vito 110 cdi dash lights.

[Raw40]

Hi all, I'm new to the forum bought a 2001 Vito 110 CDI earlier this week, had a number of faults, broken O/S/F coil spring, N/S/F wheel bearing and required some loving care and attention Brakes, Service etc. one problem I'm having is the instrument panel lights odometer, clock, and backlight are staying on permanently when the ignition is switched off, the battery was flat yesterday wondered if this would cause the problem any advice would be appreciated.

Hello and welcome, cant help you that much, but the dash lamps will drain the battery almost over night.

I do not know the model very well, but if like the cars, A SAM unit could be faulty and the normal way to check is an ammeter in series with the battery and fuses pulled to see what is casing the fault

Hi televison,

Have talked to the "trader" that sold the van he's trying to convince me that the dash lights are designed to stay on in this manner, doesn't sound right as you mention I would have thought they would drain the battery fairly quickly.

No they are not designed to stay on permanently.

Thanks Alan for confirming it's a fault now comes the difficult part curing it

Make sure the fog light switch is in the off position , an alarm sounds if it is not and you withdraw the ignition key . The dash lights remain on if you do not turn the fog lights off. This is meant to be ,I dont think you have a fault

Have checked the fog light switch doesn't seem to be doing anything no front fogs on the van but the rear doesn't seem to be working at all. tried tracing the circuit the clock, odometer and the backlight go out when the hazard warning fuse is removed the instrument housing makes a weird clicking sound until the fuse is replaced any ideas?

Front fogs are built into the headlights and will only work when the headlights are on dipped beam ,for the switch to be in in the off position it is midway, down is front fog only and up is front and rear fog .they will only work with the headlights on (front and rear) if you put headlights on high beam front fogs go out also ignition needs to be on for fogs to work . If you dont turn the fogs off even though you have turned the headlights/sidelights off and remove the key the dash lights remain on with an audible alarm if the drivers door is open .Close the door alarm stops but dash lights remain on if the switch is not in the midway position . It's to prevent you from driving around with fogs lights on unecessary ie next time you use the vehicle ,Unlike female fiesta drivers who drive around wih them on 24/7/365. The clicking noise your hearing is the indicator relay .THE HEAD LIGHT HAS TWO BULBS ONE IS A SINGLE PIN THIS IS YOUR DIPPED BEAM ,THE OTHER IS A 3 PIN BULB WITH TWO FILAMENTS, THIS ONE IS YOUR MAIN BEAM AND FRONT FOG LIGHT .

If the contacts are worn on the indicator/headlight switch it causes the front fogs to flash momentarily and eventually stop the front fog lights working altogether and it is a common fault . A new indicator/headlight switch will be required , cost around £70.00

Also is the orange indicator light working on the fog switch when the fog light switch is in the up position ?

And also if you unlock the vehicle the oddometer and ambient temp/clock lights come on , WHEN YOU DEPART THE VEHICLE THESE SAME LIGHTS REMAIN ON UNTILL ABOUT 30 SECS AFTER YOU LOCK UP THE VEHICLE . However if the fog light is not in the "off" position the dash lights remain on .The clock is multi function (ambient temp or clock) depending on what you have selected .

From what you are saying here I think your vehicle is fitted with the service assyst computor, ie tells you when the next service is due and also tells you the engine oil level. I think you should read the vehicle handbook if you have it if not I have one here and can scan the relevent pages and post on here or E Mail to you if you've made your E Mail address available.

Hi and thank you for such a comprehensive reply. The orange indicator light on the fog light switch is not working at all have tried with the headlights on and the switch in both up and down positions.

The vehicle is fitted with service assyst the multifunction display flashes when the ignition is switched on shows three spanners and a mileage then reverts to the odometer reading after about 15 sec.

I have another problem/fault with the central locking when I lock the vehicle from the drivers door the central locking, locks and then unlocks immediately, with a second turn of the key the central locking system locks, unlocks and then locks and remains locked. you mention " also if you unlock the vehicle the oddometer and ambient temp/clock lights come on , WHEN YOU DEPART THE VEHICLE THESE SAME LIGHTS REMAIN ON UNTILL ABOUT 30 SECS AFTER YOU LOCK UP THE VEHICLE" . is it possible the display lights staying on might be connected to this central locking problem/ fault.

I have the owners manual and will have a good read through it tonight

thanks once again for any advice

regards Richard

I will try and check, but my info is limited on these.

Putting the fault into car terms, it looks to me as though it is not going to sleep,if fitted. All MBs light up the dash on unlocking, if the car is not driven or a door opened, they will lock again and the lights go out. It seems that the car does not want to lock, and you have to force it to.

