Toyota RAV4 (XA40) 2013-2018 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.
- Junction connector
- No. 1 Junction connector
-
No. 2 Junction connector
- No. 3 Junction connector

fuses
If any of the electrical components do not operate, a fuse may
have blown. If this happens, check and replace the fuses as necessary.
Vehicles without a smart key system:
turn the engine switch to the “lock” position.
