Toyota RAV4 (XA40) 2013-2018 Service Manual: Can bus line
Description
When any dtc for the can communication system is output, first measure the resistance between the terminals of the dlc3 to specify the trouble area, and check that there is not a short in the can main wire, between the main wire, to +b, or to gnd.
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 wire (main wire for open, can bus lines for short circuit)
- Measure the resistance of the dlc3.
Standard resistance
