| Wheel bearing change upsets disco - Solved |
|
Having just had the car in for a service I decided to start work on some of the faults picked up, starting with the wheel bearing (which I had pointed out to them)
A fairly straight forward job, including servicing the brakes which they had clearly neglected to do.
Did the job and started to drive off, my dash looks like a christmas tree, no HDC, no special programmes, park brake fault, suspension fault and no speed readout.
Plugged in the IID tool to see if that would give me any clues
In the BCM I have 9 faults that keep coming back
B1B02 - Low frequency coil
B1B69 -12 volt supply circuit
B1B70 Local interconnection network bus circuit 2
B1C26 - Pedal motor feedback circuit
B1c82 hedlamp washer relay circuit
U0155 lost communication with instrument cluster control module
and one for the seat and 2 for the steering wheel tilt and reach…
Parking brake
U-0122 lost communication with vehicle dynamics control module
Transfer case
U-0128 lost communication with vehicle dynamics control module
U-0122 ..as above
Vehicle dynamics
C1A91 front left wheel speed sensor circuit
With it being that bit cooler and darker I thought I would put the battery on charge while I worked, appart from the end failure the whole thing was fairly straight forward, helped by info on this forum.
Once again I turn to the forum for help, what to do next??

That many issues point to low voltage, so get the battery tested before spending any money.
Have you reset the faults? Do they come back?
What did you charge the battery? If not a ctek, try and get hold of one for a few days... flickr

You could also try a hard reset... flickr

The wheel speed sensor will cause the majority if those codes, did you damage it when doing the bearing or have you not reconnected it correctly? Is the driveshaft seated in the new bearing correctly as if it isn't the reluctor ring won't line up with the sensor. Re trace your steps and check everything

Hi Dave,
Thanks for your thoughts, I did use a CTEK and the battery was indicating fully charged at the end of the day. I used the IID tool to clear the faults which all came back almost instantly.
It was a bit quirky driving without a speedo, and surprising how far I got before realising it wasn't working,
May be unrelated but I had the DSC kicking in a couple of times when it really shouldn't have this morning before the work.
Thanks TomTom
I used the bearing nut to pull the drive shaft back through, there didn't seem to be any complications, if it was just the reluctor ring would that not need the vehicle to be moving before it would throw up faults?
With all the 'lost communication' I wondered if something had become disconnected, I also checked the brake bulbs are all working

Sounds like the symptoms I had when the brake pedal switch failed.
10 min job and as cheap as chips from Advanced Factors.
Worth doing anyway and may solve it.
The bearing change could just be co incidental?

Where on the vehicle does one find this switch?

Coincidence is a possibility, but the above is pretty specific to the area where I was working
It's all a bit of a poor end to an afternoons effort

Its under the brake pedal at the top - have a search I think there's quite a bit about it on here.
but yes looks like a height sensor issue!!
Bummer.

You could try raising and lower the suspension to off-road and access a few time.
I've read on here before that that can sort out random issues, especially as you've had it on the jack... flickr

That was my first thought, but that part of the car seems to have shut itself down.
It has worked for me in the past, DSC was going nuts on a very regular basis and driving me potty, running through the height a few times cured it.

Does the iid give you live height sensor readings? flickr

It does have that capability built into it, yes.

Do they show anything untoward?
A hard reset might be required to reboot everything, then clear the codes and see what happens. flickr

DSC engaging and the problems you are having point to a wheel speed sensor, maybe a coincedence or you've trapped a wire or broken the sensor. Or it has just failed. You guys are gonna be busier than a test bench in a plunger factory!

If you're speedo is not working it points to a wheel speed sensor that has failed and those errors point to that.
