Terminals Of Ecu [08/2015 - 08/2016]
WARNING: This page is about a different car, the 2018 Toyota Corolla, 2017 Toyota Corolla, 2016 Toyota Corolla, 2015 Toyota Corolla, and 2014 Toyota Corolla. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
- 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.
Refer to PRECAUTION [08/2015 - 08/2016]
- Turn the ignition switch off before measuring the resistances between CAN main bus lines and between CAN branch lines.
- Turn the ignition switch off before inspecting CAN bus lines for a ground short.
- 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 section describes the standard values for all CAN related components.
HINT:
- 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.
