A/T Diagnosis General DescriptionS6RW0D5101004
This vehicle is equipped with an electronic transaxle control system, which controls the automatic shift up and shift
down timing, TCC operation, etc. suitably to vehicle driving conditions.
TCM has an On-Board Diagnosis System which detects a malfunction in this system.
When diagnosing a trouble in transaxle including this system, be sure to have full understanding of the outline of “On-
Board Diagnostic System Description” and each item in “Precautions in Diagnosing Trouble” and execute diagnosis
according to “A/T System Check” to obtain correct result smoothly.
NOTE
There are two type of On-Board Diagnostic System, Euro OBD system and non-Euro-OBD system
depending on the vehicle specification.For identification, refer to “Precaution on On-Board Diagnostic
(OBD) System in Section 1A”.
