ABS Light

Post by mjc9967 » Wed Feb 11, 2009 1:25 pm

Well things couldnt be too perfect for too long could they? :?

The ABS light has decided to come on from time to time. Once on it stays on until ignition off, then comes on again when it next feels like it.

Have tested ABS operation (lucky we've been having the snow and ice) - it works when light extinguished, does not work when light illuminated, as you might expect.

Apparently this version of ABS does not have fault memory or diagnostic capability. So, fault info is not stored anywhere, and even if light is on when car is looked at there is no way to ask what it is saying. There is no diagnostic plug for a box of tricks to provide a fault code, nor apparently can the ABS light be made to flash a sequence code by touching any wires together (something I had heard might be the case).

Problem is, it seems likely the light is being triggered by a very short momentary condition (and then once on it stays on until power down). Im being told the only thing to do is spend time examining every component, but then whatever the fault is probably wont occur exactly when that inspection is taking place.

Anyone out there know any more than this about diagnostics/fault finding for this? It would be really helpful to discover a way to just get a fault code out of the system somehow.

Thanks in advance
Mark

It's probably a faulty/dirty front wheel sensor. Mine sometimes throws up a warning light when the front left wheel goes through a deep puddle. After a restart it's always OK.

Wow Rich you are quick on the keyboard!!

Does what I say about lack of diagnostic capability compute?

How do you clean the sensors?

(PS sent you an email about coming for bits today or tomorrow)

There is a "Fast Check" box available for the ABS ECU but I don't have one and I don't know anyone who does. The usual method is to check the resistance of each sensor with a multimeter - typical looking for 1200-1600 Ohms.

ABS sensor cleaning is usually a case of unbolt the sensor from the hub (2 x 10mm bolts which will no doubt be tight) and clean it off with ta wire brush.. it's worth also cleaning the reluctor ring on the CV joint at the same time.

Sounds like its worth a clean to see if it helps thanks Rich

If not, do you know if the sensors are hard/expensive to get new?

Reluctor rings are new and shiny as CV joints renewed last month.

I think that mk1 and mk2 ABS sensors are the same - if so, they're available new from specialists like Rimmers and Best of British Rover - last time I looked they were £80.

Ta Chris but dont be too deceived - cars look a lot better wet dont they? :wink:

Still waiting for weather to polish it up properly, then the pic might be more accurate all the time!

Having seen Mark's car in the flesh, you'd have to be pretty demanding to say it doesn't look good.

More daylight pics and paintwork discussion

Post by mjc9967 » Mon Feb 23, 2009 1:32 pm

Went to my sister's this weekend and couldnt resist getting the camera out on her nice driveway with beautiful manicured evergreens around!

Image Image

Been a week since it was washed (see post on 16Feb above) and I feel these pics mask a few imperfections but also distort the colour - looks a bit flame red for my liking!

Image Image

I think its a combination of lighting/cloud cover on the day and camera quality, but mainly the paintwork condition. The previous post shows the car wet after washing, and thats the look I want to achieve full time, more of which later.

Image Image

This last pic shows the tattiness of the "ROVER" badge, the "820i" one is the same. Cant seem to find new ones so far - hope I can get them restored at some point.

Here are a couple of (non exhaustive) imperfection close ups:

First, a nice long scratch along the lower NSR door. You can also see a couple of small rust spots waiting to burst out near the bottom of the wheel arch. The rest is dirt and road debris.
Image Image
Second, drivers door looks like it stood beside an enthustiastic road gritter for some time! These spots are through the top coat, think it needs repainting. Also, drivers door handle been replaced with non matching colour, but again I think the camera did some of its own colour matching, reducing the effect.

About the paintwork generally, my previous experience only extends to washing with carplan shampoo and polishing with AutoGlym car polish, but I gather there's a whole other world of "colour restoration" and "car detailing" out there. I think I need to take a peek into this parallel realm if the car is to be properly presented! I want the real showroom look here.

It has plenty of micro scratches and swirls, and running your finger along any of it soon teaches you how a badger's arse must feel :lol:

The plan brewing involves clay bar and lube, meguiares paint cleaner, meguiares polish, and meguiares gold wax. Also on the shopping list are a decent variable speed polishing machine and a healthy supply of bonnets and microfibre cloths. Oh, and a good couple of full days in good weather and a nice environment (like the driveway in the pics).

Hopefully then the majority of the car will be really top notch, and painting can be minimized to a couple of small really bad bits. I think properly restored paintwork should also help colour matching and finishing too if painting does have to take place?

Probably be a few months before I can justify the money on some of this stuff (everything I want to use stacks up to over 100 quid!) and also get the weather, so I guess I'll just keep watching the "how to..." clips on youtube until then!

I'd love to hear anyone's tips and advice on this stuff if they've gone down this road already.

Cheers
Mark

The clay bar etc. route is well worth the effort it really will restore the paint work although best to deal with the chips first. I did mine even thought it was silver the amount of muck that came off was amazing, you'll be glad you did.

As well as listning to Rich C (above) you should contact John (47p2) as he is over a hundred years old and is a dab hand at making cars look like they're wet they are so shiny. And ask Neo, too. He spends so much time polishing his Coupe (he's frightened to use it in case it boils over) it's a wonder there's anything left of the paint on that bodywork.

As regards some nice (NEW) badges...I'll have a look later in my box. I have dozens of new Rover scripts -they come in subtlely different sizes!- and , I am sure, a new 820i badge.

I'll report back later after a cuppa tea and a hot dog.

I can't find my way into my units as the power is off. I'll have to look tomorrow. Sorry.
