Model 3 / Y Model S / X (legacy) Model S / X (2021+)
Self-tests

Check Rear Center Seatbelt Buckle Sensor Connection

Tests if the rear center seatbelt buckle sensor is electrically connected and can detect the seatbelt latching state by measuring current draw when powered.

TEST-SELF_VCRIGHT_REAR-C_SEATBELT-BUCKLE

Model 3 / Y
Self-tests

Check Rear Right Seatbelt Buckle Sensor Connection

Tests if the rear right seatbelt buckle sensor is electrically connected and can detect the seatbelt latching state by measuring current draw when powered.

TEST-SELF_VCRIGHT_REAR-R_SEATBELT-BUCKLE

Model 3 / Y
Self-tests

Check Rear Right Seatbelt Buckle Sensor Connection

Tests if the rear right seatbelt buckle sensor is electrically connected and can detect the seatbelt latching state by measuring current draw when powered.

TEST-SELF_VCRIGHT_REAR-R_SEATBELT-BUCKLE-HYDROXIDE

Model 3 / Y
Self-tests

Check RHD Driver Seat Occupancy Sensor Connection

Tests if the right-hand drive (RHD) driver seat occupancy sensor is electrically connected and can detect seat occupancy by performing endpoint tests.

TEST-SELF_VCLEFT_DRV_RHD-SEAT-OCCUPANCY-SENSOR

Model 3 / Y
Service procedures

Check Right Turn Signal Functionality

Checks whether the right turn signal indicator light is on and functioning as expected. This routine monitors CAN to confirm whether the indicator light is turned on.

PROC_VCFRONT_R_SIGNAL-LIGHT-RIGHT

Model S / X (legacy)
Service procedures

Check TAS Run Mode.

Check Tesla Air Suspension (TAS) Electronic Control Unit (ECU) mode.

PROC_TAS_X_CHECK-RUN-MODE

Model 3 / Y Model S / X (legacy) Model S / X (2021+)
Diagnostic tests

Check Telephony Microphones

Check the telephony microphone functionality

TEST_TELEPHONY-MICS_X_FUNCTIONAL-CHECK

Model 3 / Y Model S / X (2021+)
Diagnostic tests

Check the speaker audio quality

Test for checking the quality of all the speakers on the vehicle

TEST_SPEAKERS-INFOZ_X_FUNCTIONAL-CHECK

Model 3 / Y
Diagnostic tests

Check Var Data

The test reads the /var filesystem superblock to display information like available inodes and memory blocks. The most helpful result is the 'Free Inodes' line which should show a number over 10,000.

TEST-BASH_ICE_X_READ-VAR-PARAMS

Model 3 / Y Model S / X (legacy) Model S / X (2021+)
Communication checks

CHGPH1 CAN Communication

Tests communication with the Supercharger (CHGPH1) Electronic Control Unit (ECU). Communication is established via Unified Diagnostics Services (UDS) over the Controller Area Network (CAN).

PING-TP_CHGPH1

Model S / X (legacy)
Communication checks

CHGPH2 CAN Communication

Tests communication with the Supercharger (CHGPH2) Electronic Control Unit (ECU). Communication is established via Unified Diagnostics Services (UDS) over the Controller Area Network (CAN).

PING-TP_CHGPH2

Model S / X (legacy)
Communication checks

CHGPH3 CAN Communication

Tests communication with the Supercharger (CHGPH3) Electronic Control Unit (ECU). Communication is established via Unified Diagnostics Services (UDS) over the Controller Area Network (CAN).

PING-TP_CHGPH3

Model S / X (legacy)
Communication checks

CHGVI CAN Communication

Tests communication with the CHGVI Electronic Control Unit (ECU). Communication is established via Unified Diagnostics Services (UDS) over the Controller Area Network (CAN).

PING-TP_CHGVI

Model S / X (legacy)
Service procedures

CID Set Leveling Standard

This routine will raise Model S and X vehicles to the standard ride height setting while they are on the line by commanding the setting on the MCU. Leveling is not a test. It is merely a routine to raise the vehicle to a more ergonomic position for quality checks.

PROC_CID_X_LEVELING-STANDARD

Model S / X (2021+)
Service procedures

CID Set Leveling Very High

This routine will raise Model S and X vehicles to the highest ride height setting while they are on the line by commanding the setting on the MCU. Leveling is not a test. It is merely a routine to raise the vehicle to a more ergonomic position for quality checks.

PROC_CID_X_LEVELING-VHIGH

Model S / X (2021+)
Service procedures

CLADDING_AUTOMATED_FALCD

This is an automated test to ensure the lower cladding modules in the falcon wing door are plugged in and reading valid data from the capacitive sensing circuits. This test must be run while the door is stationary and ran at least 5 seconds after the door has stopped moving. The test will not validate whether the sensors will properly detect objects or not.

PROC_BCFALCD_FALCON-DRV_CLADDING-AUTOMATED-FALCD

Model S / X (legacy)
Service procedures

CLADDING_AUTOMATED_FALCP

This is an automated test to ensure the lower cladding modules in the falcon wing door are plugged in and reading valid data from the capacitive sensing circuits. This test must be run while the door is stationary and ran at least 5 seconds after the door has stopped moving. The test will not validate whether the sensors will properly detect objects or not.

PROC_BCFALCP_FALCON-PASS_CLADDING-AUTOMATED-FALCP

Model S / X (legacy)
Service procedures

Clear Alignment Drift Detected Alert

Clears alignment drift detected alert and disables alert for 2000km.

PROC_DIR_X_CLEAR-ALIGNMENT-DRIFT-DETECTED-ALERT

Model 3 / Y
Service procedures

Clear All E-fuse Power Off Requests

Restore power for ALL components on ALL managing ECUs by clearing all active power-off requests. Normal power management resumes for all feeds.

PROC_VC_X_CLEAR-ALL-POWER-OFF-REQUESTS

Model 3 / Y
Diagnostic tests

Clear and Check BCU DTCs

Clears Diagnostic Trouble Codes (DTCs) in the Brake Control Unit(s) (BCU) and checks whether BCU DTCs set again.

TEST-DTC_BCU

Model 3 / Y
Service procedures

Clear BMS Brick6 Substitution

This routine will clear the BMS brick substitution bit and return the BMS to normal operation. This routine shall ONLY be executed after installing a new/remanufactured HV battery or on rare occasion when instructed to do so by engineering. See Toolbox Article 550300 for more information.
