DESCRIPTION

The inverter with converter assembly (MG ECU) monitors the inverter current sensor. The MG ECU detects malfunctions in the sensor system and does not detect malfunctions in the high-voltage system.






MONITOR DESCRIPTION

The hybrid vehicle control ECU monitors the generator inverter current sensor. If the hybrid vehicle control ECU detects a fault, it will illuminate the MIL and set a DTC.

INSPECTION PROCEDURE
CAUTION:
- 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.

PROCEDURE

1. CHECK CONNECTOR CONNECTION CONDITION (INVERTER WITH CONVERTER ASSEMBLY CONNECTOR) P0343
NG -- CONNECT SECURELY
OK -- Continue to next step.
2. REPLACE INVERTER WITH CONVERTER ASSEMBLY
HINT: If any DTCs indicating malfunctions in the current sensor circuit are output, overcurrent to the electric vehicle fuse is suspected. In this case, replace the electric vehicle fuse installed on the service plug grip.

NEXT -- REPLACE SERVICE PLUG GRIP
3. CONNECT SECURELY
HINT: If any DTCs indicating malfunctions in the current sensor circuit are output, overcurrent to the electric vehicle fuse is suspected. In this case, replace the electric vehicle fuse installed on the service plug grip.

NEXT -- REPLACE SERVICE PLUG GRIP
