LIGHTS NOT WORKING - INDICATORS<>FOGS<>HAZARDS<>HIGH BEAM & FLASHER

LIGHTS NOT WORKING - INDICATORS<>FOGS<>HAZARDS<>HIGH BEAM & FLASHER :wall:
Hi all, went to go out and I found that I have no indicators (on the stick as well as off the hazard switch), no main beam (high) or headlight flasher, no front or rear fog lamps, although both front and rear lights come on OK via the main lights switch, as do the interior cluster lights. The only place I have been working was in the boot well/ battery area where I connected up the connector plugs for a new stereo.

QUESTION: Is there a module, fuse or relay I can check? :hmmm:
HELP

i'd concentrate on where you were doing your work, check connections and fuses...

[Steamyrotter]

All seem to be from the LCM module..

Try the initial disconnect battery trick as the system may have been upset by something.
Whilst disconnected check all the wiring around your mods.

sounds like LCM is not a very happy bunny!

post battery check (actually even before if u have access to one) - hook up a scanner and see if the LCM is showing any errors..

or even to see if it responds..
My DDE kept doing that....

I removed the centre console, passenger seat and respective trim to run the data cable for the aftermarket stereo through the car. Since doing this I have had problems with the lights, I have disconnected the battery terminals for 20-mins, but still no luck
OK my plight so far

1 All the indicators, fogs, main, dipped & flasher lights all work externally, but not on the dash / gauge cluster inside, would this be just a connection issue behind the dash/ clocks as I’ve had the radio out? Or something more serious?

2 Both reversing lights are not working, checked the lamps (bulbs) and both are OK, put a meter across the terminals (both sides) and there is no power. I’ve had a look at the two internal fuse panels and there’s no fuse or relay for the reversing lights listed?
Because I have the centre console and respective electric plugs disconnected and out of the car at the moment, would this stop them working?? Is there a fuse, relay or switch anywhere I can further check?

I think its something straight forward with both of these problems, but finding them is where things get more difficult. All help and advice greatly appreciated.[/size]

I would disconnect the quad lock from the stereo, if the problems started after the stereo / head unit were installed and any other connections that you have made to new equipment, canbus box etc, as some of the connectors in the quad lock relate to the dashboard, binnacle wiring, you may have somthing dragging the voltage down, also there is a connection relating to the reversing lights Pdc in there too. Unplug the cable from the radio unit. You may have a short that is causing the problem

[jaynana]

sounds like you have a cross connection with the i/k bus wire, which is on the quad lock which goes into teh BM54.

the instrument cluster electronics (IKE) and stereo all communicate on the same bus network. i don't think this has anything to do with a disconnected plug or fuse or the sorts.. i think its just confused comms messages

disconnect the audio cable you must have fitted onto the quad lock and check if the lights are working properly.

i think everything will come back to normal! also i'm guessing the quad lock is the only place where you'd have hooked up the stereo into the car's wiring harness?

if that is what it is, next challenge is to find out what the rouge wire is.. i guess the config of the quad lock should help..

[Steamyrotter]

If i remember rightly, during my research ref Auto to manual swap the reversing light signal goes through your instrument cluster (for some silly reason!)

Looks like you may have upset the cluster electronics a bit..
This could be coincidental with I/Kbus as there is a fair amount of that going in there too
Have you disconnected the battery yet and let things settle??
The instrument cluster will do silly things unless reset

Any joy with getting to the bottom of this problem. I read your other post regarding where certain wires went from the head unit to the loom. Where did you get the info from to wire these in?
This could be your problem.

OK disconnected the stereo and battery, then connected all back up checking as I went, sucess all lights etc etc are working as they should. The once thing that isn't is the reverse camera.

As I have an aftermarket stereo do I still need to go via pin no.17 of the tv modules with a relay?
Can I not do away with the relay all together and just connect the reverse light supply direct to the camera in supply?

[Horizon]

Where did you get the wiring diagram? It looks to me as though this is a diagram to install a camera to OEM head unit. I would have thought the point of fitting an aftermarket unit would be to do away with the OEM tv unit.
I would have thought it was just plug and play.
I fitted a dynavin unit into my non satnav X5 and only had to connect the quadlock. It knows when I'm in reverse gear, as the PDC screen comes on, also when the handbrake is on so I can play DVD,s, although you can opt for that in motion. So I guess if it knows this via canbus, I would expect it to be plug and play with the reverse camera.
Did they supply a wiring diagram with it ?

so where was the fault? all it needed was a reset?

no. the picture you have is for the reverse cam installation into the oem video unit.

if you have an after-market stereo, you definitely do not need to hook it up as in teh diagram into the video module. you do need to feed the video output (usually teh yellow cable) from the camera into the video input (i'm hoping you have one) of your after-market stereo. plus there must be some mechanism of telling your stereo when you engage the reverse gear.. in order to switch the display  to the video feed from teh cam.

Yes I have run a video out lead from the camera to the head unit, on the rear of the head unit there is a lead marked AUX VIDEO-IN and another BACK-VIDEO-IN ? NOT SURE WHICH IS WHICH???
I run the supply to the camera off the reverse light supply, when this is selected would the video output from the camera switch the head unit when the reverse is selected (powering the camera)?
Do I need to have a relay in the circuit? Any ideas???
The leads off the rear of the head unit

[jaynana]

re which video - lookin at your photo it should be the back-video in.

aux video in together with aux-l and aux-r must be for an auxiliary media player connection.

re. how to flick the display to the rear cam input:
powering the camera alone wouldn't usually help (i think..).

u could of course connect it up, power the unit, power the reverse cam and see if it does the job on its own..


i would expect there to be some signal input to 'inform' the stereo unit to flick the display from whatever its showing to the camera input.

that's what we achieve in the oem setup with the relay and all that jazz.

isn't there another input to the stereo - like 'reverse light' or 'reverse signal'' or something of that sorts?
