Title: NETWORKING: CAN COMMUNICATION SYSTEM: TERMINALS OF ECU; 2021 - 2022 MY Camry [10/2020 - 08/2022]

TERMINALS OF ECU

NOTICE:

  • 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.

    Click here 2020 - 2024 MY Camry [03/2020 -        ]; INTRODUCTION: REPAIR INSTRUCTION: PRECAUTION

  • 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 1 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 here 2021 MY Camry [10/2020 - 08/2021]; NETWORKING: CAN COMMUNICATION SYSTEM: DIAGNOSIS SYSTEM 2022 - 2024 MY Camry [08/2021 -        ]; NETWORKING: CAN COMMUNICATION SYSTEM: 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.
