Toyota RAV4 (XA40) 2013-2018 Service Manual: 4Wd control ecu communication stop mode
Description
Hint:
For vehicle with 4wd only.
Wiring diagram
Inspection procedure
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.
- Check can bus line for disconnection (4wd control ecu branch wire)
- Disconnect the e57 4wd control ecu connector.
- Measure the resistance of the wire harness side connector.
Standard resistance
- Check wire harness (4wd control ecu - battery and body ground)
- Disconnect the e57 4wd control ecu connector.
- Measure the resistance of the wire harness side connector.
Standard resistance 
- Measure the voltage of the wire harness side connector.
