P0A78-523 HBC-289 < COMPONENT DIAGNOSIS > D E F G H I J K L M A B HBC N O P Turning ignition switch off causes the voltage in the inverter to discharge. The inverter voltage is almost 0 V after discharge. The DTC will be stored if the inverter voltage is more than the specified value after discharge. Diagnosis Procedure INFOID:0000000004211947 1. PRECONDITIONING • Before inspecting the high-voltage system or disconnecting the low voltage connector of the inverter with converter assembly, take safety precautions such as wearing insulated gloves and removing the service plug grip to prevent electrical shocks. After removing the service plug grip, put it in your pocket to prevent other technicians from accidentally reconnecting it while you are working on the high-voltage system. • After disconnecting the service plug grip, wait for at least 10 minutes before touching any of the high-voltage connectors or terminals. • Waiting for at least 10 minutes is required to discharge the high-voltage capacitor inside the inverter with converter assembly. >> GO TO 2. 2. CHECK DTC OUTPUT 1. Turn ignition switch ON. 2. Check DTC. Is DTC detected? YES >> Go to Diagnosis Procedure relevant to output DTC. NO >> Replace inverter with converter assembly (See HBC-638, "Removal and Installation" ).
