Sprinter 311cdi=abs problem?

[cobe]

Hi guys,my son has a 311 sprinter,this started "he says whilst going over some big bumps,the traction light came on followed by the abs,it was intemitent but has now settled to permanent.also I have looked at other posts on here about abs,can you tell me if when you talk of wheel sensors are you refering to the sensors on the pads or as on the old ford cossis a seperate sensor for the abs,thanks in advance.

Hello, its not the pad sensors, it is the ones in the hubs for the speed signal

Thanks malcom,I have put new discs pads and sensors and it did not cure it so now understand why,I will have the lot off again and check all the hubs,can I ask is it a major job? thanks.

You have the sensors in the hubs nothing to dismantle, first just make sure that they are all pushed home.

I do not have any pics for the sprinter, maybe one of the other techies will come on

Thanks again malcom,he's only had it a short while swaped it for his old vw35,and i'm just finding my way round it,i,m 61 used to have 8 wheeled tippers,so i'm ok on the spanners just the new tec stuff makes me scratch my head a bit,any way thanks again for the help.

abs light

Hi all,just before I try sorting this out for my son,can anyone tell me if the items that i have read about on here for merc cars are relevent on the sprinter ie brake switch,brake bulbs out,and the voltage box etc just in case its not a sensor i can check the other stuff to,thanks Mike.

It's not a sensor, unless you've broke a wire to it and even if it is they are a swine to get out. Yes to the other stuff as they are prone to the similar faults. Before you dive in disconnect the bat and leave it a while it may clear a fault code, some have diff locks fitted and are prone to coming on when a whell leaves the ground as in your case, star would show it up but as you aint got this then try the bat first.

The last guy on here with a Sprinter and a seized caliper dislodged a sensor and had the ABS lamp on till he pushed it back in

abs problems ?

Thanks again,i now have a list of things to check,I will try the battery disconect first then work my way through the simple things before it goes to some where to read the codes,trouble is he's like a dog with two tails with the new van plus he has had a lot more work since he got it,and I am haveing trouble getting him to stop long enough to check it,thanks once again will post back when we find the fault. Mike.

Malcolm I think that would be a pad sensor, which is attached to the caliper, the abs sensor is inside the back of the hub and you have to remove the hub to get what acess you can to it. I've only ever changed a few, although loads of axles, you have to remove/replace them when removing the axle and every one I've done is seized solid into the axle. They use a clawed retainer to keep them in place and these bite in, a bit of salt and water works a treat.

abs problems?

Hi all,I thought after the advice you have kindly given I would ring round my area to see how much to have the codes read.All roads seemed to lead to SG Smiths main dealers,the service person carmly told me £100.00 plus the vat "but" if it could not be done in an hour it would be more,how much more i whispered,difficult to say fault codes can be very difficult to read some times,"but" the good news is we could fit you in quickly as we are quite slow at the moment, Humm I wonder why? but I will say she was polite.

abs problems?

Hi all,just a short update for those interested, phoned another branch of SG Smiths,what a difference! no problems sir very easey £45.00 plus vat,?? Quality it's only 10 ish miles from the other one.

Hi all,have just tried the disconnect the battery,all lights went out,took it down the road (very wet) abs worked fine but after test all lights staid on again.have checked brake stop lights "all good" so would guess switch is ok,I guess its fault code time next week,will post results when known,thanks all.

Where are you based?

(sorry if you've said and i've missed it)

abs problems?

Hi cnics,I'm in sutton Surrey,I have spoken to a very friendly van sales place and he has given me the number of the guy he uses(apparently it is quite common on sprinters he buys in) so I will phone him monday,but any info would be appreciated thanks,Mike.

Try fitting a brake switch, they are about £11.00, even if it's not that it will prevent a fault in the future. They are easy to fit, remove the coin holder and look through there, press and turn the switch anti clock wise after pressing in the clip and disconnecting the wire multi plug. Again disconnect the bat and reconnect, it clears the fault code but does not remove it from the history. It's probably worth removing the stop bulbs checking they are clean and good contacts, if you've got two news ones change them, as bad contacts also give you funny fault codes, simple quick test and may save you a few bob.

Thanks dava,I will try the rest of the simple stuff before i get the codes read,they do not make them simple now days humm! Mike.

 

[cobe]

Just a quick update phoned the indie number I was given by the van sales place,£35.00+vat wed this week so at that price i'm going to wait till I get the codes before I go any further,thanks all Mike.

problem abs?

Hi all,Had the codes read today on the star machine and they were nothing like I had in mind but no matter,first fault was that the glow plug on No1 cylinder had failed (food for thought for latter)On the abs side fault code C1011=valve relay undervoltage. Figure Legend-A2 abs control unit, F6-abs fuse terminal 15, F6-abs fuse terminal 30, F7-abs fuse terminal 30, J10-con sleeve circuit 30, J31-con sleeve circuit 16, J332- con sleeve curcuit 15, W7 ground point in engine compartment, W27-ground point for abs. Possible causes of fault--Fuse F7 is faulty, Line A2.1/6-J16 has -//- Line A2.1/6-W27 has-//- Finally Control unit faulty,I will be honest people the only thing I understand on that is "Ground" "fuse" and control unit, so on getting home I looked for fuse 30 and there is'nt one, fuse 7 is heater motor,: so nope, Ground = the earth so disconected batt as the test also had batt read of "11.80"? ? cleaned terrminals reconected,disconnected control unit main loom as I know the dealer had steam cleaned the engine before we got it so may be water ingrese etc looked clean etc refitted had agood look and pull at loads of connecters thats it! put the bonnet down and drove it back to my son, he presto no abs light minfull I had disconnected batt I waited for them to light up again nill lights so tested brake hard,no lights drove all the way back,no light spun the wheels over speed hump I had lights but went out as should,parked restarted no light??????.Could any one explain the read out please or was it just an earthing prob,gratefull for all input thanks Mike.:

A low battery voltage could have caused a starting blip every time you started as the van had been standing, the ABS light will be one of the first to come on
