HYBRID CONTROL SYSTEM, Diagnostic DTC:P160600, P160604

DTC Code DTC Name
P160600 Collision detected or Collision Sensor Connection (Open)
P160604 Collision detected or Collision Sensor Connection (Open) System Internal Failure

DTC SUMMARY


  1. 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.

  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.

    Tech Tips


    • 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.
