So about 6 months back this issue happened where my abs, brake, traction control light as well as a warning message about check vsc popped up while I was driving. Got kind of worried so I restarted my car and everything was gone... Until last week. Noticed that this keeps happening while I'm in heavy traffic and on the brakes on and off. Any Ideas on what this could be? I drive an 06 IS350 with 108k miles

 

Get a scanner and check to see if there are any codes that were stored.

 

You won't find any code for those problem.
Check VSS connector make sure it's all good

 

scanner didnt pull anything. i'll check the connector

 

You aren't going to figure this out yourself .... trip to the dealer is in your future.

 

The point of asking here is to avoid the dealership

 

This could be a lot of things and it's probably only going to show the code when the lights are actually on. Wheel speed sensors, steering angle sensor, brake lamp switch, faulty abs motor or module. Not saying that you should take it to a dealer, but this will be difficult to diagnose being intermittent. If you know how to get it to act up, you need to have someone watching a scanner while driving. Also, your generic code reader won't read codes in the abs module, they just read the PCM. Hope your able to figure it out, nothing worse than having your dash lit up like a Christmas tree.
