Tests for power, connection, and communication of the left headlamp controlled by the Front Vehicle Controller (VCFRONT).
TEST-SELF_VCFRONT_L_HCM
Tests the communication of the left headlamp module with the VCBATT ECU.
TEST-SELF_VCBATT_L_HCM
Functional light-up test for upgraded Model Y premium left headlamp endpoints
TEST-SELF_VCFRONT2_X_HEADLAMP-FUNCTIONAL-TEST-V2
Executes a routine to fold the left mirror
PROC_VCLEFT_MIRROR-FOLD
Executes a routine to unfold the left mirror
PROC_VCLEFT_MIRROR-UNFOLD
This tests the functionality of the Left Rear Door Speaker (Base).
TEST-BASH_CID_REAR-L_SPEAKER-LRDO-BASE
This tests the functionality of the Left Rear Door Speaker (Premium).
TEST-BASH_CID_REAR-L_SPEAKER-LRDO
This tests the functionality of the Left Rear Lift Gate Speaker (Premium).
TEST-BASH_CID_REAR-L_SPEAKER-LRLG
Tests auto-addressing and communication of RGB lights controlled by the Left Vehicle Controller (VCLEFT) Electronic Control Unit (ECU). Communication is established via the Local Interconnect Network (LIN) bus.
TEST-SELF_VCLEFT_X_RGB-LIGHTS
Calibrates the front left seat track and motor.
PROC_VCLEFT_SEAT-CALIBRATE
A consolidation of all the ODIN routines required to be run post replacing a left seat controller. The routine will wait for up to 30s for the second row left seat to be unoccupied.
PROC_VCSEAT2L_2R_POST-REPLACEMENT-PROCEDURE
Tests the left second row HVAC airwave vertical and lateral vent actuators. This routine detects whether each actuator is connected and calibrated. Each actuator's end- stop and zero-stop voltage and forward and reverse encoder values will be output.
TEST-SELF_VCLEFT_X_AIRWAVE-SECOND-ROW-LEFT
Moves the left second row seat armrest to the downward endstop then a full range move to test the seat armrest, finally store the seat armrest as its nominal use position.
PROC_VCSEAT2L_X_2R-SEAT-ARMREST-FUNCTIONAL-TEST
Moves the left second row seat to the nominal use position, to the rearward endstop, and repeats another time to record speed history.
PROC_VCSEAT2L_R2-SEAT-ARMREST-HISTORY-GENERATION
Moves the left second row seat to the rearward endstop to perform position calibration, then move seat to the nominal use position.
PROC_VCSEAT2L_2R-SEAT-RECLINE-CALIBRATION
Moves the left second row seat to the rearward endstop to perform position calibration, then move seat to the nominal use position.
PROC_VCSEAT2L_R2-SEAT-CALIBRATION
Tests electrical connection of the left second row seat switchpack, buckle, occupancy, heatpad, fan, absolute position sensor, motor, and encoder.
TEST-SELF_VCSEAT2L_R2-SEAT
Moves the second row seat recliner/backrest to the rearward endstop to perform position calibration, then moves the backrest to the nominal use position.
PROC_VCLEFT_X_2R-SEAT-RECLINE-CALIBRATION
Tests electrical connection of the second row seat adjustable recline sswitchpack, position sensor, motor, and encoder.
TEST-SELF_VCLEFT_X_2R-SEAT-RECLINE-CONTROLS
Attempts to moves the second row seat recliner/backrest rearward, fold the seat, then unfold the seat to the nominal position.
PROC_VCLEFT_X_2R-SEAT-RECLINE-FUNCTIONAL-TEST
Attempts to moves the second row seat recliner/backrest rearward, fold the seat, then unfold the seat to the nominal position.
PROC_VCSEAT2L_X_2R-SEAT-RECLINE-FUNCTIONAL-TEST
Moves the left second row seat track to the rearward endstop then a full range move to test the seat track, then move seat track to the nominal use position.
PROC_VCSEAT2L_X_2R-SEAT-TRACK-FUNCTIONAL-TEST
Executes a test to briefly turn on the left side mirror dimming and verify the voltage rail drops the minimum amount to confirm connectivity.
TEST-SELF_VCLEFT_X_MIRROR-DIM
Tests the connection to the left side repeater camera, and performs a camera firmware update.
PING-HTTP_DAS_L_REPEATER-CAMERA-SCRIPT
