The test displays all public keys on the whitelist of the Security Controller (VCSEC) and optionally shows permissions.
TEST_VCSEC_X_DISPLAY-KEY-WHITELIST
List folder filesystem information. User input specefies which folder to examine.
PROC_ICE_X_INFO-DIR-STAT
Tests for power, connection, and communication of the shut-off valve controlled by the Front Vehicle Controller (VCFRONT2).
TEST-SELF_VCFRONT2_X_SOLENOID

Checks the State of Charge (SOC) on the vehicle.
PROC_CID_X_DV-CHARGE-PERCENT-CHECK-NA
Resets all HV battery brick State of Charge (SOC) values based on the latest Open Circuit Voltage (OCV) brick measurements. During normal operation, the HVBMS ECU calculates brick SOCs from multiple data sources. This routine should be executed when the SOC is >90% or <15% and the HV battery has rested (not charging, driving, or climate ON) for at least one hour within that SOC range.
PROC_HVBMS_X_RESET-SOC
Soft-fuse or un-soft-fuse infotainment
PROC_ICE_X_SOFT-FUSE
Resets the HV battery State of Health (SOH) state, enabling a new SOH test to be performed if previously inhibited.
