What does code U3532 mean?

Q: What does code U3532 mean?

High Voltage System Interlock Circuit K Performance. U3532 indicates that the high-voltage interlock loop for circuit K has reported a performance fault, typically a voltage reading outside the expected range, to the vehicle's control module. The interlock is a safety circuit that confirms all high-voltage connectors and covers are properly seated before the system allows high-voltage power to flow. When the module detects an abnormal voltage on circuit K, it sets this code and may disable the high-voltage system to prevent shock hazards.
