Starter Cut Relay; Engine Switch; Starter Relay; Main Body Ecu - Toyota RAV4 2009 Features Manual

Starter Control (Models with Smart Key System)
1) General
D Once the engine switch is pressed, this function operates the starter until the engine starts, provided
that the brake pedal is depressed and the shift lever is in the P or N position. This prevents application
of the starter for an inadequate length of time and it also prevents the engine from being cranked after
it has started.
D When the ECM detects a start signal (STSW) from the main body ECU, it monitors engine speed (NE)
and operates the starter until it determines that the engine has started. If the engine has already started,
the ECM will not operate the starter, even if the ECM receives the start signal (STSW).
