Thanks, I'll look there next. Would it turn over if the ignition switch was faulty?There are some maxi fuses tucked down the front of the under bonnet fuse box which control a lot of circuits. It also worth checking power at main Ign switch terminals with the Ign on . I have seen a few failed Ign switches over the years on older Peugeots
What year is your 307? I had a quick look at the wiring for a 2005 307 see the image below. This diagram may not apply to your car I need to know the year and RPO number (usually inside the drivers door). However, if it's the correct diagram the fact that the engine is cranking suggests F11 is getting power from the maxi-fuses. It could be the ignition switch but it's odd there is no voltage at pin 16 of the OBD connector. This should be on all the time.Would it turn over if the ignition switch was faulty?
Your car has the older wiring system and the older VAN bus protocol (Vehicle Access Network). Thanks to Madbadandold looking up the diagnostic code. I think you are getting this code because the BSI is not powered up.Thanks for your help, you obviously know a lot more abour electrics than I do. Its a 2004 307 2.0 90 hdi. RPO 10180. There IS voltage at pin 16 OBD, but the socket wont operate my scanner. The car had been sat for four months and the previous battery was down to 9 volts. I can do all the mechanicals but electrics is my real weak suit. Its too nice to scrap but not really worth spending much money on.
The car is probably in Economy Mode which would explain why somethings are not working. There are a couple of things of concern- the car is not passing the beep test and the multifunction display is not working. My concern is that the BSI got corrupted when the battery voltage dropped.Many thanks, at least I can eliminate things. Brake lights work, reversing light works, side lights work, 12v socket works, glove box light works. No horn, no dashboard lights or multifunction display whatsoever, indicators dont work, hazards dont work. Fog light doesnt work, headlights dont work.
I think might be worth trying to restart the BSI. The important thing to do is leave drivers window open (or a door if you can't open the window). Wait 3 minutes until the odometer display goes out and then disconnect the battery for a few minutes. Then reconnect the battery and turn the sidelights on. Then turn the ignition on.Already have the glovebox out and the BSI exposed. I think I've done that but I'll check.
