Circuit description
The actuator motor is operated by signals from the cruise control ecu assy.
Acceleration and deceleration
signals are transmitted by changes in the duty ratio (see below).
Duty ratio:
the duty ratio is the ratio of the period of continuity in one cycle. For
example, if a is the period of co ...
Check short circuit
If the wire harness is ground shorted as shown in fig. 5,
Locate the section by conducting a resistance check with
the body ground in step (b).
Check the resistance with the body ground.
Disconnect connectors a and c and measure the
resistance between terminals 1 and 2 ...
PCS (Pre-Collision System)
The pre-collision system
uses sensors to detect
objects in the path
of the vehicle. When the
system determines that the
possibility of a frontal collision
with a detectable
object is high, a warning
operates to urge the driver
to take evasive action and
the potential brake pressure
is increased to h ...
