Toyota RAV4 (XA40) 2013-2018 Service Manual: Check 4wd control ecu (for 4wd)
Notice:
- Turn the ignition switch off before measuring the
resistances of the main wire and 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 as
is for at least 1 minute and do not operate the ignition
switch, any other switches or the 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 other switches or the doors
triggers related ecu and sensor communication with the
can, which causes resistance variation.
