PRECAUTION FOR STEERING SYSTEM HANDLING
Be careful when replacing parts. Incorrect replacement could affect the performance of the steering system and result in hazardous driving.
PRECAUTION FOR SRS AIRBAG SYSTEM HANDLING
This vehicle is equipped with a Supplemental Restraint System (SRS) which includes parts such as airbags for the driver and front passenger. Failure to carry out service operations in the correct sequence could cause unexpected SRS deployment during servicing and may cause a serious accident. Before servicing (including removal or installation of parts, inspection or replacement), be sure to read Precaution for SRS.

BUS LINE REPAIR
After repairing a bus line with solder, wrap the repaired part with electrical tape.
- NOTICE:
- ·
The CANL bus line and CANH bus line must be installed together at all times.
·When installing, make sure that these lines are twisted, because CAN bus lines are likely to be influenced by electrical noise if the bus lines are not twisted.
·Leave approximately 80 mm (3.15 in.) loose in the twisted wires around the connector.
·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.)
| *a | Bypass Wire |
Do not use bypass wiring between connectors.
- NOTICE:
- ·
The ability of the twisted bus lines to resist interference will be lost if bypass wiring is used.
·Do not use a twisted pair of wires for bypass wiring.
CONNECTOR HANDLING
| *a | Tester Probe |
When checking resistance with a tester, insert the tester probes from the backside (harness side) of the connector.
| *a | Service Wire |
Use service wires to check the connector if it is impossible to check continuity from the rear of the connector.
