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 ...
Circuit description
In the diagram below, when the engine is cranked, current flows from terminal
st2 of the ignition switch to
the starter relay coil and also current flows to terminal sta of the ecm (sta
signal).
When the sta signal and ne signal are input to the ecm, tr is turned on, current
flows to the c ...
