INSPECTION PROCEDURE

Note


  • Turn the engine switch off before measuring the resistances of the CAN main wire and the CAN branch wire.

  • After the engine switch is turned off, check that the key reminder warning system and light reminder warning system are not in operation.

  • Before measuring the resistance, leave the vehicle as is for at least 1 minute and do not operate the engine switch, any other switches or doors. If any doors need to be opened in order to check the connectors, open the doors and leave them open.

Tech Tips


  • 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 will help determine the cause of the malfunction.

    3. When there is a short in one or more of the branch wires:


      1. Reconnect all of the connectors to the CAN junction connector, except for the one that was disconnected last (the short-circuited bus wire). Check that the resistance shown on the tester becomes normal (between 54 and 69 Ω) to confirm that there is a short in only one branch wire.

        Tech Tips


        • The shape of connectors connected to the CAN junction connector which has an earth terminal is the same. The connectors connected to the CAN junction connector can be distinguished by the colors of the bus wire and the connecting side of the junction connector.

        • Reconnecting the connectors to non-specified positions on the CAN junction connector does not affect system operation. However, it is preferred to reconnect the connectors to their specified positions to avoid negative effects on the wiring such as tension on the wiring harnesses, and to make future maintenance easier.

Check that the resistance shown on the tester becomes normal (6 kΩ or higher (for +B short) or 200 Ω or higher (for ground short)) to confirm that there is a short to +B or GND in only one branch wire.

        Tech Tips


        • The shape of connectors connected to the CAN junction connector which has an earth terminal is the same. The connectors connected to the CAN junction connector can be distinguished by the colors of the bus wire and the connecting side of the junction connector.

        • Reconnecting the connectors to non-specified positions on the CAN junction connector does not affect system operation. However, it is preferred to reconnect the connectors to their specified positions to avoid negative effects on the wiring such as tension on the wiring harnesses, and to make future maintenance easier.

      Tester Connection Condition Specified Condition
      G20-27 (CANH) - G8-16 (BAT) Cable disconnected from negative (-) battery terminal 6 kΩ or higher

      G20-28 (CANL) - G8-4 (CG) Engine switch off 200 Ω or higher

      Tech Tips

      If the resistance changes to 6 kΩ or higher (for +B short) or 200 Ω or higher (for ground short) when the connector is disconnected from the ECU, there may be a short to +B or GND in the ECU.
