lights

the brake lights on my 639 vito stay on when ignition is turned on, if you disconnect the brake switch and then reconnect it with the engine running everything works ok, once you turn the ignition off and on again all three lights stay on any ideas

I would start by replacing the brake light switch. It may still be the culprit. 

 

If that doesn't solve the problem then I would look at the wheel speed sensor. 

 

Ideally you want to scan the codes from the ABS module because what we are doing is just guessing.
