Terminals Of Ecu [09/2014 - 08/2016]
NOTE:
- After turning the engine 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.
Refer to PRECAUTION [09/2014 - 11/2017]
- Turn the engine switch off before measuring the resistances between CAN main bus lines and between CAN branch lines.
- Turn the engine switch off before inspecting CAN bus lines for a short to ground.
- Before measuring the resistance of the CAN bus, turn the engine 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 1 minute or more before measuring the resistance.
- This service information describes the standard values for all CAN related components.
HINT:
- Operating the engine 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.
- NO. 1 CAN JUNCTION CONNECTOR
- Check the No. 1 CAN junction connector.
