The procedeure reads the full configuration file on the gateway. These settings represent hardware features on the vehicle, such as roof glass and battery variant, in addition to paid features like Autopilot. This Task is similar to Teleforce 'dgc'. It reads directly from the gateway and may be trusted as the best point of reference.
TEST-BASH_ICE_X_READ-SX-GW-CFG
Pressurizes all calipers from IDB.
PROC_IDB_BLEED-CALIPER
Measures brake stiffness for each wheel circuit independently. Stiffness threshold is selected based on chassis, burnished state and brake hardware. If executing with DIAG_LINK_ACTIVE then EPBs will release one at a time, which is required if CHECK_SWAPPED_REAR_LINES is true.
TEST-BRAKE_IDB-CORNER-STIFFNESS
Resets the Integrated Dynamic Brake (IDB) Electronic Control Unit (ECU). Reset is executed via Unified Diagnostics Services (UDS) over the Controller Area Network (CAN).
TEST-RESET_IDB
This routine is used to reset the drive unit immobilizer key. This re-learns the code that pairs the drive unit with the security controller (BCCEN). This routine needs to be performed when either the security controller is replaced or the drive unit is permanently removed from a vehicle.
PROC_BCCEN_X_IMMOBILIZER-RESET
This routine can be used to reset the drive unit immobilizer to the virgin state. This unlearns the code that pairs a drive unit to the security controller. This routine needs to be performed when either the security controller is replaced or the drive unit is permanently removed from a vehicle. Immobilizer reset takes 15 minutes. During this time, DI_immobilizerState will be in RESET, and at the end of the procedure it will become DISARMED. Drive rail must remain on throughout the entire procedure. When the immobilizer reads "Disarmed", the drive unit can be paired with the security controller the next time it is powered on.
PROC_DI_X_IMMOBILIZER-RESET
Check in-car temperature sensor
TEST_RCCM_X_TEMP-SNSR
Requests infotainment system reboot. Gateway (GTW) does not reboot.
PROC_ICE_X_REBOOT
The procedure runs a staged firmware update after 120 seconds.
PROC_ICE_X_INSTALL-UPDATE
Tests instrument cluster unit (ICU) display for power and connection
PING-BASH_DISPLAY_ICU

TEST-BASH_CID_C_SPEAKER-IPC-BASE
This tests the functionality of the Instrument Panel Center Speaker (Premium).
TEST-BASH_CID_C_SPEAKER-IPC
This tests the functionality of the Instrument Panel Left Speaker (Premium).
TEST-BASH_CID_C-L_SPEAKER-IPL
This tests the functionality of the Instrument Panel Right Speaker (Premium).
TEST-BASH_CID_C-R_SPEAKER-IPR
Integrated Dynamic Brake (IDB) Pedal Travel Sensor Calibration
PROC_IDB_CALIBRATE-PEDAL-TRAVEL-SENSOR
Integrated Dynamic Brake (IDB) Pressure Sensor Calibration
PROC_IDB_CALIBRATE-PRESSURE-SENSOR
Tests communication with the Integrated Dynamic Brake (IDB) Electronic Control Unit (ECU). Communication is established via Unified Diagnostics Services (UDS) over the Controller Area Network (CAN).
PING-TP_IDB

TEST_PDM_REAR-PASS_INTER-DOOR-RELEASE
Verifies selfie cam current draw when IR LED is on
TEST-SELF_VCRIGHT_DAS_INTERIOR-CAMERA-LED
Tests interior camera connection and performs camera firmware update.
PING-HTTP_DAS_X_INTERIOR-CAMERA-SCRIPT
Run interior camera fan to detect noise
PROC_VCRIGHT_DAS_RUN-INTERIOR-CAMERA-FAN
