Subject:
Sephia/Spectra and Rio TCM Logic Revision (Trans/Driveline - 007)
Description:
This bulletin provides information related to a logic change in the Transmission Control Module (TCM) for 2001 MY Rio and 1998 through 2001 MY
Sephia and Spectra vehicles built after 10/18/00.
On vehicles built before 10/18/00, under certain driving conditions the following DTC's may be stored without a true defect being present: P0705,
P0740, P0731, P0732, P0733, and P0734.
TCM's in vehicles built after 10/18/00 use a revised diagnostic routine software to reduce incidence of related DTC's.
The revised TCM should be used to repair affected vehicles experiencing repeat incidence of above mentioned DTC's.
Note:
The part number for the revised TCM's did not change. However, all TCM's currently in PDC stock have the revised logic. When in doubt as to
which TCM version a vehicle is equipped with, use the illustration to properly identify the version.
PRELIMINARY:
^
Familiarize yourself with the procedures outlined in TSB, Transmission/Driveline 003. Obtain an A/T diagnosis worksheet and fill it out as you
proceed.
^
Check A/T fluid for level and appearance. If fluid is burnt or contaminated, transaxle may have to be replaced per instructions in TSB before
proceeding.
^
Check for any (pending) DTC's, record their description and freeze frame data. If any electrical or circuit related DTC's are stored, repair before
replacing TCM or before attempting to correct DTC's that indicate system malfunctions.
^
On repeat repairs, always check the vehicle's repair history to determine previous repairs and whether they were effective. Use repair history as
required to aid in diagnosis and repair approach.
