DTC P1606-308 Collision Detection: Description

The HV control ECU receives collision signals from the airbag sensor assembly CTR, circuit breaker sensor (front collision sensor), circuit breaker sensor RR RH (rear collision sensor right), and circuit breaker sensor RR LH (rear collision sensor left) to detect the destruction of the vehicle. After detecting the destruction of the vehicle, the HV control ECU shuts off the high-voltage systems for safety.
