POWER SUPPLY CONTROL

.

ACC POWER CUT-OFF FUNCTION (THE
INITIAL CONDITION: WITHOUT FUNC-
TION)

The function has been added that the ACC power
supply is cut-off when 30 or 60 minutes has elapsed
with the ignition switch in the ACC position. This can
improve the function to avoid battery drain together
with the headlight automatic shutdown function and
interior light automatic shutdown function.

ACC power cut-off function and its time to ACC
power cut-off can be set. (Refer to Customization
Function

P.54A-40

).

.

ENGINE CONTROL <VEHICLES WITH
TC-SST>

After the ignition switch is turned to the LOCK (OFF)
position and the engine stops running, it takes
approximately 1 second until the power of the vehicle
is turned off. During the period until engine is
stopped, the gear engagement in TC-SST is
released in order to start the engine smoothly at the
next startup.

FAN CONTROL

Even after the engine is stopped, if the temperature
in engine compartment is high, the engine compart-
ment temperature is lowered by the operation of
cooling fan for a specified period.
