Caution / Notice / Hint
NOTE:
- Before measuring the resistance of the CAN bus, turn the ignition switch off and leave the vehicle for 1 minute or more without operating the key, switches or opening or closing the doors. After that, disconnect the cable from the negative (-) battery terminal and leave the vehicle for 1 minute or more before measuring the resistance.
- After turning the ignition switch off, waiting time may be required before disconnecting the cable from the negative (-) battery terminal. Therefore, make sure to read the disconnecting the cable from the negative (-) battery terminal notices before proceeding with work.

- Because the order of diagnosis is important to allow correct diagnosis, make sure to begin troubleshooting using How to Proceed with Troubleshooting when CAN communication system related DTCs are output.
- After performing repairs, perform the DTC check procedure and confirm that the DTCs are not output again.
- DTC check procedure: Turn the ignition switch to ON and wait at least 61 seconds, and then drive the vehicle at a speed of 20 km/h (12 mph) or more for 300 seconds or more.
- After the repair, perform the CAN bus check and check that all the ECUs and sensors connected to the CAN communication system are displayed.
Refer to DIAGNOSIS SYSTEM [08/2013 - 04/2014] Refer to DIAGNOSIS SYSTEM [04/2014 - 08/2015] Refer to DIAGNOSIS SYSTEM [08/2015 - 08/2016]
HINT:
- Operating the ignition switch, any other switches or a door triggers related ECU and sensor communication on the CAN. This communication will cause the resistance value to change.
- Even after DTCs are cleared, if a DTC is stored again after driving the vehicle for a while, the malfunction may be occurring due to vibration of the vehicle. In such a case, wiggling the ECUs or wire harness while performing the inspection below may help determine the cause of the malfunction.
