WIRING DIAGRAM
CAUTION / NOTICE / HINT
- NOTICE:
- ·
Depending on the parts that are replaced during vehicle inspection or maintenance, performing initialization, registration or calibration may be needed.
·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 (-) auxiliary 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 (-) auxiliary battery terminal. Therefore make sure to read the disconnecting the cable from the negative (-) auxiliary battery terminal notices before proceeding with work.
·When disconnecting the cable from the negative (-) auxiliary battery terminal.
- HINT:
-
When the cable is disconnected / reconnected to the auxiliary battery terminal, systems temporarily stop operating. However, each system has a function that completes learning the first time the system is used.
·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.
·When replacing the combination meter assembly, make sure to update the ECU security key.
- 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.
PROCEDURE
Pre-procedure1
Disconnect the I275 radio and display receiver assembly connector.
Disconnect the I5 combination meter assembly connector.
Procedure1
