Clear filtersTests the connectivity of the rear left seatbelt buckle sensor to the left vehicle controller (VCLEFT) ECU.
TEST-SELF_VCLEFT_REAR-L_SEATBELT-BUCKLE
Tests the connectivity of the rear left seatbelt buckle sensor to the left vehicle controller (VCLEFT) ECU.
TEST-SELF_VCLEFT_REAR-L_SEATBELT-BUCKLE-HYDROXIDE
Tests if the second row HVAC panel duct thermistor is operating as expected and whether it is reporting fault conditions.
TEST-SELF_VCLEFT_X_HVAC-SECOND-ROW-THERMISTORS
Folds the seat on one side and executes the functional test on the other side
TEST-SELF_VCLEFT-VCRIGHT_RECLINE-FOLD-AND-FUNCTIONAL
Tests the connectivity of the second row seats to the right vehicle controller (VCRIGHT) ECU.
TEST-SELF_VCRIGHT_2R_7-SEATER
Tests the connectivity of the second row seats to the right vehicle controller (VCRIGHT) ECU.
TEST-SELF_VCRIGHT_REAR_SEAT
Tests the connectivity of the second row seats to the left vehicle controller (VCLEFT) ECU.
TEST-SELF_VCLEFT_2R_7-SEATER
The test sets the monitor threshold of the charging SOC (State of Charge) controlled by the Front Vehicle Controller (VCFRONT).
TEST-SELF_VCFRONT2_X_CHARGE-SOC-MONITOR
The test sets the monitor threshold of the charging SOC (State of Charge) controlled by the Front Vehicle Controller (VCFRONT).
TEST-SELF_VCFRONT_X_CHARGE-SOC-MONITOR
Tests for power, connection, and communication of the shut-off valve controlled by the Front Vehicle Controller (VCFRONT2).
TEST-SELF_VCFRONT2_X_SOLENOID
Tests for power, connection, and communication of the shut-off valve controlled by the Front Vehicle Controller (VCFRONT).
TEST-SELF_VCFRONT_X_SOLENOID
This routine checks if the wheel alignment has been disturbed after a suspension repair. Drive the vehicle on a straight road above 30kph/18mph. If the alignment has changed, the routine will indicate that a wheel alignment is required.
TEST-SELF_EPAS_X_STEERING-CENTER-OFFSET-SERVICE
Tests up/down and in/out movement of the steering column by shortly moving the steering column in each direction.
TEST-SELF_VCLEFT_X_STEERING-COLUMN
The self-test checks the Steering Wheel Controller (SWC) ECU communication with the Left Vehicle Controller (VCLEFT) ECU on the Local Interconnect Network (LIN) bus network.
TEST-SELF_VCLEFT_X_SWC
Model 3 Non-heat-pump ONLY - Stops coolant valve flow test
TEST-SELF_VCFRONT_X_THERMAL-COOLANT-VALVE-FLOW-STOP
Tests the electrical connection between the Tesla Air Suspension (TAS) ECU and the compressor.
TEST-SELF_TAS_X_COMPRESSOR
Tests the electrical connection between the air suspension compressor, the boost valve, the exhaust valve, and the compressor ground return connection.
TEST-SELF_TAS_X_COMPRESSOR-VALVE
Tests the electrical connection between the air suspension compressor, the boost valve, the exhaust valve, and the compressor ground return connection.
TEST-SELF_TAS_X_COMPRESSOR-VALVE
Tests the electrical connection of the air suspension valve block reservoir valve, corner valves, and pressure sensor.
TEST-SELF_TAS_X_VALVE-BLOCK
Tests the electrical connection of the air suspension valve block reservoir valve, corner valves, and pressure sensor.
TEST-SELF_TAS_X_VALVE-BLOCK
Tests if the Air Quality Sensor (AQS) is connected to and communicating with the Local Interconnect Network (LIN) bus. This routine confirms the AQS is present, responding, and not reporting fault conditions.
TEST-SELF_VCBATT_X_AQS
Tests if the battery coolant pump is electrically connected and operating as expected. The pump will be activated and the Vehicle Battery Controller (VCBATT) will monitor current feedback to verify proper electrical connection.
TEST-SELF_VCBATT_X_COOLANT-PUMP-BATTERY
Tests if the chiller coolant pump is electrically connected. The chiller coolant pump will be activated and its electrical feedback will be monitored to verify proper electrical connection.
TEST-SELF_VCFRONT_X_COOLANT-PUMP-CHILLER
Tests if the front and rear map light ECUs are connected to and communicating with the Local Interconnect Network (LIN) bus.
