ACTIVE-ELECTRONIC CONTROL SUSPENSION - Troubleshooting
Diagnostic
Malfunction
trouble
code No.
An abnormal signal (a signal
unlike any normal srgnal
such as an error code, etc.)
is input from the front
height sensor; or, a
malfunction of the
"22
vehicle-height
discrimination circuit within
the ECU.
An abnormal signal is input
from the rear height sensor;
or, a malfunction of the
discrimination circuit within
the ECU.
"23
There is damaged or
disconnected wiring, or a
short-circuit, of the
vehicle-speed sensor Input
circuit.
(The throttle is open 30% or
"24
more, and the output of the
generator "L" terminal is
HIGH level, but even so the
input of the vehicle-speed
pulses is not 30*' seconds
or longer.)
There is damaged or
disconnected wiring of
sensor input circuit.
(The rear internal
pressure is abnormally
25
high.)
