Lexus ES (XZ10) Service Manual / Engine & Hybrid System / Hybrid / Battery Control / Hybrid Control System (for Lithium-ion Battery) / Collision detected or Collision Sensor Connection (Open) (P160600,P160604)

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.

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

  1. Connect the Techstream to the DLC3.
  2. Turn the power switch on (IG) and turn the Techstream 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 Techstream 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.

    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.
