DTC SUMMARY

  1. MALFUNCTION DESCRIPTION

    The motor generator control ECU (MG ECU), which is built into the inverter with converter assembly, and the airbag ECU assembly detect that a collision has occurred and the motor generator control ECU (MG ECU) built into the inverter with converter assembly outputs a DTC. A collision information signal is also sent to the hybrid vehicle control ECU assembly, which then shuts off the main relay.

    The cause of this DTC may be one of the following:


    • Collision is detected

    • Detection sensor system malfunction


      • Airbag system malfunction

      • Inverter with converter assembly malfunction

      • Communication malfunction between airbag ECU and inverter with converter assembly

DESCRIPTION

When a collision occurs, the motor generator control ECU (MG ECU) built into the inverter with converter assembly receives a collision signal from the airbag ECU assembly and outputs a DTC. A collision signal is also sent to the hybrid vehicle control ECU assembly. After detecting a collision, the hybrid vehicle control ECU assembly shuts off the high voltage system for safety.

DTC No. Detection Item DTC Detection Condition Trouble Area MIL Warning Indicate
P160600 Collision detected or Collision Sensor Connection (Open)

Collision detection

A block signal is received from the airbag ECU assembly.

(1 trip detection logic)

  • Airbag ECU assembly

  • Inverter with converter assembly

  • Airbag system

 Does not come on

Master Warning Light:

P160604 Collision detected or Collision Sensor Connection (Open) System Internal Failure

Collision detection

Multiple wiring malfunctions occur simultaneously.

(1 trip detection logic)

  • Inverter with converter assembly

  • Airbag system

CONFIRMATION DRIVING PATTERN

Tip:

After repairs have 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 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.

    Tip:

    • 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, perform driving pattern again.
