Alignment Requirement - Suspension

Use the following tables to determine the suspension alignment requirement according to the service performed on the component.

  • 2025-04-07: Added instructions in cases where EPAS alignment check is infeasible.
EC
Indicates that an EPAS alignment check (correction code 31001500) is to be performed. Add the EPAS alignment check as a separate correction in the same activity. If the vehicle passes the EPAS check, an alignment is not necessary. If the vehicle fails the EPAS check, perform an alignment check (correction code 31002100).
Informational PurposesAn informational icon, calling your attention
Note
If unable to perform EPAS alignment check due to service center location/layout or other reasons, perform the four wheel alignment check (correction code 31002100, described below).
AC
Indicates that a four wheel alignment check is to be performed in order to determine whether an alignment adjustment is necessary. Add the alignment check (correction code 31002100) or adjustment (correction code 31002300) as a separate correction in the same activity.

Note
When performing a suspension adjustment on Model Y, always add correction code 31002300 first, which accounts for toe adjustment. If camber/caster adjustments are performed, also add correction code 31000200.
  • Toe adjustment: 31002300
  • Toe and camber/caster adjustment: 31002300 + 31000200
NA
Indicates that No Alignment is necessary, or not applicable.
