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 (-) battery terminal and leave the vehicle for 10 minutes or more before measuring the resistance.

·

After the ignition switch is turned off, there may be a waiting time before disconnecting the negative (-) battery terminal.

HINT:

When disconnecting and reconnecting the battery, there is an automatic learning function that completes learning when the respective system is used.

Some parts must be initialized and set when replacing or removing and installing parts.

Click hereGeneral>SETUP>WHEN REPLACING OR REMOVING/INSTALLING PARTS>WORK PROCEDURE

·

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.



PROCEDURE

1.CHECK FOR OPEN IN CAN BUS WIRE
NOTICE:

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 (-) battery terminal and leave the vehicle for 10 minutes or more before measuring the resistance.


HINT:

Operating the ignition switch, any other switches or door triggers related ECU and sensor communication on the CAN. This communication will cause the resistance value to change.


a.

Disconnect the cable from the negative (-) battery terminal.
