Does anyone have a headlight wiring diagram for a 2008 2.2 CDTI 5Dr EX HID Headlights, No DRL, Auto Wipers?

I've looked on the FN2workshop site, found the relevant version, however i want to make SURE there is no difference with the 3/5 door!

Symptoms:

Auto headlights & auto wipers do not function on auto.

Headlights remain in Off mode, no sidelights no dip

Wipers wipe as a standard intermittent with the adjustment knob changing the frequency - they park fine so not a motor issue.

It has been to Honda and they have "diagnosed" it as the sensor (£534 inc fitting and VAT!) - however....

I used the FN2workshop, Rain Sensor Input Test method myself, and found that one of the continuity tests between Rain Sensor connector BRN and pin 4 of the lighting stalk connector fails - pin 10 and BRN OK

Leading me to think there could be a break in the wire somewhere - any known common places?

FIRST: If anyone can confirm that the input test for the 5 door is the same that would be appreciated.

SECOND: If anyone has a spare known working rain sensor i can try?

THIRD: Any other bright ideas - all fuses OK and battery full BTW, also already tried the disconnect battery for 15mins trick

I've not tried the PNK tests yet as it seems like a real pain to get the relevant connector! Going to talk to the Honda tech tomorrow to see what he actually tried.....

Cheers chaps,

Auto Wipers & Headlight Not Working

Just thought I'd try and keep this up to date to help anyone in the future.

I called in to chat with the extremely helpful Honda w/s foreman at the Greenacre in Blackburn on Friday and got a bit more info - he worked on the car when it was in previously

Wiring is the same for 3 / 5 door to do with the headlights/wipers as to be expected.

Input tests are also all the same.

He sent the query down to HUK technical who then came back;

Try charging battery - Auto Wipers will only function if the battery is 12.4V + -I'll report back

Rather than a faulty sensor, they suspect it may be a faulty MICU, only way to test is to have it swapped out. HUK are going to see if they have a part that can be sent up for testing purposes.

So.....if anyone has a known good MICU around that could be useful for me ! Still may come back to be the sensor is knackered tho!

I had similar issues with auto lights and wipers on mine. It was fuse #1 that had blown in the internal fuse box.

I do have a spare sensor which I picked up for £30 off a user here. Let me know if you need it as its just sitting around.

I was also thinking of a micu replacement on mine but manually checked each fuse and luckily enough fuse 1 was the culprit.

Cheers for the thought. I'll double double check it tonight and swap it out for another good one as well.

I'm sure I've checked that one already but it does no harm!

I'll let you know on the sensor as soon as i can - I take it you know it's a working one, always dubious of eBay car electronics sensors etc, knowing how 'gentle' breakers etc aren't!!

Just thought I'd update this for completeness.

Bought a used Rain / Light sensor off our favourite auction site for £20 last week.

Fitted it just now, it only bloody works!!!!!!!! (Not tried the rainy bit yet, but the auto lights do, so partial success at the moment at least!)

Just to finish off (for the moment at least)

After testing the rain portion, still to no avail, I was a bit downhearted. I then remembered a post on here and what the Honda tech mentioned.

Try disconnecting the battery.

Heyf****ingpresto!

I, at this moment in time at least, have auto wipers and auto headlights on my EX.

Did get a funny look from a passerby mind you, as I'm stood there with a squirty bottle of water pointed at the screen, punching the air with a cry of "Get in!"[smilie=666.gif]
