My 53k kms old Figo's ABS light is on since the past couple of days. I took the car to Shreeji Ford at Thane for a free pre-monsoon checkup. The mechanic jacked up the car and rotated the rear right wheel. He told me that the light is on because the rear wheel bearing is kaput.

I haven't got the car fixed till now. Wanted a 2nd opinion from people here.

1. Would wheel bearings wear out in 53k kms ?
2. What connection does wheel bearing failure has with ABS sensor ?

I was also told that some magnet inside has failed which is also causing this light to remain on. I did not understand what he meant. Any light on this magnet part ??

Well, there are cases where they can and many cases where they last more as well. 53,000 Kms makes a good case for a wheel bearing to go kaput as well.

2. What connection does wheel bearing failure has with ABS sensor ?

From what I understand, NOTHING! If that is the case, you will have to replace the ABS Sensor every time the bearing goes kaput!

Ideally, It is a typical wheel speed sensor and a ring with teeth that work together and the signal wire passes information to the ECU on the wheel lock (one wheel rotating faster than the other) and the ABS kicks in.

Last year one of my friend faced this problem in his Honda City and the car was diagnosed to have a fault with the wiring due to rat bite.

Ask your ASC to Plug the OBD Scanner and look for the exact reason but do check all the associated wiring as well.

My 2010 Swift Vdi ABS with 67k on the odo has the same problem of the ABS light coming on intermittently. Showed it to the ASS, Sai Service in Parel, and they're telling me its a faulty sensor on one of the rear wheels based on the error codes. They do not have the part, but have ordered it. Cost of part is 4750/-, labour extra. Any ideas if this is reasonable. Conversely, a friend had the same issue on his Polo last week, and he has paid Rs.4300 all inclusive(part + labour) for a new sensor. Seems like Maruti is getting very expensive. Any ideas mates?

Part cost in eBay is almost the same.
There are certain parts Suzuki will be on the costlier side. In this case, VW might be using the global part (sensor) across many other models in other region too. This make their intake order quantity a fairly larger number and thus the price is on the lower side. With MS in India, we have very fewer models / vehicles with ABS and the lower intake quantity results on the higher price (though I'm not very much sure about this, it is general thumb rule)

Hope you must have got the wheel bearing changed. To answer your query,
1) Depends. There are many contributors for wheel bearing failure (accident, manufacturing defect, impact due to faulty mating parts,etc)
2) It's nothing to do with the ABS sensor. ABS encoder is fixed inside the wheel bearing. A faulty wheel bearing may damage the ABS encoder, resulting in warning lamp indication. FYI, ABS version rear wheel bearing for Figo / Classic should cost around 1500 INR

Snap for reference. The magnetic encoder will be placed on onside of the wheel bearing (normally towards vehicle inside)

Part cost on amazon is much cheaper at approx. Rs.2400, but anyways, did the work at SAI service itself. Part cost was finally cheaper at about 3700, plus 899 for scanning plus 450 for labour plus taxes, making a grand total of Rs.5200.

SAI service took 2 days to complete this simple replacement, due to the non availability of the sensor, and finally also, I had to sit with the mechs to ensure that they completed the job. Was also upset at the fact that they never tried cleaning the sensor before replacing, so I have my doubts about whether the sensor was really kaput or could have just been dust causing the snafu. I have cleaned and kept the old sensor, just incase. Anyone needing it, please PM me.

Anyways, happy that the car's working fine now. ABS light has gone off now, and the brakes are working fine.

Cleaning will not workout (everytime) with the magnetic encoder sensors, it is wise to replace the part. (worst case they should have checked for any loose connection)

That's a daylight robbery. Close to 1k INR for a single scan? I hope the cost of instrument will be recovered from 1st 10~20 customers

Guys
one of my friends has reported a similar problem as you have mentioned above. He has a FIESTA 1.6. Recently he went over some rough roads and at a particular stretch there was a deepish gutter the car went down with a loud thud. While no physical damage was noticed, the ABS light has come on since this incident. Could this be a case of some loose connection or something else ?

I doubt the same. This requires a step by step fault analysis. Take it to a FNG who could spare more time with the car. Check in this sequence
- OBD check
- loose connections
- wire / sensor damage (simple multimeter is sufficient)
- And finally the wheel bearings

Does anyone has any idea about the life of ABS sensor and approximate cost of replacing it on a Hyundai Getz.

I have Hyundai Getz GLS ABS 1.3 (2005). The ABS light came up around one month back. When my dad took it to hyundai service centre in Ranchi, the service advisor informed after initial checking that the sensors life is over and has become faulty. We need to replace them and the aproximate cost of the work would be around 36000 . This amount seemed pretty too much. So I am driving the car with ABS light on all the time

Since i drive at generally below 100 speed, i thought it won't be a problem. But i noticed that the brakes kick in quite hard after a certain point. Given the bad road conditions in Bihar/Jharkhand, it feels like the tyres are skidding in case of hard braking. But i don't get the same feeling when braking on my other vehicle (Wagon R). Is this because of ABS or just psychological.

