Can Communication System (For Hatchback Except Separate Type Yaw Rate Sensor) -- Precaution


NOTICE:
After turning the ignition switch off, waiting time may be required before disconnecting the cable from the battery terminal. Therefore, make sure to read the disconnecting the cable from the battery terminal notice before proceeding with work (YARIS_NCP93 RM00000482L007X.html).

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 hazards when 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 installation/removal, inspection and replacement of parts), be sure to read the precautionary notice for the Supplemental Restraint System.

3.BUS LINE REPAIR


    Yaris. Ncp93, 131

  1. After repairing the bus line with solder, wrap the repaired part with vinyl tape (YARIS_NCP93 RM000000UZ309WX.html).

    NOTICE:
    1. The CANL bus line and CANH bus line must be installed together.
    2. When installing the CAN bus lines, be sure to twist them.
    3. CAN bus lines are likely to be influenced by noise if the bus lines are not twisted together.
    4. Leave approximately 80 mm (3.15 in.) loose in the twisted wires around the connectors.
    5. When repairing the CAN bus lines, do not change the length of the lines. (Make sure that the length of the CANH bus line and CANL bus line are the same.)
