Service procedures

TEST_FRONT_LIGHTS

A all-in-one test for the exterior lights on the Model X. During the test, all front or rear exterior lights will illuminate for 5 seconds and the front or rear body controller will look for any errors. Pass or fail results will be returned for every light. Note: the park lights (hockey sticks) and turn signals will turn on at the same time and the color will be peach (mix of orange and white). This is expected.

TEST_REAR_LIGHTS

A all-in-one test for the exterior lights on the Model X. During the test, all of the front exterior lights will illuminate for 5 seconds and the front body controller will look for any errors. Pass or fail results will be returned for every light. Note: the front park lights (hockey sticks) and turn signals will turn on at the same time and the color will be peach (mix of orange and white). This is expected.

Service procedures

Thermal Fluid Fill and Drain

Starts or stops the coolant and/or refrigerant fluid fill and drain routine. 'Start' will set the coolant valve to Series mode with the radiator 50% bypassed, chiller valve 50% bypassed, and all coolant pumps off. This routine fully opens the chiller evaporator expansion valve and chiller solenoid (if equipped). It also disables the refrigerant compressor. This routine fails if another routine is already running on the Thermal Controller or if the vehicle is charging or in Drive. 'Stop' will cancel the fluid fill and drain routine and restore normal operation. Stopping this routine will fail if it is already stopped.

Thermal Fluid Fill/Drain

Places the coolant valve in series mode and turns the coolant pumps off for draining or filling coolant. In addition, this routine opens the Electronic Expansion Valves (EXVs) for recovering or charging refrigerant.
