DTC P1606-308 Collision Detection
DTC P1606-317 Collision Detection

DESCRIPTION

DTC Detection Condition:

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

HINT: If P1608-308 or 317 is output, the vehicle cannot start unless the DTCs are cleared using the intelligent tester.

INSPECTION PROCEDURE

CAUTION:
- Before inspecting the high-voltage system or disconnecting the low voltage connector of the inverter with converter assembly, take safety precautions such as wearing insulated gloves and removing the service plug grip to prevent electrical shocks. After removing the service plug grip, put it in your pocket to prevent other technicians from accidentally reconnecting it while you are working on the high-voltage system.
- After disconnecting the service plug grip, wait for at least 10 minutes before touching any of the high-voltage connectors or terminals. After waiting, check the voltage at the inspection point in the inverter with converter assembly. The voltage should be 0 V before beginning work.

HINT: Waiting for at least 10 minutes is required to discharge the high-voltage capacitor inside the inverter with converter assembly.
