Precautionary measures
1. Before performing work on electrical equipment, disconnect the cable from the negative terminal of the battery.
2. If the battery needs to be disconnected for a check or repair, be sure to disconnect the negative cable first (-) terminal that is connected to the body (weight) car.
3. When carrying out welding work, disconnect the battery and connectors of the electronic control unit.
4. Do not open the ECU cover unless absolutely necessary, as the ECU's integrated circuit may be damaged by static electricity.
Replacing fuses
1. Before servicing, turn off the ignition and all electrical appliances.
2. Install fuses only of the regulated current rating.
Note: Do not use a fuse with a higher current rating or any other items ("bugs") instead of a blown fuse. This may cause more serious damage or fire.
3. Remove and install the fuse only in a straight line, without unscrewing or swinging. Otherwise, the contacts may move apart too wide and the fuse will not hold in them.
Note: Use the fuse tool to remove and install the fuse (see picture).
4. If the fuse blows again after replacing the fuse, check the circuits for an open or short circuit

2. The pins of the plug connector are numbered from top right to bottom left.
