Overview - Battery Cooling Module: Notes

Observe all of the additional warnings for all work performed on vehicles with the high voltage system. Refer to HIGH VOLTAGE VEHICLES SAFETY PRECAUTIONS and appropriate service information .

WARNING:

Risk of unintended engine start

The ignition must be turned off and the ignition key must remain outside of the vehicle when working on vehicles with a high voltage system.

WARNING:

Handling High Voltage Cables: 

  • Do not stand on or place tools on high voltage cables and their components as it may damage the cable insulation.
  • Never bend or kink high voltage cables forcefully as it may damage the cable insulation.
  • The round high voltage connectors are color coded with an external color ring and are mechanically coded using the guide- or code tabs. Always make certain that the coding matches when connecting the round connector in order to avoid any mechanical damage the high voltage connector.
CAUTION:

There is a risk of electrocution from damaged high voltage components.

Observe The Following When Working Around High Voltage Components And High Voltage Wires:

  • Never work around high voltage components and cables with cutting, deformed, or sharp edged tools, or heat sources such as welding or soldering tools, heated air, and thermal glue.
  • Inspect the high voltage components visually before beginning.
  • Perform a visual inspection of the Electric Drive Power and Control Electronics -JX1-, the Electro-Drive Drive Motor -V141-, the Electrical A/C Compressor -V470- and the high voltage lines when working in the engine compartment.
  • Perform a visual inspection of the high voltage lines and covers when working on the underbody.
  • Perform a visual inspection of the high voltage lines and the Electrobox with the High Voltage System Maintenance Connector -TW- when working in the luggage compartment.
  • Perform a visual inspection on all of the potential equalization cables.

Observe The Following Items When Performing The Visual Inspection:

  • The components do not display any signs of external damage.
  • The high voltage cable insulation and the potential equalization cables are not damaged.
  • The high voltage cables do not display any abnormal deformations.
  • Every high voltage component is marked with a red warning label.
NOTE:

The Battery Regulation Control Module -J840- activates the attachments using the Vehicle Diagnostic Tester in the "Guided Fault Finding" function

For this model line, only vehicles with a high-voltage system were manufactured that had the refrigerant circuit charged with refrigerant R134a.

If it is necessary for the following procedure to perform work near high voltage components, "perform a visual inspection of the high voltage components and cables for damages" and "always follow the warnings when working on the high voltage system". Refer to PERFORMING A VISUAL INSPECTION OF DAMAGE TO HIGH VOLTAGE COMPONENTS AND CABLES ) and appropriate service information .
