I had an issue with my ABS/ VSA on my fn2. First of all the problem was intermittent with the ABS kicking in at slow speeds <10mph.
Then the ABS/VSA lights appeared on intermittently. The fault was diagnosed as a faulty “Rear Right wheel speed sensor open circuit”
A failed attempt to clean the sensor was attempted first but to no avail, so unfortunately the new ABS sensor was purchased from Honda!! £130! In this instance part number is: 57470-SMG-E02
So new part was purchased so I thought I would make this guide incase anyone else has this issue. The change took me around 40mins all in.
Firstly jack car up and secure with an axle stand:
Remove the calliper and carrier, at this point remember to loosen the locking studs on the disc. The calliper can be removed without having to release the handbrake cable. Also at this point the sensor wire can be removed from the chassis, there are 4nr clips.
Secure the calliper so that it is not hanging and putting any strain on the cables and remove the disc. This will expose the hub, ABS ring & the sensor. Here is a picture of the failed culprit.
I gave the sensor a good coating in some releasing fluid/lube, but this really needs to be smashed in order to be removed. Before attempting to hammer this out, there is a 10mm nut on the back of the sensor which will need to be removed, be careful as it will be corroded and can easily round. I used a punch slightly smaller than the diameter of the sensor plug hole and hammered away, being careful to not touch the ABS ring. I had to use a fair bit of force and the sensor will break up.
Once removed I have the hole a good clean and a file to remove any corrosion build up prior to fitting the new sensor. I also gave this a thick coating of copper slip to aid install of the new sensor. When fitting the new senor be sure to make sure the 10mm locking hole matches up on the rear of the hub. I pushed the sensor as far in as I could by hand. After this I attached a set of small mole grips to the sensor body and tapped away lightly with a hammer until it was home.
.
Next is just a matter of refitting the wire and clipping the cable tie blocks onto the chassis of the car. Take care to put these on the right way as to not stretch the cable.
Reverse procedure for putting the disc & calliper back on.
Fault was gone instantly and didn’t have to unplug battery or have any codes erased.
Hope this is of help to anyone with this issue.
