Normal
Damaged or disconnected
wiring or short-circuit of G
sensor input circuit, or G
sensor malfunction.
With the ignition key at the
ON position and the vehicle
speed at 40 km/h (25 mph)
or higher, the output
voltage of the generator 'I"
terminal is approximately
The low-pressure switch is
not switched OFF even
though the attitude-control
function is performed 30
times. The return pump is
13
activated frequently.
Damaged or disconnected
wiring of the steering
angular-velocity sensor
input circuit, or a
malfunction of the steenng
angular-velocity sensor.
Vehicle condition
Alarm light illuminates;
among attitude-control
modes, only rolling control
stops.
(Others operate normally.)
The charging warning light
illuminates, and,
furthermore, the system
does not function when the
vehicle is stopped (vehicle
speed of 3 km/h (2 mph) or
lower).
NOTE
The alarm light does not
illuminate, and,
furthermore, there is no
detection of harness
damage or disconnection
between the generator "L"
terminal and the ECU.
The alarm light illuminates,
and only the attitude-control
function stops. (Other
functions are normal.)
The alarm light illuminates,
and the attitude-control
function stops. The
damping force is held to
MEDIUM, and the vehicle
height is held to NORMAL
