DTC SUMMARY
MALFUNCTION DESCRIPTION
The hybrid vehicle control ECU 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 malfunction
-
Communication malfunction between airbag sensor assembly and hybrid vehicle control ECU
-
Hybrid vehicle control ECU communication malfunction
DESCRIPTION
The hybrid vehicle control ECU 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 shuts off the high voltage systems for safety.
DTC No.

CONFIRMATION DRIVING PATTERN
HINT:
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.
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.
-
Enter the following menus: Powertrain / Hybrid Control / 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 driving pattern again.
