FAIL-SAFE FUNCTION
If a problem which interferes with the continuous safe operation of the transaxle is identified, the TCM
records a diagnostic trouble code in memory, all so lenoids are turned off, and the module is switched
to limp-in mode.
When limp-in mode is started, the transaxle is locked in gear if a drive gear had previously been
selected. Meanwhile, if
or range was selected, operation is as usual.
If the ignition key is turned to OFF and then back to ON again, limp-in mode is
(a record
is retained).

Turn the ignition switch off before connecting or
disconnecting the scan tool.
Install the interface cartridge cartridge) to the scan
tool
Use the cartridge adapter harness to connect the
scan tool
to the data link connector.
Read the diagnostic trouble codes.
Repair the malfunction while referring to the INSPE CTION
CHART FOR DIAGNOSTIC TROUBLE CODES.
Turn the ignition switch to OFF and then back to ON
again.
Erase the PCM diagnostic trouble code
immediately after erasing the TCM diagnostic troubl e
code.
7.Check that the diagnostic trouble code is normal.
Caution
NOTE
If the transaxle DTC has been set, (excluding cases where
only part of the DTC has been set), the TCM will le t
the PCM know that a DTC has been sent to the PCM
and a problem has occurred. As a result of this, th e PCM
records the DTC for a transaxle problem
After the transaxle has been repaired, the DTC
which has been stored in the PCM will remain
there without being erased, even after the DTC whic h
is store in the TCM has been erased. Therefore the DTC
in the PCM needs to be erased also.
