32 Out of vehicle speed of
cruise control operation
•Controlled vehicle speed decreased under
the limit during cruising.
•Set operation was performed at vehicle
speed unavailable for setting.
•Resume operation was performed with-
out memorized vehicle speed.
This DTC is displayed, though the vehicle
speed is increased to the speed available for
cruise set and set operation was performed
again. AND 32 VEHICLE SPEED SENSOR, Diag-
nostic Procedure with Diagnostic Trouble

33 WAIT is prohibited after
operating accelerator
pedal.
Controlled vehicle speed increased above
the limit during cruising.
This DTC is displayed when driving at higher
speed than appropriate cruise control
speed. In this case, lower the vehicle speed
to the speed available for cruise set, and
perform cruise set operation again.
34 Prohibited when accelera-
tor pedal position large is
continued.
The vehicle has been driven at higher speed
than set vehicle speed for an abnormally
long time (approximately 10 minutes) during
cruise driving.
This DTC is displayed when driving for a
long period of time at higher speed than
appropriate cruise set vehicle speed by
operating accelerator pedal. In this case,
release the cruise set.
35 Prohibited when vehicle
speed feedback unavail-
able.
Set vehicle speed cannot be kept because
of some reasons (steep uphill, parking
brake, abnormal decrease of engine output,
etc.) during cruise driving.
This DTC is displayed when driving condi-
tion is not suitable for cruise control. Perform
cruise set operation again after clearing the
possible cause.
41 VDC/TCS operation Vehicle dynamics control (VDC) or TCS is
operated during cruise driving or cruise set-
ting.
This DTC is displayed when driving condi-
tion is not suitable for cruise control. Perform
cruise set operation again after clearing the
possible cause.
