during the day and the next morning it wont start. I then charge the battery for around 10 mins and all OK again. I have had the battery and alternator checked and they are both in great condition but something is draining the battery. Please can anyone suggest what it might be. Thank you.

hondream Posted July 8, 2023 Share Posted July 8, 2023 It's a known issue. Your Bluetooth thingy is causing a parasitic drain. Disconnect it. But then you can't use the voice commands Quote Link to comment Share on other sites More sharing options...

hondream Posted July 9, 2023 Share Posted July 9, 2023 This post was recognized by Trevor! hondream was awarded the badge 'Great Support' and 30 points. It is an issue on the Accord's, and these cars will share the same components. You will have to get an Amp-clamp (or similar) and see how much current is being drained when the car is parked. And then start unplugging the fuses one by one to isolate the parasitic drain. Quote Link to comment Share on other sites More sharing options...
Mark59 Posted July 12, 2023 Author Share Posted July 12, 2023 Is there a way to disconnect the blue tooth function on my car to see if it is that causing the battery drain. Quote Link to comment Share on other sites More sharing options...
Mark59 Posted July 15, 2023 Author Share Posted July 15, 2023 I have looked on you tube and listened to what has been said on here and found the Bluetooth module. I have now pulled the plug connector and will let you know if the problem is fixed. Thank you all for the help. Quote Link to comment Share on other sites More sharing options...
Mark59 Posted July 16, 2023 Author Share Posted July 16, 2023 All seems to be working OK now. I dont have Bluetooth but I didnt use it anyway but the car starts first time now so problem sorted. Thank you all again for your help. Quote Link to comment Share on other sites More sharing options...
