CAUTION:
·

When performing the confirmation driving pattern, obey all speed limits and traffic laws.

·
A340358

Before the following operations are conducted, take precautions to prevent electric shock by turning the power switch off, wearing insulated gloves, and removing the service plug grip from HV battery.

-

Inspecting the high-voltage system

-

Disconnecting the low voltage connector of the inverter with converter assembly

-

Disconnecting the low voltage connector of the HV battery


·
A371653

To prevent electric shock, make sure to remove the service plug grip to cut off the high voltage circuit before servicing the vehicle.

·
A358042

After removing the service plug grip from the HV battery, put it in your pocket to prevent other technicians from accidentally reconnecting it while you are working on the high-voltage system.

*a Without waiting for 10 minutes


After removing the service plug grip, wait for at least 10 minutes before touching any of the high-voltage connectors or terminals. After waiting for 10 minutes, check the voltage at the terminals in the inspection point in the inverter with converter assembly. The voltage should be 0 V before beginning work.

HINT:

Waiting for at least 10 minutes is required to discharge the high-voltage capacitor inside the inverter with converter assembly.




NOTICE:
·

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.

·

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 10 minute or more before measuring the resistance.

·

This section describes the standard values for all CAN related components.



HINT:
·

The systems (ECUs and sensors) that use CAN communication vary depending on the vehicle and optional equipment. Check which systems (ECUs and sensors) are installed to the vehicle.

Click herePower Source / Network>NETWORKING>CAN COMMUNICATION SYSTEM (for HEV Model)>DIAGNOSIS SYSTEM

·

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.
