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