CAN COMMUNICATION SYSTEM PRECAUTION


  1. 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.

  2. SRS AIRBAG SYSTEM HANDLING PRECAUTIONS


    1. This vehicle is equipped with an SRS (Supplemental Restraint System) which includes components 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 Supplemental Restraint System Click here.

  3. BUS LINE REPAIR


    1. A0161LM

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

      Note


      • The CANL bus line and CANH bus line must be installed together all the times.

      • When installing, make sure to twist them.

      • CAN bus lines are likely to be influenced by electrical noise if they are not twisted.

      • The difference in length between the CANL bus line and CANH bus line should be 100 mm (3.94 in.) or less.

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

    2. A0161H6E15

      Do not use a bypass wire between the connectors.

      Note

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

  4. CONNECTOR HANDLING


    1. A0161K6E01

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

    2. A015ZHCE15

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