DTC SUMMARY

MALFUNCTION DESCRIPTION


These DTCs are stored when the rear motor temperature sensor output is abnormal. The cause of this malfunction may be one of the following:

Hybrid vehicle control ECU assembly malfunction
·

Hybrid vehicle control ECU assembly internal malfunction


Rear motor temperature sensor malfunction
·

Internal rear motor temperature sensor malfunction

·

Open or short in rear motor temperature sensor


Wire harness between the rear motor temperature sensor and hybrid vehicle control ECU assembly
·

The connectors are not connected properly

·

Foreign matter or water on the connector terminals

·

Open or short in wire harness


HINT:

If any of these DTCs are stored, the rear motor temperature sensor is malfunctioning and the self-protection function may not operate. Therefore under certain high load driving condition, the temperature of the rear motor (MGR) becomes high. If the self-protection function does not operate, the rear motor (MGR) may malfunction and cause the vehicle to enter fail-safe mode.



DESCRIPTION

The resistance of the thermistor built into the rear motor temperature sensor changes in accordance with changes in the rear motor temperature. The lower the rear motor temperature, the higher the thermistor resistance. Conversely, the higher the rear motor temperature, the lower the resistance.

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 hereEngine / Hybrid System>HYBRID / BATTERY CONTROL>HYBRID CONTROL SYSTEM>UTILITY


1.

Connect the GTS to the DLC3.

2.

Turn the power switch on (IG) and turn the GTS on.

3.

Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).

4.

Turn the power switch off and wait for 2 minutes or more.

5.

Turn the power switch on (IG) and turn the GTS on.

6.

With the power switch on (IG) and wait for 5 seconds or more.

7.

Enter the following menus: Powertrain / Hybrid Control / Utility / All Readiness.

8.

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.
