Pinpoint Tests TJ: Inverter Over Temperature Fault: Introduction
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 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.
NOTE:
Under normal operating conditions, the motor electronics cooling system should be able to maintain a temperature of approximately 11°C (20° F) over ambient temperature while driving.
This pinpoint test is intended to diagnose the following:
