![]() ![]() Before touching a 273.6V cable or any other cable that you cannot identify, use the tester to confirm that the voltage through the cable is 12V or less. Even after the five minutes have passed, the following precaution should be observed: See Figure 1.Ĭaution: Due to the discharge resistance, it takes at least five minutes before the 273.6V circuit is sufficiently discharged from the condenser in the inverter circuit. Remove the service plug and do not start any repair operation before five minutes have passed. Disconnect the negative (-) terminal cable from auxiliary battery.ġ. Ensure that the charge connector is disconnected. Remove the key from the ignition switch. Be sure to perform repair operations correctly. If no problems are found with these components, proceed with the inverter replacement.Ĭaution: A repair operation incorrectly performed on the hybrid vehicle could cause an electrical shock, leakage or explosion. Check for coolant or air flow obstructions to the inverter heat exchanger and proper radiator side seal condition. ![]() Check for the presence of air bubbles in the cooling system.
