HYBRID CONTROL SYSTEM, Diagnostic DTC:P1606-308, P1606-317

DTC Code DTC Name
P1606-308 Collision has been detected or Collision Sensor Connection (Open)
P1606-317 Collision has been detected or Collision Sensor Connection (Open)

DTC SUMMARY


  1. MALFUNCTION DESCRIPTION

    The hybrid vehicle control ECU and airbag ECU 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 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.
