Clear filtersTests the electrical connectivity of front left fascia lights, including the fog light and side marker light. This routine activates each light and monitors current draw to verify proper electrical connection.
TEST-SELF_VCBATT_FRONT-L_FOG-SIDE-MARKER
Tests the electrical connectivity of front right fascia lights, including the fog light and side marker light. This routine activates each light and monitors current draw to verify proper electrical connections.
TEST-SELF_VCFRONT_FRONT-R_FOG-SIDE-MARKER
Test horn button press
TEST-SELF_HORN_X_BUTTON-PRESS
Tests if the left side repeater light is electrically connected. This routine confirms the Vehicle Battery Controller (VCBATT) can command the repeater and monitors current draw to verify proper electrical connection.
TEST-SELF_VCBATT_L_SIDE-REPEATER
Tests if the radiator coolant pump is electrically connected. The pump will be activated and its electrical current will be monitored to verify proper electrical connection.
TEST-SELF_VCBATT_X_COOLANT-PUMP-RADIATOR
Radio Tuner connection test for all variants
TEST-SELF_RADIOTUNER-ALL
Tests the vehicle thermal system performance, including both powertrain and cabin HVAC heating and cooling with pass or fail result returned. This is the same routine used by Tesla in the manufacturing environment to certify thermal system is performing to specification.
TEST-SELF_VCFRONT2_X_THERMAL-PERFORMANCE
Tests the performance of the vehicle thermal system, the powertrain, and the HVAC heating and cooling. The resulting output is either a pass or fail. Tesla manufacturing uses this routine to certify the thermal system's performance.
TEST-SELF_VCFRONT_X_THERMAL-PERFORMANCE
Tests if the three-way coolant valve is electrically connected and if the valve actuator is mechanically operating as expected. This routine checks position sensor voltage, motor current, and valve's ability to reach commanded positions.
TEST-SELF_VCFRONT_X_THREE-WAY-COOLANT-VALVE
Tests the power, connection, and communication of the Temperature, Humidity, and Sunlight (THS) sensor.
TEST-SELF_VCRIGHT_X_THS
Tests for power, connection, and communication of the left trunk interior illumination controlled by the Left Vehicle Controller (VCLEFT).
TEST-SELF_VCLEFT_X_TRUNK-INTERIOR-LIGHT
Tests for power, connection, and communication of the right trunk interior illumination controlled by the Right Vehicle Controller (VCRIGHT).
TEST-SELF_VCRIGHT_X_TRUNK-INTERIOR-LIGHT
Tests connection and harness of the rear exterior lights controlled by the Right Vehicle Controller (VCRIGHT) Electronic Control Unit (ECU), excluding the fascia light.
TEST-SELF_VCRIGHT_REAR_LIGHTS-V3
Tests connection and harness of the rear fascia lights controlled by the Right Vehicle Controller (VCRIGHT) Electronic Control Unit (ECU).
TEST-SELF_VCRIGHT_REAR_FASCIA-LIGHTS
This self test checks that left liftgate brake light and left liftgate turn light are properly installed by checking that current draw is detected when endpoints are commanded on
TEST-SELF_VCLEFT_REAR-L_LIFTGATE-LIGHTS
This self test checks that the left brake, tail, turn, and reverse light endpoints are properly installed by checking that current draw is detected when endpoints are commanded on
TEST-SELF_VCLEFT_REAR-L_LIGHTS-V2
This self test checks that rear fascia exterior lights (turn signals, tail lights, reverse lights, and rear fog lights) are properly installed by checking that current draw is detected when endpoints are commanded on
TEST-SELF_VCRIGHT_REAR_FASCIA-LIGHTS-V2
This self test checks that right liftgate brake light, right liftgate turn light, left+right liftgate tail lights, license plate lights, and center high mount stop light are properly installed by checking that current draw is detected when endpoints are commanded on
TEST-SELF_VCRIGHT_REAR-R_LIGHTS
This self test checks that the right brake, tail, turn, reverse, rear fog, and license plate light endpoints are properly installed by checking that current draw is detected when endpoints are commanded on
TEST-SELF_VCRIGHT_REAR-R_LIGHTS-V2
Tests the connectivity of the Ultrasonic Sensors (USS) in the front fascia.
TEST-SELF_PARK_FRONT_FASCIA-USS
Tests the communication of the Ultrasonic Sensors (USS) over the party CAN bus.
TEST-SELF_PARK_X_CAN-TESLA-USS
Tests the connectivity of the Ultrasonic Sensors (USS) in the rear fascia.
TEST-SELF_PARK_REAR_FASCIA-USS
Tests the Controller Area Network (CAN) communication of VCBATT with VCFRONT.
TEST-SELF_VCBATT_X_CAN
The self-test checks Front Vehicle Controller (VCFRONT) ECU communication with party Controller Area Network (CAN) bus.
TEST-SELF_VCFRONT_X_CAN
