ABS & VSA Warning Lights stay on

[Blue2Basingstoke]

Any ideas 

When I start my Honda Accord 2.4 [05 plate] the following warning lights permanently stay on ; (1) ABS, (2) VSA Activation & (3) VSA System

[Trevor]

Sounds like an ABS sensor has gone faulty

Thank You, I’m going to have a look at the weekend. Then I’ll let you know

[Blue2Basingstoke]

It was the N/S/R sensor which was luckily easy to replace and solved this issue and then I just needed a diagnostics machine to reset the VSA. Thanks for the advice

[Trevor]

glad you resolve it and hopefully wasn't too expensive

A local garage provided the assistance of their diagnostics machine to reset the VSA (obviously for a small fee)

Hi, anyone experienced an ABS motor relay :open circuit fault  , ABS and VSA light stay on and sometimes goes off , ABS /VSA light goes on after some kms running and after starting engine again, checked the ABS relay ,the motor -everything is fine , the only thing have to check is inside  the motor relay of the  ABS module. has any one had experienced the same issue...Thanks.

madfogs . Can't say I have come across this one before but I would replace the relay if in doubt.
If it is an Omron relay then I have had these go on me before (air conditioning main relay).

More than likely a faulty wheel speed sensor causing this issue

Ok and how can i check them and are they just on the front wheels or on all 4 wheels

[Trevor]

they are on all four wheels and the best method is to disconnect the connector (usually inside the boot area and under the bonnet) and measure the resistance from the sensor.

They should all be approximately the same (give or take a few ohms).

If one reading is non existent then more than likely an open circuit meaning it is defective.

Ok thanks that s answer i can do something but one thing opencircuit defective but why obd screams abspump motorrelay open circuit.

And the stupid thing is it s not continously some drive no problem then sometime while driveng this morning turning on ignition key.

 

And only i can get fault out while driving ans turn ignition key off for 15sec then while rolling start and then gone.

Some tomes 3 times restart.

 

Firts i going to check the wheel sensors.

Thank u again for answer
