Inspection Procedure

WARNING: This page is about a different variant/trim than selected.

WARNING:

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. After waiting for 10 minutes, check the voltage at the terminals in the inspection point in the inverter with converter assembly. The voltage should be 0 V before beginning work.

HINT:

Waiting for at least 10 minutes is required to discharge the high-voltage capacitor inside the inverter with converter assembly.
If the vehicle is stopped or parked with the shift lever in the N position for a long time, DTC P3000-388 may be set because the HV battery cannot be charged.
When the engine cannot be started, DTC P3000-388 may be set because the HV battery cannot be charged.
Repeated engine start checks may cause the SOC to drop, resulting in DTC P3000-388 being set. In this case, charge the HV battery using the THS charger.
Cranking the engine once causes the SOC to drop approximately 1%.
Charging the HV battery once (10 minutes) using the THS charger restores the SOC approximately 2%.
Charging the HV battery using the THS charger takes approximately 10 minutes when the battery temperature is 25°C or approximately 30 minutes when the battery temperature is 0°C.
The THS charger is a supplemental charging device that enables the engine to start (READY-on state).
