Update...

 

Right then, where do I start...

 

Decided to clean under the wheel arch, only to find that a bit of the arch collapsed due to rust, and possible damaged the rear wheel speed sensor after cleaning out the years of gunk.

 

VSA & ABS lights came on.

 

Had a diagnostics, and got a new sensor, Halfords, £173 fitted, as apposed to Honda's £160 just for the part.

 

Picked the car up and the Warning triangle came on, then the VSA light, grrrrrrrrrr... back to Halfords, did a new diagnostics and now they tell me something about ”Sensor Logic Failure” AAAARRRCCCHHHHHHHHHH

 

:angry: I SHOULD HAVE NEVER CLEANED THE WHEEL ARCH. :angry: 

 

oh and they cant do anything about it as the are not auto electricians.

 

I only wanted to clean the arch and now its body work, spray painting and electrics..... Im starting to think, I should push it into the river.

 

 Ok not really, I love the car, but OMG. :(

Sounds like Halfords should be giving you a full refund.

Has the ABS light gone out?

any idea what they used for the initial diagnostics  ?

 

and I definitely don't understand the "auto electricians" thing, the codes should indicate the issue

and I have a Honda HDS and live 50 miles west of Peterborough if that helps ;)

If it wasn't the only wheel arch you cleaned it could be one of the other sensors (or all four.............................)

Hi everyone, it's a petrol. I only checked the right rear wheel, so no others should be at risk... Fingers crossed.
As I'm not working yet, (recently relocated to Peterbrough, but promise of a job on the horison), I'm holding back, I have decided that when I am earning again, I will take my baby to Honda, for a complete check and to hell with the cost. I have also approached a body shop for a quote on checking the wheel arches and repairing and spraying them and other minor marks.
The guy at Halfords did mention there was other faults and I got the impression he wasn't too confident with what he was doing as he kept seeking advise, and as they charge £49 to diagnose, I insisted they check again, but they said I need a auto electrician.
So I am gonna wait for now, till I have some cash coming in.

Hi
It was a friend of a friend that did the initial check for me, as he was doing it as a favour for a tenner, and he came up with the first fault, which led me to taking the car for the new sensor, I knew this would be accurate as I was messing with the rear wheel area cleaning out years of road muck, and I was quite rough. After the new sensor, Halfords only checked again, as I went back to them like I mentioned, but then they said they couldn't help anymore.... But I'm thinking I should insist on another mechanic.
If I don't manage, I might just take you up on your offer, I'll let you know.
Cheers for the support.

Sensor logic failure means the vsa reset procedure needs to be done, either with a Honda hds (or compatible) scanner or the "paper clip method" which is documented on here.
Your probably getting the 84-01 error code. I've used the paper clip method and can tell you it works as long as you clear the abs code first (also with the clip)
I've also used Honda to do it before I realised it can be done by myself.

Edit - you don't have to use a paper clip any suitable gauge of wire will do

Vehicle diagnostics is only as good as the person doing it (and that goes for Honda as much as Halfords)... as already mentioned, our cars have built-in diagnostics that can be initiated by shorting certain pins on the diagnostics port (4 & 9) and simply watching a light flash. It really can be that simple but, importantly, it's how the technician fully interprets the reported problem that really is the key thing.

However you'd be far better off taking up Freddofrog's offer... he has his own Honda Diagnostic System, the official Honda workshop manual and a lot of experience with his Accord (I've even let him run diagnostics on my diesel!).

Does Acura/Honda USDM and EUDM have the same OBD2 port?

I'm not familiar with US variants, but the OBD port shown/highlighted in that YT clip looks exactly the same as my UK model.

If your after the port numbers look closely at the diag port with a torch, you can just make out the numbers for each pin

OBD is a worldwide standard so the pin numbers will be the same.

 

Many of the videos confirming the dashboard flashes for ABS are from the US (or show LHD vehicles) so I would suggest wherever the car is, the plug in diagnostic is the same.

Has the ABS light gone out?

 

+1 why not pursue this with Halfords head office first of all.
