Toyota Venza: Transmission Control Switch Circuit
DESCRIPTION
When the shift lever is in S and it is moved toward "-" or "+", it is possible to select different shift ranges (1st through 6th ranges).
Moving the shift lever toward "+" increases the shift range by one, and moving the shift lever toward "-" decreases the shift range by one.

DESCRIPTION
The battery supplies electricity to the TCM even when the ignition switch is
off. This power allows the TCM to store data such as DTC history and freeze frame
data. If the battery vol ...
ECU Power Source Circuit
DESCRIPTION
When the ignition switch is turned to ON, voltage from the ECM's MREL terminal
is applied to the EFI MAIN relay. This causes the contacts of the EFI MAIN relay
to close, which sup ...

DESCRIPTION
When the A/C amplifier is turned on, a magnetic clutch ON signal is sent from
the MGC terminal of the A/C amplifier. Then, the MGC relay turns on to operate the
magnetic clutch.
