Check that the ANC A2B Bus that connects all the ANC microphones, accelerometers are working
TEST-BASH_SPK_X_A2B-ANC-CHECK
Create a report of vehicle states such as UI Mode, BMS State, Timezone, and more. This is useful for verifying vehicle state before performing a remote repair.
TEST-BASH_ICE_X_CAR-STATUS
This test ensures several important processes are running on the CID.
TEST-BASH_CID_X_CHECK-PROCESS
Check ride height calibration of the Continental air suspension. Please input the ride height measured at each corner of the vehicle.
PROC_EAS_X_CHECK-RIDE-HEIGHT-CALIBRATION
The check databases test checks pragma integrity for all databases and searches for errors.
TEST-BASH_ICE_X_CHECK-DATABASES
Query the current power-off status for a specific component. Returns the status and remaining timeout for any active power-off request.
PROC_VC_X_STATUS-POWER-OFF-REQUEST
Computes a hash for a given file to verify file integrity. Can be used for validating newly created navigation maps, images, or system files.
TEST-BASH_ICE_X_CHECK-HASH
Computes a hash for a given file to verify file integrity. Can be used for validating newly created navigation maps, images, or system files.
TEST-BASH_ICE_X_CHECK-HASH
Analyze mounted devices, logical volumes, and disk usage.
TEST-BASH_ICE_X_CHECK-SYSTEM
Returns the signature of an available odin patch on firmware server if one is released
TEST_ICE_X_ODIN-PATCH-AVAILABLE
Check the electrical connection between the MCU and the Pedestrian Warning Speaker
TEST-BASH_SPK_X_PWS-CHECK
Check the electrical connection between the MCU and all the speakers that are connected directly to the MCU
TEST-BASH_SPK_X_MCU-CHECK
Check the Tuner Availability/Connection for Hirschmann Gen3 Tuners
TEST_GEN3_TUNER
Reads vehicle's total historical AC charge KWh, ensures above threshold
PROC_ICE_X_CHECK-MIN-AC-CHARGE
Reads vehicle's total historical DC charge KWh, ensures above threshold
PROC_ICE_X_CHECK-MIN-DC-CHARGE
Read the /home filesystem superblock to display information like available inodes and memory blocks. This will provide insight into filesystem-related issues such as insufficient inodes or disk space. The most helpful result is the 'Free Inodes' line which should show a number over 10,000.
TEST-BASH_ICE_X_READ-HOME-PARAMS
Checks whether the left turn signal indicator light is on and functioning as expected. This routine monitors CAN to confirm whether the indicator light is turned on.

TEST-BASH_SPK_X_MCU-PREM-CHECK
Check the electrical connection between the MCU speakers and check PWS speaker
TEST-BASH_SPK_X_MCU-PWS-CHECK
Tests the electrical connection between the Media Control Unit (MCU) and speakers.
TEST-BASH_SPK_X_MCU-CHECK
Check the electrical connection of all the speakers (Base-Amp, Premium-Amp and PWS speaker)
TEST-BASH_SPK_X_MCU-PWS-PREM-CHECK
Tests if the four overhead map lights are electrically connected by measuring current draw when powered. This routine will output current draw statistics for each map light, including threshold, minimum and maximum current, average current, and standard deviation.
TEST-SELF_VCLEFT_OVERHEAD_MAPLIGHTS
Check the electrical connection of all the speakers (Premium-Amp)
TEST-BASH_SPK_X_PREM-CHECK
