Collision detected or Collision Sensor Connection (Open) System Internal Failure |
DTC SUMMARY
MALFUNCTION DESCRIPTION
The hybrid vehicle control ECU and airbag ECU 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 ECU 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 ECU assembly to detect a collision. After detecting a collision, the hybrid vehicle control ECU shuts off the high voltage systems for safety.

- 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.
