MALFUNCTION DESCRIPTION
The hybrid vehicle control ECU assembly and airbag sensor assembly detect that a collision has occurred and shut off the system main relay.
The cause of this DTC may be one of the following:
Collision is detected
Detection sensor system malfunction
Airbag system malfunction
Hybrid vehicle control ECU assembly malfunction
Communication malfunction between airbag sensor assembly and hybrid vehicle control ECU assembly
Hybrid vehicle control ECU assembly communication malfunction
The hybrid vehicle control ECU assembly receives a signal that indicates a collision from the airbag sensor assembly to detect a collision. After detecting a collision, the hybrid vehicle control ECU assembly shuts off the high voltage systems for safety.

After repair has been completed, clear the DTCs and then check that the vehicle has returned to normal by performing the following All Readiness check procedure.
Connect the GTS to the DLC3.
Turn the power switch on (IG) and turn the GTS 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 GTS on.
With power switch on (IG) and wait for 5 seconds or more.
Enter the following menus: Powertrain / Hybrid Control / Utility / All Readiness.
Check the DTC judgment result.
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.
Check the vehicle condition.
