Main Fuse Repair Procedures

Inspection

Be sure to read and observe the "General Safety Information and Caution" before performing any work on the high voltage system. Failure to follow the safety instructions may result in serious electrical injury. Before performing any work, be sure to disconnect high voltage related to the high voltage system (refer to "High Voltage Disconnection Procedure"). Failure to follow safety instructions may result in serious electric shock.

When removing the battery assembly for inspection, the battery system can be connected to the vehicle using SST 0K918-E4100, 0K375-E4100, 0K375-E4200. Before installing the battery assembly, check the battery system operation using the SST.
