Toyota RAV4 Service Manual: Terminals of ecu (2005/11-2006/01)
Notice:
- Turn the ignition switch off before measuring the resistances of the main wire and the branch wire.
- After the ignition switch is turned off, check that the key reminder warning system and light reminder warning system are not in operation.
- Before measuring the resistance, leave the vehicle for at least 1 minute and do not operate the ignition switch, any switches or doors. If doors need to be opened in order to check connectors, open the doors and leave them open.
Hint:
Operating the ignition switch, any switches or any doors triggers related ecu and sensor communication with the can, which causes resistance variation.

When towing active torque control 4wd vehicles
Use one of the methods shown below to tow the
vehicle.
If the vehicle has trouble in the chassis and drivetrain,
use method 1 (flat bed truck).
Notice:
Do not use any towing method other than those
shown above.
For example, the towing methods shown below are
dangerous or dama ...
The rear cross traffic alert function detection areas
The areas that vehicles can be detected in are outlined below.
To give the driver a more consistent time to react, the buzzer can alert
for faster vehicles from farther away.
Example:
The rear cross traffic alert function is operational when
The bsm main switch is set to on.
