PRECAUTION

1. WIRE HARNESS REPAIR




a. When repairing a wire harness, wrap the repaired part with a vinyl tape.

NOTE:
- The CANL wire harness and CANH wire harness must be installed together all the time.
When installing, make sure to twist them.
- The difference in the length of the CANL wire harness and CANH wire harness should be within 100 mm (3.93 in.).




b. Do not perform the bypass wiring between the connectors.

NOTE: If you perform the bypass wiring, the characteristic of the twisted wire harness will be lost.

2. CONNECTOR HANDLING




a. When inserting tester probes into a connector, insert them from the back of the connector.




b. If it is impossible to measure the resistance from the back of the connector, use a repair wire to measure it.