If you have just had it serviced you can reset the service indicator yourself ,the hand book tells you how to do it .
On your dashboard you should have a switch for the door locks ( ignition needs to be off for this to work) this is your dead locking , press down for rear doors ,press up for front doors or press twice up locks them all except drivers door . The reason your remote is not working on the first press of the remote it is scanning to see if any doors are not locked hence the need to press the remote button twice your indicator lights should also flash when you lock/unlock using the remote when you lock the doors either way the (switch or remote) fuel filler flap locks/unlocks as well .

Getting back to the fog light switch , was the ignition on and or engine running if so then the switch is probably knackered as the little orange light in the switch should be on . This would be an MOT FAILURE if the indicator light and/or rear fog is not working .

Firstly check all your fuses (located under steering wheel) also check the rear fog light bulb , if OK THEN REPLACE THE FOG LIGHT SWITCH UNIT . This switch unit also operates your headlamp height adjuster (thumbwheel) this is not an electrical function but operates by vacuum .To gain access remove the air vent (just pulls out) next to this switch and if you need more access to it remove the side plate on the extreme right side of dash (drivers door open) . The fog light switches have been known to be troublesome but not usually . This little switch is electrically interconnected to the fog lights,the indicator switch, the ignition, the courtesy lights (front) dash lights and door locking .

I have used these vehicles with a special taxi conversion for the last ten years and pretty much know them inside out .The two I have now having covered 800k miles between them .They are a good work horse , reliable economical and relatively easy to maintain regular sevicing is the key to success with them . How many miles has yours done ?

As someone has said, that is a sign that one of the doors are not locking. The wiring that goes between the door and the A post gets brittle and breaks, you might find that the electric mirrors start to play up and passengers windows won't work from the drivers side etc.That is worth checking.

On the rear sliding doors there is a three pin contact on the rear of the door, clean them and the contact on the B post, that will help the locks on the rear central locking to work.

this is normal on the vito's.
as said before check wiring loom from door as this breaks down had a similar problem with my vito taxi last week replaced this loom an that solved my problem

thanks all for the advice I'm going to spend sometime this afternoon having a look at the faults I'll report back later on anything I find or solve.

Hi all, bit of an update have found the N/s sliding door central locking actuator is faulty, sounds as if the motor is running but doesn’t move the pushrod. Both of the front door interior light switches/ plungers had been disconnected when reconnected the interior light is working but I now have a warning buzzer on the instrument panel when I open either of the front doors the instrument panel lights are still on permanently. I assume that this as in other vehicles is a warning that a light has been left on? The orange indication light on the fog light switch now comes on when the switch is in the up position doesn’t illuminate when the switch is in the down position, rear fog light is working but the front fogs don’t work with the switch in either position. All of the lights on the indicator stalk side, dipped and main beam all work.

Any ideas welcome?

Hi quick silver the van has done 126k sounds as if yours have served you well thanks for the advice so far.

 

[Quick Silver]

Glad to hear , your now getting some where ! The buzzer is telling you that the lights are on , so if the lights are actually off and the dash lights are remaining on it is telling you the front fog light switch has been left on so you now have to check cicuitry between fog light switch and the indicator/lights switch (stalk) and then check both switches for function and o/c (open circuit) .The lights including fog lights all work with ignition off but indicators don't. I would start with the fog light switch as its the easiest to check but my moneys now on the indicator switch as these fail regularly and yours has done about the right mileage for excess wear on the contacts which affect the correct function of the fog light/switch and fog lights themselves .Fog lights work front and rear only with headlights on either or front/rear or rear only.Hope you can understand this and good luck . Cost of indicator switch is around £70 from MB YOU WILL NEED THE VIN NO AS DIFFERENT VARIATIONS .

Afterthought ! Point vehicle at wall , engine running (best done in dark) close proximity then turn on side lights ,then head lights then full beam then back to dipped now operate fog light switch (front/rear fogs on position) check light pattern as you do this (should be able tell whether fog lights are working by doing this ,then operate indicators with the fog light switch in the off (midway position) check that there is no momentary flash of the front fog lights and momentary change of light pattern . Post back your findings !

Ok have removed the fog light switch checked the supply from the indicator stalk, switched live from is there on spade number 1, I have a permanent live on spade no 7, have bridged spade no 1 to 3 on the connector block and the front fogs illuminate so I guess that proves the wiring and bulbs are ok. Then checked the switch itself for continuity between spade 1 and 3 with it in the front only position and it’s ok. When I reconnect the switch and switch to front fogs they don’t work? I’ll try and figure out all of the other connections on the switch this evening might even dismantle it and have a look at the internal connections.

Most definately the indicator stalk/light switch , Really common fault and fools everybody remember front and front/rear fogs only work with headlights on . It will be worn contacts internally.(TWIST SWITCH FOR LIGHTS)
