CAUTION / NOTICE / HINT
CAUTION:
When performing the confirmation driving pattern, obey all speed limits and traffic laws.
NOTICE:
- 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.

- 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 or any switches, or opening or closing the doors. After that, disconnect the cable from the negative (-) auxiliary battery terminal and leave the vehicle for 1 minute or more before measuring the resistance.
- After the ignition switch is turned off, there may be a waiting time before
disconnecting the negative (-) auxiliary battery terminal.

- When disconnecting and reconnecting the auxiliary battery.
HINT:
When disconnecting and reconnecting the auxiliary battery, there is an automatic learning function that completes learning when the respective system is used.
Click here
- Some parts must be initialized and set when replacing or removing and installing
parts.
Click here
- 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 for 1 minute or more. Then operate the suspected malfunctioning system and drive the vehicle at 60 km/h (37 mph) or more for 5 minutes 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 as normal.

HINT:
- Before disconnecting related connectors for inspection, push in on each connector body to check that the connector is not loose or disconnected.
- When a connector is disconnected, check that the terminals and connector body are not cracked, deformed or corroded.
