    Hi All
    Just wanted to share a VSA/ABS light illumination that occurred last weekend.

    After owning the Accord for 2 years the dreaded VSA and ABS light illuminated together the other day including the message on the dash to check ABS and VSA system. It occurred after helping my brother move out and carried a lot of his stuff to transport to his new house.

    On the way there the VSA and ABS light illuminated for the first time. Once we arrived we unloaded the car and rested for a few hours, and then we drove back. Both the VSA and ABS light went out as normal upon engine start up.

    The next day I drove to work, a few minutes down the road the VSA and ABS light illuminated once again.

    Then on the commute home the VSA and ABS light went out as normal after a few minutes up the road.

    Since this day it hasn’t come on since. My thinking was that the car didn’t like the all the extra weight of the stuff we hauled and perhaps it was uneven with more weight on one side of the car perhaps.

    I have read several threads that the ABS modulator on the diesel model can be troublesome as they are made by Bosch.

    My modulator’s part number is: 57110-SEF-E610-M1 which is listed as an early version and part of the suspected faulty batch.

    From what I gather it could be one of two things. Either an ABS sensor or the VSA/ABS modulator pump.

    First thing is first, although the warning lights are no longer illuminated. I should ideally get the any fault codes read.

    I have a Foxwell NT630 ABS/SRS specific code reader which I bought relatively cheap last year on ebay. Registered and armed with the latest updates I gave this a go.

    20151220_143900_zpsa9m5tw3g.

    With this device connected I specifically scanned the ABS/VSA system which it was happy to do.

    20151220_143357_zpsad7uf275.

    The ABS/VSA system located

    20151220_143402_zpsmib0sdai.

    Once located I selected to read the codes

    20151220_143508_zpsfpllzzrl.

    ABS/VSA related codes



    20151220_140135_zpsy4pgtjxl.

    The car has currently no MIL’s illuminated so the ones it has found may be old ones which have been stored. This is the first time I have scanned the car with a reader.

    Nothing there with regards to the 66-1 modulator fault or any indication of any ABS sensor fault.

    I decided to clear all the faults, the system told me to turn the car off and then on.

    Once this was done the procedure was complete. All fault codes erased.

    With this being the first time using this bit of kit I also scanned the OBDII system and it detected the VIN and ECU serial numbers etc.

    Also a few other details below.

    20151220_143037_zpsz9ca5icf.
    20151220_143049_zpsfy2uyfdu.
    20151220_143055_zpsbwz9oef5.

    Once complete, I turned the car off and on again and ran a scan on the ABS/VSA system.

    Test was pass with no codes found.

    20151220_141407_zpszsfjnn2x.

    System Status

    20151220_140354_zps8wgydbfe.

    So far so good, will keep an eye on it and see if any other errors re-appear

    Thanks All.

    Hi,

    I have very similar problem, VSA/ABS light goes on and then off, stay off for a day or 2 and then back on. I don't have a modular reader so don't know what to do, take it to HDS and get rip off for a confirmation of issue or go ahead and get the modules replaced.

    Please advise if there has been any DIY on changing VSA/ABS modules on here. Any other advise will be highly appreciated. I ooccassionaly hear a Grr sound when i start car from static and move for few yards and then it doesn't happen, anything?

    Get the codes read by Honda it's the only way to be sure.

    I thought VSA and ABS lights together was usually more an ABS fault and if you had VSA on its own it's usually the modulator.

    Take it to the dealers and pay for them to plug it in will probably save you money in the long run! You wouldn't want to change the modulator if it's an ABS wheel speed sensor!

    Dave is right - although my scanner does detect the VSA unit and can read codes i would probably go to a Honda dealer to be sure if i get the lights appear again.

    Problem is i hate dealers and prefer Honda specialists garages, these guys are quite local to you Watford/ Kings Langley and are jap/honda specialists.
    They may have the equipment to read Honda sub system fault codes. Defiantly worth a friendly phone call or email inquiry.

