  5. BUS WIRE REPAIR


    1. A01SHPH

      After repairing the bus wire with solder, wrap the repaired part with vinyl tape.

      Note


      • The CANH bus wire and CANL bus wire must be installed together.

      • When installing the CAN bus wires, make sure to twist them.

      • CAN bus wires are likely to be influenced by noise if the bus wires are not twisted together.

      • Leave approximately 80 mm (3.15 in.) loose in the twisted wires around the connectors.

    2. A01SI9SC02
      *1 By-pass Wire

      Do not use by-pass wiring between the connectors.

      Note

      The protective effect of the twisted wire harness will be lost if bypass wiring is used.

  6. CONNECTOR HANDLING


    1. A01SHETC02
      *1 Tester Probe

      When inserting probes into a connector, insert them from the rear of the connector.

    2. A01SK1PC02
      *1 Repair Wire

      Use a repair wire to check the connector if it is impossible to check resistance from the rear of the connector.

  7. PRECAUTIONS FOR INSPECTING OR REPLACING CAN JUNCTION CONNECTOR


    1. If the CAN junction connector is removed from the vehicle for inspection or replacement, make sure to install the CAN junction connector and all wire harnesses to their original locations with tape and the clamps.
