Toyota RAV4 (XA40) 2013-2018 Service Manual: Main body ecu communication stop mode
Description
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 (main body ecu branch wire)
- Disconnect the e17 main body ecu connector.
- Measure the resistance of the wire harness side connector.
Standard resistance 
- Check wire harness (main body ecu - battery and body ground)
- Disconnect the 1e and 1b junction block connectors.
- Measure the resistance of the wire harness side connector.
Standard resistance
- Measure the voltage of the wire harness side connector.