Step 1
(1) Find out which sensor is faulty - there are 4 speed sensors at each wheel.

(2) Find out the part number of the faulty sensor.

(3) Order the part from EBay. There are plenty available (price ranging from 40$ to 125$).

(4) Even with shipping and duties, it would not cost more than 5000 - 8000/- or so landed. Might be even cheaper if you look around a bit.

(5) Replacing the sensor at an FNG should not cost more than 500/- at the maximum (it involves only disconnecting two ends and probably removing a bolt).

36000/- is a ridiculous quote to put it mildly. Hope this is useful. I would not recommend driving around without ABS even at speeds below 100 kph.

Wheel speed sensors are supposed to go on for the life of the vehicle unless there is a wire cut or so. Ideally there should be no contact between sensor end and encoder, which means there is no wear and tear (unless there is a problem). Hope this helps.

Thanks for the quick reply Viju.

But i just have one doubt what if the sensors are not faulty and the problem is with
1) The control board or
2) Sensors are simply dirty (since it is an old car) or
3) Connector problem or
4) The Motor

If anyone knows how to check for fault codes or anyone with info of a reliable workshop in Patna, Ranchi or Lucknow for ABS system, that would be of great help.

@Eagleeye

The sensor can fail right when you take it out side the service station. There is no guarantee of a sensor life while as long as you are covered under warranty they will provide free replacement.


There is one another occasion when this light comes up. When your battery is very weak Happened to my swift both times we had to change battery.

The case of missing the error in first inspection is quite normal. The error message even in my vag said it was ABS fault. There was no clear indicator of what was wrong with the ABS. The easiest way to find was to replace a sensor from another car and eliminate the sensor.

The error messages are mostly generated by expected voltage vs actual voltage received in most of these circuits. And also the wheel speed sensor itself may work on voltage concept which means for any thing from wiring issue to actually failure of sensor the system basically shuts down the ABS and generates the common warning.

And ABS failure is generated for a whole bunch of circuit that on cursory look(the first inspection) it may go unnoticed as a specific part failing. So dont worry about how it got missed for its an elimination job with respect to finding an error with ABS.

May be the new age car cpu's are equipped with more detail at circuit level to give specific error. But i doubt it as its not only waste of time but waste of investment in that kind of technology for diagnostics .

This is based on my personal experience with my Jetta and the final diagnosis was a rat bite imagine it took 3 days to eliminate all other cause.

- Dirty sensor,
- bad wire
- Fuse
- Bad circuit by checking each and every circuit inside the car which is when they found that rat bite hidden inside. It was small yet significant to alter voltage.

I still remember not soldering a o2 sensor and merely connecting with hands. The sensor sent signals so erratic that at 26deg the car was cooling like -10

The best place to find out the exact error code is an authorized Hyundai workshop. Multi-brand garages may / may not be able to pin-point the exact faulty part with generic diagnostic tools.

Your dealer cannot be vague about some sensor's life coming to an end. Ask him or any other Hyundai dealer to find out the specific faulty part and what had happened to it.

If it is anything related to the ABS unit (be it ECU, motor, pump etc), you have no choice but to replace the entire unit as such (which will be usually a huge expense). If you are lucky and it is just one of the wheel speed sensors, it might turn out to be economical. Yes, dirty sensors are a possibility, but there is a higher probability of a broken sensor wire.

Hi All

Greetings!

I am having an SX4 ZDI. It has done 70K+ Kms. Its battery has been changed with a new one in June2016. It has been nicely maintained with regular service, engine oil and filter changes at every 5K Kms, Coolant change at 20K, daily running for 90Kms, with generally no issues till now

Since last few days some times the Brake Light and ABS indications come ON together intermittently for couple of seconds and then go off. While they are ON, the steering becomes hard to move, this happens only for couple of seconds, after which everything is normal again.

The second time, these two light indications came up when used the horn, during that, the horn blew with very less sound as if the battery is not supplying power to it, again this happened for couple of seconds

The third time it happened while switching ON the head lights in traffic, during which could not feel the symptoms as the vehicle had just started to move and the Brake light and ABS indications went off immediately.

I am generally quite good at identifying electrical issues and I feel during the time these two lights are coming up, something is drawing much more current than it should, may be some thing is getting short/misbehaving.

Please advice, Thanks

[BLACKBLADE]

If the ABS light and the brake system warning light stay on, or come on simultaneously when driving, then there may be something wrong with both the rear brake proportioning valve function and anti-lock function of the ABS.
If one of these happens, have the system inspected by your SUZUKI dealer. If the ABS becomes inoperative, the brake system will function as an ordinary brake system that has no ABS.
