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. |

HINT: If P160600 or P160604 is output, the hybrid system cannot be started unless the DTCs are cleared using the Techstream. Related Data List |
DTC No. | Data List | |
P160600 |
- Airbag Status (Collision)
- Airbag Status (Normal)
| | P160604 | 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 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.
