Terminals Of Ecu [11/2023 - ]

NOTE:

After the ignition switch is turned off, there may be a waiting time before disconnecting the negative (-) battery terminal.
Refer to BEFORE DISCONNECTING BATTERY [11/2023 - ]
When disconnecting and reconnecting the battery.
HINT:

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

Refer to AUTOMATIC LEARNING CHART [11/2023 - ]
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.
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.
Refer to SYSTEM DIAGRAM [11/2023 - ]
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.
