"Vehicle Stability Control System Failure Warning - Lexus 2006 lx 470 Manual

The vehicle stability control system is activated when the
vehicle speed is about more than 15 km/h (9 mph).
You may hear a sound in the engine compartment for a few
seconds when the engine is started or just after the vehicle
begins to move. This means that the vehicle stability control
is in the self check mode and does not indicate a malfunction.

the vehicle stability control system off. At this time, the "VSC
OFF" indicator comes on with the center differential lock
indicator light. (For details, see "Four wheel drive system" on

"Vehicle stability control system failure warning

These lights warn when there is a problem somewhere in the
vehicle stability control system or active traction control
system.
If the "VSC/TRAC" warning light and "VSC OFF" indicator light
come on, have your vehicle checked by your Lexus dealer as
soon as possible. However, there is no problem even if the
"VSC/TRAC" warning light comes on when the brake actuator
temperature becomes high. (For details, see "Active traction
control system" on page 288.)
When the "ABS" warning light comes on, the vehicle stability
control system is not operating.
The lights will come on when the ignition key is turned to "ON",
and will go off after a few seconds.
The lights may stay on for 60 seconds after the ignition key is
turned to the "ON" position. It is normal if they go off after a few
seconds.
