3. HANDLING PRECAUTIONS FOR SRS AIRBAG SYSTEM
(a) The vehicle is equipped with a Supplemental Restraint System (SRS). Failure to carry out service operations in the correct sequence could cause the SRS to unexpectedly deploy during servicing. This may cause a serious accident.
Before servicing (including inspection, replacement, removal and installation
of parts), be sure to read the precautionary notices for the Supplemental Restraint
System (See page .gif)
).
4. PRECAUTIONS FOR REMOVAL, INSTALLATION AND REPLACEMENT OF ELECTRONIC MOTOR POWER STEERING COMPONENTS
(a) After replacing the power steering ECU assembly, clear the rotation angle
sensor calibration value, initialize the rotation angle sensor, and calibrate the
torque sensor zero point (See page ).
5. HANDLING PRECAUTION
(a) When handling the electronic parts:
- Avoid any impact to electronic parts such as ECUs and relays. Replace them with new ones if dropped or subjected to a severe blow.
- Do not expose any electronic parts to high temperatures or humidity.
- In order to prevent deformation or malfunctions due to static electricity, do not touch the connector terminals.
(b) Before disconnecting the connectors related to the electronic power steering system, turn the ignition switch to ON, center the steering wheel and then turn the ignition switch off.
6. PRECAUTIONS FOR CAN COMMUNICATION
(a) CAN communication lines are used to receive information from the skid control ECU and the ECM, and to transmit warnings to the combination meter.
When there are any problems in the CAN communication lines, DTCs of the CAN communication line are output.
(b) Perform troubleshooting for the communication line problems when DTCs of the CAN communication are output. Be sure to start troubleshooting on the power steering system after confirming that the CAN communication system is normal.
(c) Since the CAN communication line has its own length and route, it cannot be repaired temporarily with a bypass wire, etc.
