DTC SUMMARY

MALFUNCTION DESCRIPTION


The hybrid vehicle control ECU assembly detects that a safety device (interlock) is operated or that there is an open circuit in the detection circuit. (Even if an open circuit occurs while the vehicle is stopped, the system determines that the safety device was operated.)

The cause of this malfunction may be one of the following:

Detection switch system malfunction
·

Inverter with converter assembly malfunction


Low-voltage system malfunction
·

MG ECU malfunction

·

Inverter with converter assembly malfunction

·

CAN communication error between the MG ECU and hybrid vehicle control ECU 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 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 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.
