Hybrid Battery Bus / Cable: Service and Repair

High-Voltage Cables









Removal and Installation

WARNING: To prevent the risk of high-voltage shock, always follow precisely all warnings and service instructions, including instructions to depower the system. The high-voltage hybrid system utilizes approximately 300 volts DC, provided through high-voltage cables to its components and modules. The high-voltage cables and wiring are identified by orange harness tape or orange wire covering. All high-voltage components are marked with high-voltage warning labels with a high-voltage symbol. Failure to follow these instructions may result in serious personal injury or death.

1. Depower the High Voltage Traction Battery (HVTB). For additional information, refer to High-Voltage Traction Battery Systems Depowering Service and Repair.
