[Key switch]
1. Select a key switch whose B-to-BR circuit (E-ECU power supply circuit) is not open between the ON
and START positions. An instantaneous power interruption of 1 ms or longer may reset the E-ECU and
hinder the engine from starting.
[General]
1. Observe the cable and fuse requirements specified on the standard connection diagram.
2. Use electric cables whose heat resistance is appropriate to surrounding thermal conditions.
3. Ensure no water is trapped inside the coupler when plugging the connector.
4. Clamp the harness to appropriate structures so as to prevent swinging due to vibrations.
5. Do not strain the harness clamp.
6. Use joint couplers or butyl tape to ensure waterproofness at joints.
7. Check that no surge current or voltage occurs in normal working conditions or expectedly abnormal
conditions.
8. Check that no instantaneous power interruption (6.0 V or lower for 1 ms or more) occurs in normal
working conditions or expectedly abnormal conditions.
9. Do not force a measuring or testing probe into the female coupler of the connector.
