Theory Of Operation

WARNING: This page is about a different variant/trim than selected.

When the Air bag deployed signal is received by the Hybrid Control Processor (HCP), the HCP immediately shuts down the High Voltage (HV) system and sets this DTC. The HCP will command the HV contactors open until the scan tool is used to clear the latched condition.
