Suspension calibration in Service Mode after repair

Description

After suspension repair (replacing arms, shocks), calibration with Tesla software is required. An on-screen error without calibration appears only on S/X with air suspension; on 3/Y after replacing arms a wheel alignment per the manual is mandatory, while Service Mode is used for the offset test drive and related routines. Some shops forget or don't know how to do it.

Solution

1. Calibration only with Tesla software: Service Mode / Service Mode Plus, and air suspension ride height calibration with Toolbox 3.
2. Software alone won't cut it: you need to understand the whole process and follow the manual.
3. If the shop didn't calibrate, don't accept the car with an error; demand it be redone.
4. Documentation: service.tesla.com.
