The ABS light is always on - 1996 Honda Odyssey

You have a Malfunction Light on

ABS Light --- that is not something new
to anyone,check for codes as always

Most likely need professional scan tool
to access the abs module, so you also need
a repair shop as always

Check the battery for the no start

The ABS sensors are in airbags depending on the model you have. Best way is to use a ODBII reader to check the airbags to find the fault.

Some alfa's have issues with the connectors coming loose, it is common in the 147 and 156 for people to end up soldering the connector under the passenger seat.

Yes the sensor is replaceable if that is the problem, but it can be a wiring problem as well.

check the brake fluid level in the reservoir. if full, try poking the float back to the surface. sometimes it sticks sunk. the abs light will always illuminate when the red brake light is on if your vehicle is equip t with abs. it means the abs system is inactive.

needs to have system checked,could be as simple as debris,grease,dirt fouling an abs sensor.best bet is to take it to a dealer,another thing to consider is if you have a warning light on for something like abs or airbag etc,that system is out of order and will not work till fault is rectified.

You have a faulty sensor.You will have to get a diagnostic check to findthe faulty one.

The ABS system always is engaged when the brakes are applied. If you are talking about the ABS light coming on then it is a little bit of a different story. If the light has come on at all there will always be a code stored. I would take it to a shop that has a scan tool to read ABS lights and ask them what the computer is saying. This is the only true way to get this problem fixed.

Have you checked your brake fluid? It may be low or an indication that the brake pads are worn, causing the light to stay on.

I would suspect a speed sensor.

I have the feeling that the cv was replaced with one that didn't have a tone ring (part of the ABS) on it, or the tech neglected to put the sensor back in the knuckle.
Definitely take it back. Good luck!
