AT-7007prose procedureService Notice or Precautions (Cont'd)
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.
EURO-OBD SELF-DIAGNOSIS
CVT self-diagnosis is performed by the TCM in combination with the ECM. The results can be read through the blinking pattern of the SPORT indicator. Refer to the table on AT-7023 for the indicator used to display each self-diagnostic result.
IMPORTANT
The self-diagnostic results indicated by the MI are automatically stored in both the ECM and TCM memories. Always perform the procedure "HOW TO ERASE DTC" on AT-7020 to complete the repair and avoid unnecessary blinking of the MI.
For details of EURO-OBD, refer to EC section ("ON BOARD DIAGNOSTIC SYSTEM DESCRIPTION").
IMPORTANT
Certain systems and components, especially those related to EURO-OBD, may use a new style slide-locking type harness connector. For description and how to disconnect, refer to EL section, "Description", "HARNESS CONNECTOR".
