Vsc..stability Control

[mikel]

AFTER 45K MILES MY DASH LIT UP AND SIRENS RANG SHOWING WARNINGS ON TRACTION BRAKES ETC. I TOOK IT TO LEXUS DEALER WHO WOULD LOOK AT IT (LEXUS CHESTER WOULDN'T) AND WAS ADVISED IT WAS THE VSC UNIT WHICH WAS FAULTY. I WAS ADVISED IT WAS PROBABLY A CHIP BUT IT COULD NOT BE REPAIRED. A NEW VSU WAS ABOUT £1700. FORTUNATELEY I FOUND A REPLACEMENT A LOT LESS. IS THIS A COMMON PROBLEM?(1) DOES ANYBODY KNOW IF THE OLD ! UNIT CAN BE SORTED.(2)

YIKES!!!

Never had a problem with mine ( Mk2 ) except it kicks in all too often ;)

Not heard of this problem before.

As for repairing it. It depends if the thing can be taken apart for a start. Should be able to do component testing against common devices (transistors, logic ICs etc) but if there is a problem with a custom chip or a programmable device then you wouldn't be able to get the replacement part. Worth a go though as it's an expensive device.

There is a VSC OFF switch available from :

The fault is with the brake master cylinder, not the VSC ECU electronics, and that also controls the ABS.

Just turning off the VSC would not help.
