DESCRIPTION

The motor generator control ECU, which is built into the inverter with converter assembly, monitors its internal operation and will store DTCs if it detects a malfunction.

If any of the following DTCs are output, replace the inverter with converter assembly.

CONFIRMATION DRIVING PATTERN

HINT:

After repair has been completed, clear the DTC and then check that the vehicle has returned to normal by performing the following All Readiness check procedure.

Click here

Connect the Techstream to the DLC3.
Turn the ignition switch to ON and turn the Techstream on.
Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
Turn the ignition switch off and wait for 2 minutes or more.
Turn the ignition switch to ON and turn the Techstream on.
With ignition switch ON and wait for 15 seconds or more.
Enter the following menus: Powertrain / Rear Motor Generator / Utility / All Readiness.
Check the DTC judgment result.
HINT:
- If the judgment result shows NORMAL, the system is normal.
- If the judgment result shows ABNORMAL, the system has a malfunction.
- If the judgment result shows INCOMPLETE, perform driving pattern again.

PROCEDURE
