CAUTION / NOTICE / HINT
NOTICE:
-
Depending on the parts that are replaced during vehicle inspection or maintenance, performing initialization, registration or calibration may be needed.

-
Inspect the fuses for circuits related to this system before performing the following procedure.
-
When replacing the combination meter assembly, make sure to replace it with a new one. If a combination meter assembly which was installed to another vehicle is used, the information stored in the combination meter assembly will not match the information from the vehicle and a DTC may be stored.
-
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.

HINT:
-
Before disconnecting related connectors for inspection, push in on the connector body to check that each connector is not loose or disconnected.
-
When a connector is disconnected, check that the terminals and connector body are not cracked, deformed or corroded.
-
When the cable is disconnected / reconnected to the battery terminal, systems temporarily stop operating. However, each system has a function that completes learning the first time the system is used.
