HYBRID CONTROL SYSTEM, Diagnostic DTC:P0A7A-518, P0A7A-811

DTC Code DTC Name
P0A7A-518 Generator Inverter Performance
P0A7A-811 Generator Inverter Performance

DESCRIPTION

For a description of the inverter Click here.

If the generator inverter overheats, has a circuit malfunction or has an internal short, the inverter transmits this information to the MG ECU via the generator inverter fail signal line.

If an abnormal amount of current flows through the generator inverter, the MG ECU detects it and sends a signal to inform the power management control ECU of the malfunction.

DTC No. INF Code DTC Detection Condition Trouble Area
P0A7A 518 Generator inverter fail signal detection (overcurrent due to hybrid vehicle transmission assembly malfunction)

  • Inverter with converter assembly

  • Hybrid vehicle transmission assembly

  • Wire harness or connector
811 Abnormal generator current value detection (hybrid vehicle transmission assembly malfunction)

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 removing 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 Click here.

    Tech Tips

    Waiting for at least 10 minutes is required to discharge the high-voltage capacitor inside the inverter with converter assembly.

Note

After turning the power switch off, waiting time may be required before disconnecting the cable from the negative (-) auxiliary battery terminal. Therefore, make sure to read the disconnecting the cable from the negative (-) auxiliary battery terminal notices before proceeding with work Click here.