    I also assumed that VSA on its own was the modulator itself and both ABS/VSA were the ABS system but could be wrong

    Hi Guys,

    I have an update, but you might find it weird as i did. I wash my car last weekend after 2 months, obviously i am guilty of not giving it a good wash since the summer left. But since the wash car has not shown any illumination light. Not even once....

    Does this indicate something was sitting on the sensor i.e dust, but, or anything...? Which after a wash has gone... Obviously i learnt that, get car washed regularly and treat it with respect by giving a good wash yourself... lol

    Haha, sounds coincidental but give it sometime, let's see how long the light stays off for.

    The sensor are buried quite deep, I doubt you'd be able to get any water to where the sensors are by just washing the car.

    Same thing happened to me about a year ago. Both ABS and VSA lights on and my regular mechanic used Snap-On diagnostics to confirm ABS sensor. Replaced it and all good since.

    PS. Couldn't help but have another look at your Prelude garage entry. Stunning.

    Hopefully it stays off but worth researching into replacement ABS sensors and VSA units so if it does return your prepared.

    Mine is stayed off ever since and have driven over 500 miles already . Fingers crossed.

    Thanks dave, The Prelude has been through some dram over the past month or so but it is back on the road now.

    Morning guys,
    Going to get this checked with Japex today, fingers crossed.... ✌️ Will update you with result of diagonostic scan.

    Cheers

    Ok, have an answer now, Ross from Japex was very helpful, the diagnostics said that "rear RHS sensor has an open circuit".
    The interpretation is that it could be a loose wire connection or an ABS sensor itself. For the connection check it will require full visual check under seats. And if it is ABS sensor than a new sensor from Honda £170 will need to be ordered and put in.

    Any thoughts?

    Does the ABS light illuminate all the time now? or has it since gone out and never came back since?
    £170 is indeed alot of money. although i have heard the copy ones on ebay do work and are only £20 ish.

    If the light has since not returned and it drives fine then i would leave it until there is a permanent issue.
    If the light is on now and doesnt go away then i would consider the £170 and the copy ones.

    Is £170 including the labour? As i have heard the sensors can usually be seized in and have to be drilled out.

    Did they charge you for the diagnosis scan at all?

    How was Japex? Always been meaning to head down there and use them. I heard they are good.
    Are they familiar with the accord I-CTDI?

    Thanks for your reply. Japex are absolute spot on guys, they didn't charge me for diagonostics at all. They know the issues with ICTDI well as the guy prepared me already for a potential pump error and using bma for repair etc.

    ABS and VSA lights are on the dash for a while now, need to get this resolved but I think £170 for part only is too much. They said labour will be of an hour (£60 + Vat) including the removal of rusty screw which usually snaps.
    I will ask them tomorrow if they can use a OEM part from blue print instead of honda.

    My other worry which has pushed me to think more of keeping the cost low is the slipping of clutch which started to happen a week ago. :Frown: that will be costly.

    As said before do you reckon there could only be a open electrical connection which couldn show up as VSA and ABS light...?

    There is a resistance check you can do in the sensor, can't remember what the pucker resistance values are but there are threads on the forum which should have them stated.

    I have a similar issue in my Accord, for the last couple of years the ABS light goes on sometimes in winter. It was diagnosed by Honda as the rear driver side sensor, they wanted ~ £240 p/l. I decided to wait, and so far have been lucky, it never happens during MOT testing.

    Thanks

    Can a OEM part like blue print £70 ish used instead of Honda expensive?
    Any one had an experience? I know the difference will be there but can I not get away with using an after market?

    If it's an OEM part then, by definition, it's from the same supplier that Honda use.

    I doubt that BluePrint supply OEM parts, it'll probably be an aftermarket alternative.

    Personally, I'd buy the cheaper Blueprint alternative.

    I don't know either (and I've just searched through the Honda ESM maintenance manual to no avail). But, using a multimeter, it should be relatively simple to find the suspect sensor connector, unplug it and read the resistance... Then find another wheel sensor, measure that one, then compare the readings. I suggest that if they're within 10% then the suspect sensor is OK and the problem is a vehicle wiring issue which will need further investigation using the multimeter and checking connectors.
