Service Notice or Precautions
ATF COOLER SERVICE^ If A/T fluid contains fictional material (clutches, bands, etc.), or if an A/T is repaired, overhauled, or replaced, inspect and clean the A/T fluid cooler mounted in the radiator or replace the radiator. Flush cooler lines with cleaning solvent and compressed air after repair. For A/T fluid cooler cleaning procedure, refer to A/T Fluid Cooler Cleaning. For radiator replacement, refer to REMOVAL.
CHECKING AND CHANGING A/T FLUID
^ Increase ATF oil temperature to 80°C (176°F) first, then check and adjust oil level at 65°C (149°F).
NOTE: The A/T has both water cooling and air cooling systems. The air cooling system has a bypass valve. When ATF oil temperature is at or below 50°C (122°F), it does not flow through the air cooled system. If A/T oil level is adjusted without flow throughout the entire system, the level will be 10mm lower than required. Therefore, all piping should be filled with oil when adjusting level.
OBD-II SELF-DIAGNOSIS
A/T self-diagnosis is performed by the TCM in combination with the ECM. Refer to the table on AT-87, SELF-DIAGNOSTIC RESULT MODE for the indicator used to display each self-diagnostic result. Pinout Values and Diagnostic Parameters
^ The self-diagnostic results indicated by the MIL are automatically stored in both the ECM and TCM memories.
Always perform the procedure on AT-40, HOW TO ERASE DTC to complete the repair and avoid unnecessary blinking of the MIL. General Notes
For details of OBD-II, refer to ON BOARD DIAGNOSTIC (OBD) SYSTEM.
^ Certain systems and components, especially those related to OBD, may use the new style slide-locking type harness connector. For description and how to disconnect, refer to HARNESS CONNECTOR.
