Honda City ABS error - wicked problem

**frost2** · October 28th, 2018 11:48 PM

Hi Sir/experts/ experienced,

I am seeking some advise for my 2010 honda city.

So it started when my breaks (front left) wasnt working. I had it checked and it turns out the abs is not working.

I canvassed at honda and it would cost about 16k-20k to fix. So like any other matipid, went to banawe and got surplus parts.

I had the whole abs replaced for 5,500. It actually working well now brakes are all ok.

HOWEVER, after driving a few kms, the ABS warning light and break light turned on and this is were the wicked problem started.

I went back to the shop I got the abs, the checked and had it scanned and error is: 71-33 “right-front pr left-rear different diameter tyre malfunction”.

Actions taken so far:

I had it replaced by a new abs from the same shop but still SAME ERROR.

I had my tires balanced and aligned and still same error

I checked all tires are same size naman.

Guys at the shop didnt want to replace the abs sensor since it is not showing up as the error

Questions/help needed:
- has anyone had this error before? What did you do?
- is this common for honda city 2010
- any recomendation on a place to have this checked? Yung mura sana pero magaling.
- in case sensor talaga need palitan. Any reco where to buy, how much?

Thanks in advance guys, hope to get some clarity on my problem.

Balik casa. ABS not something I'd like playing around with...

I also have a 2010 city. Never experienced that issue.

If they already replaced the ABS pump and the warning light is still on, it may be one of the wheel sensors. Get your car scanned at a shop that can also “detect” faults with the ABS system, so it can tell you exactly what component is faulty.

Yes sir. Sira talaga, walang fluid na lumalabas kapag nag break ako.

Thanks for the reply, i got it scanned po sir. It said 71-33 FR or RL tyre diameter error. I am not sure what this error means exactly. I have the same tires size for all.

the abs probably compares diagonally aka fr-rl and fl-rr

front left - rear left
front left - rear right

im guessing comparator detects too much speed difference between the two sensors.

one sensor is probably defective or dirty

Interesting. Let me try having the sensors cleaned. Ty sir.

What stockengine said is correct. Could be just dirty sensors.

The ABS pump could have been clogged with dirty brake fluid. This applies to all cars. ABS or Non-ABS. You should flush the brake system when you see that the fluid inside the reservoir has turned black. You should be able to see through the bottom of the reservoir if the fluid is clean.
