Can Communication System -- Precaution



1.DISCONNECT CABLE FROM NEGATIVE BATTERY TERMINAL
CAUTION:
Wait at least 90 seconds after disconnecting the cable from the negative (-) battery terminal to disable after the SRS system.

  1. Be careful when replacing parts. Incorrect replacement could affect the performance of the steering system and result in hazardous driving.


2.STEERING SYSTEM HANDLING PRECAUTIONS

  1. Be careful 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 a Supplemental Restraint System (SRS) 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 precaution for the SRS (COROLLA_ZRE142 RM000000KT10H0X.html).


4.BUS WIRE REPAIR


    Corolla. Zre142 Aze141

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

    NOTICE:
    1. The CANL bus wire and CANH bus wire must be installed together at all times.
    2. When installing, make sure that the wires are twisted.
    3. CAN bus wires are likely to be influenced by electrical noise if they are not twisted.
    4. The difference in length between the CANL bus wire and CANH bus wire should be 100 mm (3.937 in.) or less.
    5. Leave approximately 80 mm (3.150 in.) loose in the twisted wires around the connector.

  2. Do not use bypass wiring between the connectors.

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

5.CONNECTOR HANDLING

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

  2. 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.
