P1606-308

HYBRID / BATTERY CONTROL: HYBRID CONTROL SYSTEM: P1606-308, P1606-317: Collision has been detected or Collision Sensor Connection (Open)
P1606-317 - Collision has been detected or Collision Sensor Connection (Open)

DESCRIPTION

The power management control ECU receives a signal that indicates a collision from the airbag sensor assembly to detect a collision. After detecting a collision, the power management control ECU shuts off the high voltage systems for safety.





HINT
If P1606-308 or 317 is output, the vehicle cannot start unless the DTCs are cleared using the Techstream.

INSPECTION PROCEDURE

PROCEDURE

1. CHECK VEHICLE FOR COLLISION DAMAGE

(a) Check the vehicle condition.

Result:
