IMPORTANT
When 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.
Before replacing TCM, perform TCM input/output signal inspection and make sure whether TCM functions properly or not. (See page AT-7044.)
After performing each TROUBLE DIAGNOSIS, perform "DTC (Diagnostic Trouble Code) CONFIRMATION PROCEDURE". The DTC should not be displayed in the "DTC CONFIRMATION PROCEDURE" if the repair is completed.
It is very important to perform functional tests whenever they are indicated.
Extreme care should be taken to avoid damage to O-rings, seals and gaskets when assembling.
When 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 "Changing CVT Fluid" in the MA section when changing CVT fluid.
Service Notice or Precautions
FAIL-SAFE
The 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 "L" or "D". The customer may complain of sluggish or poor acceleration.
When the ignition key is turned "ON" following Fail-Safe operation, SPORT indicator lamp blinks for about 8 seconds. [For "TCM SELF-DIAGNOSTIC PROCEDURE (No Tools)", refer to AT-7029.]
The blinking of the SPORT indicator lamp for about 8 seconds will appear only once and be cleared. The customer may resume normal driving conditions.
Always follow the "WORK FLOW" (Refer to AT-7036).
The SELF-DIAGNOSIS results will be as follows:
