the alignment machine match the alignment specifications in the Service
Manual. If alignment
specifications do not match, they may need to be manually entered; refer to the
alignment machine's instructions for additional information.
Preparation
-
Ensure that the following are within Tesla-approved specifications before continuing to the next step of this procedure:
- Wheel offset
- Tire size (refer to the tire and loading information label)
- Tire wear
- Tire pressure
CAUTIONDo not perform this procedure on a vehicle that has non-OEM wheels, incorrect wheel offset, tire(s) with less than 4/32 in (3 mm) tread, or incorrect tire pressure. -
Use a diagnostic cable with
an extension cable to connect a laptop with Toolbox 3 to the vehicle. See
Toolbox 3 (Connect and Disconnect).
NoteThe extension cable is necessary so that the laptop can be accessed from outside of the vehicle during this procedure.
-
Perform the lock-to-lock
angle test if the fasteners that secure the steering rack, steering column,
intermediate shaft, tie rods, or front subframe have been loosened or
removed. See Lock To Lock-Angle Test.
NoteDo not disconnect the laptop; it will be used in later steps.
- Turn off the vehicle climate control system.
- Ensure that all pins are inserted into the slip plates and turn plates of the alignment rack.
- Drive onto the alignment rack, and stop the vehicle 1-2 ft (300-600 mm) before the turn plates so that the rolling compensation can be performed in a later step.
-
