IWhen connecting or disconnecting pin connectors into or
from TCM, take care not to damage pin terminals (bend or
break).
Make sure that there are not any bends or breaks on TCM
pin terminal, when connecting pin connectors.
IBefore replacing TCM, perform TCM input/output signal
inspection and make sure whether TCM functions prop-
erly or not. (See page AT-41.)
IAfter performing each TROUBLE DIAGNOSIS, perform
ªDTC (Diagnostic Trouble Code) CONFIRMATION PROCE-
DUREº.
The DTC should not be displayed in the ªDTC CONFIRMA-
TION PROCEDUREº if the repair is completed.
IIt is very important to perform functional tests whenever they
are indicated.
IExtreme care should be taken to avoid damage to O-rings,
seals and gaskets when assembling.
IWhen the CVT drain plug is removed, only some of the fluid is
drained. Old CVT fluid will remain in torque converter and CVT
fluid cooling system.
Always follow the procedures under ªChanging CVT Fluidº in
the MA section when changing CVT fluid.
Service Notice or PrecautionsNCAT0004FAIL-SAFENCAT0004S01The TCM has an electronic Fail-Safe (limp home mode). This allows the vehicle to be driven even if a major
electrical input/output device circuit is damaged.
Under Fail-Safe, the vehicle always runs even with a shift lever position of ªLº or ªDº. The customer may com-
plain of sluggish or poor acceleration.
When the ignition key is turned ªONº following Fail-Safe operation, CVT or SPORT indicator lamp blinks for
about 8 seconds. [For ªTCM SELF-DIAGNOSTIC PROCEDURE (No Tools)º, refer to AT-25.]
Fail-Safe may occur without electrical circuit damage if the vehicle is driven under extreme conditions (such
as excessive wheel spin followed by sudden braking). To recover normal shift pattern, turn the ignition key
ªOFFº for 5 seconds, then ªONº.

MEF040DA Perform TCM
input/output signal
inspection before
replacement.

PRECAUTIONS
Precautions (Cont'd)
AT-6

The blinking of the CVT or SPORT indicator lamp for about 8 seconds will appear only once and be cleared.
The customer may resume normal driving conditions.
Always follow the ªWORK FLOWº (Refer to AT-32).
The SELF-DIAGNOSIS results will be as follows:
The first SELF-DIAGNOSIS will indicate damage to the vehicle speed sensor or the revolution sensor.
During the next SELF-DIAGNOSIS, performed after checking the sensor, no damages will be indicated.
OBD SELF-DIAGNOSISNCAT0004S04ICVT self-diagnosis is performed by the TCM in combination with the ECM. The results can be read through
the blinking pattern of the CVT or SPORT indicator. Refer to the table on AT-19 for the indicator used to
display each self-diagnostic result.
IThe self-diagnostic results indicated by the MI are automatically stored in both the ECM and TCM memo-
ries.
Always perform the procedure ªHOW TO ERASE DTCº on AT-16 to complete the repair and avoid
unnecessary blinking of the MI.
For details of OBD, refer to EC section (ªON BOARD DIAGNOSTIC SYSTEM DESCRIPTIONº).
ICertain systems and components, especially those related to OBD, may use a new style slide-
locking type harness connector.
For description and how to disconnect, refer to EL section, ªDescriptionº, ªHARNESS CONNEC-
TORº.

Work Flow=NCAT0024HOW TO PERFORM TROUBLE DIAGNOSES FOR QUICK AND ACCURATE REPAIRNCAT0024S01A good understanding of the malfunction conditions can make troubleshooting faster and more accurate. In
general, each customer feels differently about a problem. It is important to fully understand the symptoms or
conditions for a customer complaint.
Make good use of the two sheets provided, ªINFORMATION FROM CUSTOMERº (AT-30) and ªDIAGNOS-
TIC WORKSHEETº (AT-31), to perform the best troubleshooting possible.
