Theory Of Operation

WARNING: This page is about a different car, the 2024 RAM ProMaster EV. However, it is still accessible from the selected car via links, so may be relevant.

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