DTC

P0AED11

Drive Motor Inverter Temperature Sensor "A" Circuit Short to Ground

DTC

P0AED15

Drive Motor Inverter Temperature Sensor "A" Circuit Short to Battery or Open

DESCRIPTION

The motor generator control ECU (MG ECU), which is built into in the inverter with converter assembly, detects the temperature of the motor inverter using the motor inverter temperature sensor. The inverter cooling system operates independently of the engine cooling system. The motor generator control ECU (MG ECU) uses signals from the motor inverter temperature sensor to check the effectiveness of the inverter cooling system. If necessary, the motor generator control ECU (MG ECU) will limit inverter output to help prevent inverter overheating. The motor generator control ECU (MG ECU) also detects malfunctions in the motor inverter temperature sensor and its wiring.

DTC No.

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
When clearing the permanent DTCs, refer to the "CLEAR PERMANENT DTC" procedure.
Click here

Connect the Techstream to the DLC3.
Turn the power switch on (IG) and turn the Techstream on.
Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
Turn the power switch off and wait for 2 minutes or more.
Turn the power switch on (IG) and turn the Techstream on.
With power switch on (IG) and wait for 5 seconds or more. [*1]
HINT:

[*1]: Normal judgment procedure.

The normal judgment procedure is used to complete DTC judgment and also used when clearing permanent DTCs.
Enter the following menus: Powertrain / 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 or N/A, perform the normal judgment procedure again.
