  2. STEERING SYSTEM HANDLING PRECAUTIONS


    1. Care must be taken when replacing parts. Incorrect replacement could affect the performance of the steering system and result in hazardous driving.

  3. SRS AIRBAG SYSTEM HANDLING PRECAUTIONS


    1. This vehicle is equipped with an SRS (Supplemental Restraint System) which includes parts such as the driver airbag and front passenger airbag. Failure to carry out service operations in the correct sequence could cause unexpected SRS deployment during servicing and may lead to a serious accident. Before servicing (including removal or installation of parts, inspection or replacement), be sure to read the precautionary notice for the SRS Click here.

  4. BUS WIRE REPAIR


    1. A017B86

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

      Note


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

      • When installing, make sure that they are twisted.

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

      • The difference in length between the CANL bus wire and CANH bus wire should be 100 mm (3.937 in.) or less.

      • Leave approximately 80 mm (3.150 in.) loose in the twisted wires around the connector.

    2. A017CUIE14

      Do not use bypass wiring between the connectors.

      Note

      The ability of the twisted bus wires to resist interference will be lost if bypass wiring is used.

  5. CONNECTOR HANDLING


    1. A017C8EE01

      When checking resistance with a tester, insert the tester probes from the backside (harness side) of the connector.

    2. A017CQYE13

      Use service wires to check the connector if it is impossible to check continuity from the rear of the connector.

  6. 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.
