battery drain

[adam_w]

Hi guys,

I've recently inherited my Granadads old 6th gen accord 2L auto but there is a battery drain on it that I have narrowed down to the brake light circuit. I've tried unplugging the pedal switch but that makes no difference, is there anything else I can try as I'm all out of ideas now. Also does anyone have a wiring diagram of the car as that would be really useful!

Many thanks,

Adam

Go to the pinned "6th gen and earlier manuels"

Follow instructions and download. Good wiring diagrams

Hi Phil,

Thanks for pointing me in the right direction, those wiring diagrams were most helpful! I've now managed to locate the drain down to a single wire, the white/blue one that goes from the Key Interlock Switch to the drivers Multiplex Control Unit but i have no idea what it does, any ideas? If this is the root of the issue, does that suggest that i need to replace the mulitplexer or is there anything else that this could be related to? Any help you or anyone else could give would be greatly appreciated!

Kind regards,

Adam
