Do Not Sell My Personal Information Jump to content

Hi guys,

From time to time got VSC warning light on a dashboard. It could some sensors or wires because it happens mostly when its raining or high humidity or low temperatures outside.

Please tell me guys where to start to find what is causing this problem.

Thx Alex.

I had the same issue on my LS400. Would happen all the time in the winter, rarely in the summer. Garage reckoned it was a faulty speed sensor letting in damp. It works always reset after a short drive, and a switch off/on routine, so I never got it properly sorted,

First step would be to get any stored codes read from the VSV data link port, this should then guide you to what the problem may be.

There are so many inputs into the VSC/TRAC/ABS ECU that it would be very time consuming and expensive to start guessing at the cause although wheel ABS sensors are always suspect due to them being subjected to extreme conditions due to their locations but if one was faulty I would expect the ABS warning light to be on also.
