A ground fault monitor continuously monitors for high voltage leakage to the metal chassis while the
vehicle is running. If a malfunction is detected, the high voltage ECU will illuminate the hybrid system
warning light in the instrument cluster.
The high voltage battery relays (SMR1 and SMR2) will automatically open to stop the electrical flow in a
frontal collision that is sufficient enough to activate the supplemental restraint system (SRS).
