Test roof Ultrasonic Sensor (USS) performance by checking the sensor correctly detects an obstacle located at a distance of 30 cm.
TEST-SELF_BCFALCD_DRV_USS-ROOF-WITH-OBSTACLE
Test roof Ultrasonic Sensor (USS) performance by checking the sensor correctly detects an obstacle located at a distance of 30 cm.
TEST-SELF_BCFALCD_DRV_USS-ROOF-WITH-OBSTACLE
Test passenger side Ultrasonic Sensor (USS) performance by checking the sensor correctly detects a 2.5 cm wide pole at a 60 cm distance. This should only be performed using the Falcon Door USS target (Part Number 1095806-00-A). It ensures the pole dimensions and location meet the test criterias.

TEST-SELF_BCFALCP_PAS_USS-DOOR-WITH-OBSTACLE
Test roof Ultrasonic Sensor (USS) performance by checking the sensor correctly detects an obstacle located at a distance of 30 cm.
TEST-SELF_BCFALCP_PAS_USS-ROOF-WITH-OBSTACLE
Runs a high-level routine that outputs system information related to navigation. Result of Pass means only that the routine ran and does not indicate whether an issue is present.
TEST-BASH_ICE_X_CHECK-NAVIGATION
The procedure tests the amplitude of the Near Field Communication (NFC) reader in the B-pillar controlled by the Security Controller (VCSEC).
PROC_VCSEC_DRV_BPILLAR-NFC-AMPLITUDE
Returns vehicle to default motor mode (All-Wheel Drive (AWD) for Cybertruck). Both motors are enabled.
