Disables the hard stop feature on the front passenger seat. This allows the seat to travel beyond its set physical travel limits. The hard stop feature must be re- enabled after running this routine.
PROC_VCSEATP_FRONT-SEAT-DISABLE-HARD-STOP
Disable Integrated Dynamic Brake (IDB) leak protection mode
PROC_IDB_DISABLE-LEAK-PROTECTION
Disarms the Restraints Control Module (RCM)
PROC_RCM_DISARM
Lists the amount of free disk space on each partition.
TEST-BASH_ICE_X_DF
Checks disk usage in a list of paths. Use this task when the filesystem is running low on free disk space (see Disk Space Check). The results include a number in Megabytes for each directory.
TEST-BASH_ICE_X_CHECK-DISK-USAGE
Test the functionality of the center display tilt mechanism actuators. Display will tilt left and right during the test.
TEST-SELF_VCLEFT_X_DISPLAY-ACTUATORS
Runs the display cable stress test script on the vehicle to diagnose a center display that has a flickering screen and is unresponsive to touch. The estimated time to complete is 40 seconds.
TEST-BASH_ICE_X_DISPLAY-CABLE-STRESS-TEST
Tests power and connection of the center display. Communication is established via either display port or High-Definition Multimedia Interface (HDMI).
PING-BASH_DISPLAY
Request that the Power Manager turns the display off.
PING-BASH_DISPLAY_POWER_OFF
Requests that the Power Manager turns the display on.
PING-BASH_DISPLAY_POWER_ON
Test the functionality of the center display tilt mechanism
PROC_VCLEFT_DISPLAY-MECH-TEST
The procedure generates a system report that displays memory, Central Processing Unit (CPU), task and swap utilization followed by currently running tasks. This is useful for checking a process for excessive memory or CPU usage.
TEST-BASH_ICE_X_TOP
Calibrates the center display tilt mechanism actuators. Display will tilt during the calibration.
PROC_VCLEFT_DISPLAY-MECH-CALIBRATE
Tests all (center, instrument cluster unit, rear) displays for power and connection
PING-BASH_DISPLAY_ALL
ALWAYS RUN AFTER BLEED! Used to check for air or leakage in the DPB
TEST-SELF_DPB_LEAKAGE-AND-AIR-MONITORING
This will test the DPB connection to the ESP as well as potential leakage air in the system
TEST-SELF_DPB_AIR-AND-LEAKAGE
Routine to bleed the DPB and/or ESP hydraulic circuit
PROC_DPB_ESP_REPAIR-BLEED
Selftest to perform automatic brake fluid change
PROC_DPB_BRAKE-FLUID-CHANGE
Validates all 4 brake lines by measuring DPB plunger stroke values and validating that none are blocked, have air or leakage
TEST-SELF_BRAKE_X_DPB-ESP-SYSTEM-CHECK
Applies pressure to each individual corner in turn to compare the output values and validate the brakes. 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-SELF_BRAKE_X_DPB-ESP-CORNER-STIFFNESS-TEST
Routine to activate or de-activate the assembly mode on DPB
PROC_DPB_X_ASSEMBLY-MODE
Applies pressure to each individual corner in turn to compare the output values and validate the brakes. 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-SELF_BRAKE_X_DPB-ESP-CHECK-REAR-CROSSED-LINES
DPB Tandem Master Cylinder test. Do not press for the predaly before the test starts. A small "click" can be heard once the pedal is ready to be pressed.
TEST-SELF_DPB_TMC-BRAKE-PEDAL-PRESS
Resets the Decoupled Pedal Brake (DPB) Electronic Control Unit (ECU). Reset is executed via Unified Diagnostics Services (UDS) over the Controller Area Network (CAN).
TEST-RESET_DPB
